This video is Actually exactly what I was looking for in my decision on ⚙ gearing my bike im at 13 in front and was going to try 48 bc of 5th gear but I am now going to try 49 bc its nice have the bottom end right there when you need it..thanks alot
Exactly what I needed running a klx450r and top end was near 100 mph,but fairly tight stuff I was having to feather 2nd to avoid stalling once on the throttle it pulled fine,but in this case I am dropping 1 tooth in the front even though 1st will be very short,2nd won't require as much clutch work. Funny I asked 3 diffent mechanics and got 3 different answers
2020 Yamaha WR450F, street legal enduro. Stock sprockets 13/50. Went to 13/48, still too slow on streets. Tried to install 15/43, but front sprocket is too big diameter and hits plastic chain guards. Will have to just stick with 13/43, or try 14/43. Basically a Super Moto with 32% higher top end, and 32% lower torque. Best advice: just buy a street bike and leave the dirt bike close to stock.
Imho changing one tooth either way on the rear sprocket isnt gonna make a huge difference on most 450s. On the other hand, going up or down one tooth on the front sprocket alone makes most stock bikes either bog or scream. Going up or down 2 teeth on the rear while also going the same direction on the front by one tooth can offer great results. It gets you the equivalent of a half a tooth on the front. Do the math, it works sweet if you have both 13 and 14 tooth fronts with a 51 tooth rear you'll have climbing gears 3.92 and desert gears 3.64 with just a simple front gear swap anytime you like!
What gearing would you recommend for me. I mostly ride desert and explore gravel roads. I occasionally go to the track , but i manly want speed ? I ride a yz450f
+Thomas Crosby lucky you! I had a chance to test drive that bike, it's a beast, almost zero vibration, very light, great bike. Dropping one tooth on rear should do the job. Let us know how it feels once you do it. Good luck!
i have a 2013 CRF450R ( crf 2013-2016 motor are mellow around 51hp). original gearing was 13T/48T it was ok in MX but in woods i stall to much . now i change to 12T/48T am pretty happy with it but i have ordered 50T rear and going to try 13T/50T .
MX bikes are great, but for the slow technical stuff the gears are too tall, you need to play with clutch a lot to keep it from stalling. changing the gearing helps a lot too
Dang, I have 13/49 on my 501. I just feel like the gears are so close, and I def top out at 65mph. I wonder if I went to 14 on the counter, if that would make it more agreeable for long dual sport trips.
HI , thanx for your videos :) they are useful for me specially how to kick start 4t EFI :D it really save my energy and time . i do appreciate if you can answer one of my beginner questions : what dose it mean when you change the front sprocket and people say : the first gear become taller/shorter !? how dose it affect your riding ... i appreciate if you answer my comment or make a video about it.
Amir, shorter the gear gets you have more torque and lower top speed, you need to shift sooner if the gear is short. Lets say you have 10 000 rpm on short gear and you go 45 mph, if you have 10 000 rpm on long gear you would go maybe 55 mph. if you want your bike to be very responsive and pull very hard then you want to make your gears shorter. So if you change front sprocket and you drop a tooth, you are going to gain torque, responsive throttle but your top speed would be lower. it all depends what riding style you have and what kind of riding you do. you can play with it and see how it feels. For example if you ride slow technical stuff and your bike is stalling a lot then you should make your gears shorter, either add tooth on rear sprocket or drop tooth on front. hope that helps, take care!
Dirt N Iron hi again, thank you and it help me understand my bike setting i am a beginner and have a 450 as a first dirtbike i usualy go in woods and deep sands , the previous owner setting is 12Tfront and 50T rear . Now i understand this setting is absolutely right for me .
i have seen the video and understood what you are saying but you have not covered a problem that i am facing with my 4 stroke ktm the 250 sxf. i dont have the specs of my front and rear sprocket but question is on more fundamentals. having more bottom is good for trails but my problem is that everytime after a turn i see a small straight patch i can't open my throttle as my bike just slides out (the surface is slightly hard packed). i feel for this reason i should make my ration taller and go with bigger front tooth(if its 13 then put 14) so i won't have so much sudden bottom end and the power delivery will be gradual, what do you think?
Very informative video. if I gear my sprockets for more top end speed. How much of a top end speed different will it I see in miles per hour. Thanks Merry Christmas.
Hey great videos. I have 2019 rmz 450. And when I'm riding on technical trails I always have to ride the clutch to keep it from stalling. I dont race just trail riding. I run a 13t and 50t can I change that to help me with rpms
Nice video. I have 2017 sxf now and i would like to use it for hard enduro. What gearing would you recommend? How big sprocket should i get at the rear? Thx
Ride it stock first and see how you like it. Remember in the gearing, if you make your gear longer (smaller rear sprocket or bigger front sprocket) you will loose little bit of torque. You need to find that happy medium. Maybe start with one more tooth on front
i do appreciate if you can answer one of my beginner questions : what dose it mean when you change the front sprocket and people say : the first gear become taller/shorter !? how dose it affect your riding ... i appreciate if you answer my comment or make a video about it.
hey i have a rmz 250 and im having troulbe takng off i have to give alot of throttal and clucth i ride trials so the gearing is to long for the trials i stall it out when going slow or taking off my ttr 230 was great on the trials never stalled it out what can i do to make the gearing like the 230 was
Ok I just have a question my brothers honda 450x wheelies way to easy to the point of being dangerous if we let anyone else ride it will changing the rear sprocket make it less likely to wheelie
I'm running a 13/47 stock setup on a kdx 200. It's fast and all but I'd like just a little bit more torque for the trails. Think a 48 tooth rear would do the trick?
i would maybe try 49 rear, it would have less torque but your topspeed would go up. "Primary Drive" is making very affordable steel sprockets, i got one for around $22 i think.. that is good option if you are just playing with gearing.. once you find your numbers, you can get fancy anodized aluminum if you want to..
Nive video man, as always. I have on my 125 front: 12 , rear: 50. The gears are very short but I think that with 125 I should stay like that to have some "torque", if we can use this word on a 125 haha...
What should I put on my 450 for top acceleration top speed is never required I just want to drag race and accelerate to make jumps from a little distance and it’s also for street use
Ok so I’m about to get an 07 rm250 (2 stroke) that I’m going to build for a desert bike. Not looking for too much torque but I’m definitely looking for high speed. I was thinking maybe a 14-47 setup as that’s what I run on my 2000 cr250. Would you recommend that or a 13-48?
@@TheSunnyTrails dude I got that thing dialed it’s amazing road speeds roughly 70mph no issues more than they she wants another gear and it’s not there 😂
Thats what we run on our 300s as well and it did ok on the hills in high desert. But you can always experiment.. 53 will make it feel different for sure
bigger front sprocket and/or smaller rear sprocket. You can add one tooth in front and see the difference, or maybe even 2 teeth if you want to see more of a difference.
I have a wr250f in 2005. I usually ride a lot of hardenduro. Now the gear ratio is 13-48. I think it's a little difficult to make a slow wheelie. Whether to change the 13-50 or 51 one will be better?
I think thats not a bad combination there, the question is how you like it, do you need little more bottom or is it good already? if you need more than add 2 teeth in rear or drop one tooth in front
@@dirtniron i like the bottom. I nead littel more top spead . I have olni 5 gears what do you recomend ? For yamaha yz 125cc 2004 ? I ride off road? And i nead litel mor top spead
I have a yz250f that I use for enduro and I feel like it has to much torque but I’m happy with how fast it is already so what would you suggest? I’m ordering a throttle tamer to ease into the power
you can drop one tooth on rear, it will has little less torque or get one more tooth in front and the difference will be bigger. it will have higher max speed, but you only go as fast as you twist that throttle ;)
I’m converting my pitbike to a supermoto, what’s the best way to increase my gear range as gears 1,2,3 are all too short with gear 4 feels more like gear 3 on a road bike
Ok so I’m about to get an 07 rm250 to build up as a desert bike. Not too concerned with torque but I’m definitely looking for high top speed. I was thinking of running a 14-47 ratio as that’s what I have on my 2000 cr250 and I love it. Would you recommend that or a 13-48?
HI Dirt N Iron. For the first thanx for all your good informative videos. I live in Sweden and i`m new in this outdoor activitie, just bought a Yamaha YZ 250 F (2006 model), my first bike and the first bike i have ridden till now.( thanx to your video about beginners and first bike) I live in a area with deep forest and often rain and snow, much up hill climbing. I don`t want speed,just to be able to ride in the woods. My sprockets are 13-49, and feels so dificult tu climb up hills between trees... Can you please recomand me a good combination? I realy apreciate if you answear me!! sorry my bad english.
+Titbit M.M. congrats to your new purchase. Nice bike! I would suggest to drop one tooth on front so go to 12. But be ready for quite a noticable difference. If you want to take a smaller step then add one tooth on rear, go to 50. Good luck my friend
it depends which direction you go, 1 tooth smaller in front will give you more torque less top speed. adding one tooth to front and rear doesnt make much sense unless you are fine tuning the ratio. adding one tooth front and back is going opposite direction add to the front = more speed less torque (taller gears) add to the rear = less speed more torque (shorter gears)
bigger on the front and smaller on the rear, try to add one tooth on front. You need speed on the street not that much of a low rpm torque. Front sprocket is around $20, so I would definitely try to get bigger front first, I know i say in the video to change rear first, but for supermoto its a different story.
I have a 2011 ktm 150 xc, it has a 13t front and 50t rear. I do alot of enduro riding and track, it doesnt rip as fast through the gears as I would like, but it still has a good top speed. Recommendations?
I'm using a wr450f 52t/13t and the bike wants to rip my arms off. I'll try a 15t or even a 16t to get a little more control for cheap. Any suggestions? I'm pro downhill rider but It's my first dirt bike so I need to gain confidence.
thats too much torque, looks like stock gearing on wr450 is 13/50, I would try 14/50 . If you dont want to spend too much then get primary drive steel sprockets they are durable and cheap. but also maybe 15 - 52 would do the trick. I just think that 52 is too big for WR.
You sound like you know what your doing so my question would be this: I was looking for a KTM125 SX For my son to take to the track but I have been offered a KTM125 EXC for my CRF450r. The EXC is 2015 My 450 is 2014. If you could explain the pros and cons to me although the exc dose not have all the lights etc on it. Would it be a good idea to swap for the EXC Or should I just wait for SX? Fast answer would be great as I have the guy waiting for a swap today:) Cheers in advance any info would be great. TTEA
exc has wide ratio tranny, I am pretty sure its short first gear and tall 4,5,6.. its made for off road so the whole machine is tuned for that. It has different valving in suspension for more plush ride and I think the power is little more tamed too. It is possible to ride that bike on the track as well, but sx would feel better. If you are going to ride track only I would rather wait and get sx. thats what I would do.hope that helps
@@dirtnironThanks for reply really appreciate it:) I was thinking of just waiting for the sx but now I have the dilemma of buying a 2008 for like 2k or around 3k for a 2014-15. Just unsure on how much they changed over the last 6-8 years & if its worth going for the 08:(
@@totheedgeacademyttea9245 if you plan to keep it for long time then I would go for newer one, if it is 1 season transitioning bike then probably 2008... do some research, see what others are saying
hi I bought a 09 kx450f a couple months back and the bike looks like it's been a track bike but my type of riding is tight single trails really rough terrain and I seam to be stalling the bike out alot. when I'm on more open trails the bike rips and there's no issues I was thinking about changing my sprockets but not sure Wich way to go
Jarred Boucher you need to go either bigger on rear or smaller on front sprocket. bike will have more torque it will be snappier from the bottom and your top speed would be lower. if you want bigger change then drop one tooth on front sprocket, it's also cheaper, you can get good front sprocket for around $25. see how you like it. or if you want to take small steps then go one more tooth on rear sprocket. don't forget to cover your clutch all the time, have that finger on it and be ready to pull it in one it gets too technical and bike wants to die. sometimes you just need to feather it a bit. good luck!
thanks for the info. Yeah I need to get better clutch control. before I bought this bike I haven't had a dirt bike in 12 years and now that I have this one I've gone riding out in the trails like 5 times so I have to get better at riding lol. thanks again... great videos!
I ride a xr 100 behind my house with loads of trails and would like to have more power right off the bat I don't need speed I live in a neighborhood what would you recommend??
I need to talk too you about changing my gear ratio would luv your opinion first it's a yz85 that I play around with it I have a few dirt bikes only 2 strokes l have a rm 250 its fast it's got a 14 front and 51 rear leave it just like it is luv the power it has don't ride it like I luv the small yz85 have it's not heavy like my 250 weight pounds the yz only weighs 146 pounds it's fun to ride the stock gear is 14 front 47 rear someone change it to 14 front 48 rear its fast but I want it faster do you think if I change it too a 14 front and 50 rear would I notice the difference please give me your opinion it's not like I race it but I want more torque on take off and good power though the six gears it has what gearing would you recommend plan to do it after Christmas please give me your opinion it matters you no a lot about bikes please let me no what to do I just luv riding small bikes seems so quick and lite let me no what your ratio would be after thanking about it for awhile your opinion would be awesome too me so please let me no I'll be waiting to hear from you michaelholden1
14 - 50 will give you shorter gears, faster to rev, more torque and less max speed. good for the track I think. give it a shot, you can always go back. Maybe you can even try 13 - 48, front sprockets are cheaper
@@dirtniron thank you that's what I will do I'm going to order though amazon thanks for your opinion that means a lot to me you have a merry Christmas you and your family will let you no how things are going in a month or so it's still snow on the ground in North Carolina take care thanks again will be looking forward to more of your videos michaelholden1960@gmail.com
i normally use a 52t sprocket for enduro riding in rocks and hard terrain.. last week i bought a 48t sprocket now i feel my bike wants to raise the front wheel.. is this possible or i have the wrong feeling?!
How about the engine it is possible to consider when changing the sprocket?bcoz i have already tride changing the sprocket but still the speed doesnt change,my engine is a 4strock kawasaki,can you please give some idea what combination of sprocket should i have to combine thanks and God bless.
Wanting to make my 2020 street legal Yamaha WR450F top end go 70 mph with out over speeding rpm on streets. Basically a Super Moto, at least until I can afford to buy an actual street bike.
Can you help me plzzz I have a 2016 kx450f I have 13f and 50r The bike has to much power I want to smooth it out to ride some tracks and trails What would you recomend me ? 13f 49r ? Or 14f 50r idk let me know!
both options will make it less responsive, it will be easier to ride, 14 50 will make bigger difference, try that one firs,t, front sprockets are cheap. There is one more thing you can do to tame it down, there is a product called throttle tamer, it will make your throttle more manageable. I didnt try it myself but heard good things about it. Here is the link: www.g2ergo.com/store/g2-dirt-tamer/ good luck Corey!
@@dirtniron this is exactly what I was looking for!!. Jumped from a honda 150 to a kx 450, and need lower the power until I get more comfortable with it. Like to ride trails

thats odd cuzz most factory race bikes have 13/50 stock.

Taller means you can stay in the gear longer but you have less torque, shorter, your gear is shorter with more torque.

Any recommendations for gearing a 07 rmz250? Street riding mainly, it has 13/49 currently but the gears are short
I have 13 49 on my 450 it pulls good thru to 4th but 5th seems a bit dull I think I get 120/130 max speed but I'm guessing.
Thanks for that. I was wondering about the set up for the 450.

thanks man! I didnt do the conversion myself yet, I will do the video if I do the conversion.. that way its more authentic
What does the stock GasGas 300 two stroke enduro use? 13 51?
I'm running a 13/47 stock setup on a kdx 200. It's fast and all but I'd like just a little bit more torque for the trails. Think a 48 tooth rear would do the trick?
yea, you should be able to feel more torque, although 49 would be more noticeable.
i have a CRF 450 03 and it has a 51 sprocket, but i only go on trail riding, i feel super slow with that sprocket

bigger front sprocket and/or smaller rear sprocket. You can add one tooth in front and see the difference, or maybe even 2 teeth if you want to see more of a difference.
I have a wr250f in 2005. I usually ride a lot of hardenduro. Now the gear ratio is 13-48. I think it's a little difficult to make a slow wheelie. Whether to change the 13-50 or 51 one will be better?
I would probably try 50 first
Dirt N Iron sounds good ！i will try it，thank u
13 49 is good for ofroad or trail? i have crf250L
I have a 2018 crf450r it has 13-49 sprocket. What sprocket size would be best for the trials and going into tight areas
I would try 13-51 probably
@@dirtniron that will make my gears longer
Nice....
I am using 15 - 46... In 125 cc touring trail....
Is this good for climbing terrain offroad and long travels too?
What u suggest
Hi, what bike are you riding with this gearing? I have a KX125 and want to gear it for higher speed.

What would you recomend for yamaha yz 125cc (2004) i have 5 gers! I have 13-49.
I ride offroad?
I think thats not a bad combination there, the question is how you like it, do you need little more bottom or is it good already? if you need more than add 2 teeth in rear or drop one tooth in front
@@dirtniron i like the bottom. I nead littel more top spead .
I have olni 5 gears what do you recomend ? For yamaha yz 125cc 2004 ? I ride off road? And i nead litel mor top spead
I have a yz250f that I use for enduro and I feel like it has to much torque but I’m happy with how fast it is already so what would you suggest? I’m ordering a throttle tamer to ease into the power
you can drop one tooth on rear, it will has little less torque or get one more tooth in front and the difference will be bigger. it will have higher max speed, but you only go as fast as you twist that throttle ;)
Dirt N Iron thanks for the reply
I’m converting my pitbike to a supermoto, what’s the best way to increase my gear range as gears 1,2,3 are all too short with gear 4 feels more like gear 3 on a road bike
smaller rear and bigger front sprocket will get you longer gears
Dirt N Iron thanks bro, appreciate it
Ok so I’m about to get an 07 rm250 to build up as a desert bike. Not too concerned with torque but I’m definitely looking for high top speed. I was thinking of running a 14-47 ratio as that’s what I have on my 2000 cr250 and I love it. Would you recommend that or a 13-48?
I would do 13-48 and get extra front 14 sprocket, those are cheaper than rear and 13 to 14 is quite a noticeable difference
Does 2 teeth down really make such a huge difference? I would have never thought, great informative video, as always. Thanks for posting it.
yea, its quite noticeable, give it a try you will see..
glad you liked it!
Will do, Thanks Rado.
HI Dirt N Iron. For the first thanx for all your good informative videos. I live in Sweden and i`m new in this outdoor activitie, just bought a Yamaha YZ 250 F (2006 model), my first bike and the first bike i have ridden till now.( thanx to your video about beginners and first bike) I live in a area with deep forest and often rain and snow, much up hill climbing. I don`t want speed,just to be able to ride in the woods. My sprockets are 13-49, and feels so dificult tu climb up hills between trees... Can you please recomand me a good combination? I realy apreciate if you answear me!! sorry my bad english.
+Titbit M.M. congrats to your new purchase. Nice bike! I would suggest to drop one tooth on front so go to 12. But be ready for quite a noticable difference. If you want to take a smaller step then add one tooth on rear, go to 50. Good luck my friend
Thank you very much, i have a 52 on rear now, and I love it!
I hawe kxf 450 he is org. I think 13/50 or 51 , what will l geth with one teeth more on front and back ?
it depends which direction you go, 1 tooth smaller in front will give you more torque less top speed.
adding one tooth to front and rear doesnt make much sense unless you are fine tuning the ratio. adding one tooth front and back is going opposite direction
add to the front = more speed less torque (taller gears)
add to the rear = less speed more torque (shorter gears)
@@dirtniron Ok,thanx on advice for a start l will try with one tuth more on rear side,l need torque more as a speed.😉
Sir am riding xr 150 l my problem is that riding in hill no power at all and it’s new bike.can changing chain sprocket give more power?
yes you can get little more pull but you will sacrifice top speed. I am not sure how much would it help

He said "Play with the rear" ....I'm game...
Been following your channel you make good videos hope to see your followers grow! what about sprocket for supermoto?
bigger on the front and smaller on the rear, try to add one tooth on front. You need speed on the street not that much of a low rpm torque. Front sprocket is around $20, so I would definitely try to get bigger front first, I know i say in the video to change rear first, but for supermoto its a different story.
I have a 2011 ktm 150 xc, it has a 13t front and 50t rear. I do alot of enduro riding and track, it doesnt rip as fast through the gears as I would like, but it still has a good top speed. Recommendations?
try 51 rear, it will go faster thru the gears but your top speed will be bit lower
Dirt N Iron Thanks
Very well explained
Glad it was helpful!
I'm using a wr450f 52t/13t and the bike wants to rip my arms off. I'll try a 15t or even a 16t to get a little more control for cheap. Any suggestions? I'm pro downhill rider but It's my first dirt bike so I need to gain confidence.
thats too much torque, looks like stock gearing on wr450 is 13/50, I would try 14/50 . If you dont want to spend too much then get primary drive steel sprockets they are durable and cheap. but also maybe 15 - 52 would do the trick. I just think that 52 is too big for WR.
You sound like you know what your doing so my question would be this: I was looking for a KTM125 SX For my son to take to the track but I have been offered a KTM125 EXC for my CRF450r. The EXC is 2015 My 450 is 2014. If you could explain the pros and cons to me although the exc dose not have all the lights etc on it. Would it be a good idea to swap for the EXC Or should I just wait for SX? Fast answer would be great as I have the guy waiting for a swap today:) Cheers in advance any info would be great. TTEA
exc has wide ratio tranny, I am pretty sure its short first gear and tall 4,5,6.. its made for off road so the whole machine is tuned for that. It has different valving in suspension for more plush ride and I think the power is little more tamed too. It is possible to ride that bike on the track as well, but sx would feel better. If you are going to ride track only I would rather wait and get sx. thats what I would do.hope that helps
@@dirtnironThanks for reply really appreciate it:) I was thinking of just waiting for the sx but now I have the dilemma of buying a 2008 for like 2k or around 3k for a 2014-15. Just unsure on how much they changed over the last 6-8 years & if its worth going for the 08:(
@@totheedgeacademyttea9245 if you plan to keep it for long time then I would go for newer one, if it is 1 season transitioning bike then probably 2008... do some research, see what others are saying
I have a 85cc, i wanna ride in a motorcross track should i go with 13/49? right now i have 13/52 and is too torquie
+JOsue RIvera 3 teeth might be too much, I would try 13 50 first
hi I bought a 09 kx450f a couple months back and the bike looks like it's been a track bike but my type of riding is tight single trails really rough terrain and I seam to be stalling the bike out alot. when I'm on more open trails the bike rips and there's no issues I was thinking about changing my sprockets but not sure Wich way to go
Jarred Boucher you need to go either bigger on rear or smaller on front sprocket. bike will have more torque it will be snappier from the bottom and your top speed would be lower. if you want bigger change then drop one tooth on front sprocket, it's also cheaper, you can get good front sprocket for around $25. see how you like it. or if you want to take small steps then go one more tooth on rear sprocket. don't forget to cover your clutch all the time, have that finger on it and be ready to pull it in one it gets too technical and bike wants to die. sometimes you just need to feather it a bit. good luck!
thanks for the info. Yeah I need to get better clutch control. before I bought this bike I haven't had a dirt bike in 12 years and now that I have this one I've gone riding out in the trails like 5 times so I have to get better at riding lol. thanks again... great videos!
+Jarred Boucher you got yourself a great bike, you won't be lacking power that's for sure. Have fun and thanks for comment!
Hi
I do have ktm 250 sx, I do desert and sand duning ride, what's the best front and rear sprocket ratio?
Thank
+mj75live try 13 48, what are you running now?

It's standard from factory 2011, not sure about it, iam new on it😀
I just checked the manual for the bike, it should be 13 -50
Thanks for the tips man🙏

+bmx media go one tooth smaller on front sprocket, you can pick one up for around $20. See how it works

I need to talk too you about changing my gear ratio would luv your opinion first it's a yz85 that I play around with it I have a few dirt bikes only 2 strokes l have a rm 250 its fast it's got a 14 front and 51 rear leave it just like it is luv the power it has don't ride it like I luv the small yz85 have it's not heavy like my 250 weight pounds the yz only weighs 146 pounds it's fun to ride the stock gear is 14 front 47 rear someone change it to 14 front 48 rear its fast but I want it faster do you think if I change it too a 14 front and 50 rear would I notice the difference please give me your opinion it's not like I race it but I want more torque on take off and good power though the six gears it has what gearing would you recommend plan to do it after Christmas please give me your opinion it matters you no a lot about bikes please let me no what to do I just luv riding small bikes seems so quick and lite let me no what your ratio would be after thanking about it for awhile your opinion would be awesome too me so please let me no I'll be waiting to hear from you michaelholden1
14 - 50 will give you shorter gears, faster to rev, more torque and less max speed. good for the track I think. give it a shot, you can always go back. Maybe you can even try 13 - 48, front sprockets are cheaper
@@dirtniron thank you that's what I will do I'm going to order though amazon thanks for your opinion that means a lot to me you have a merry Christmas you and your family will let you no how things are going in a month or so it's still snow on the ground in North Carolina take care thanks again will be looking forward to more of your videos michaelholden1960@gmail.com

i normally use a 52t sprocket for enduro riding in rocks and hard terrain.. last week i bought a 48t sprocket now i feel my bike wants to raise the front wheel.. is this possible or i have the wrong feeling?!
actually you should feel exact opposite, smaller rear sprocket gives you higher top speed but less torque
maybe you just gained grip instead of loosing energy just by spining your wheels.
@@dirtniron I have my suzuki ts 100 what exact sprocket. Rear and front.i climb hill its very slow running.tnx
"play with your rear" way ahead of you buddy
Informative. Thank you

What would you recommend for trails for an rm 125
i would say drop one tooth on the rear and see how you like it. What do you have now?
How about the engine it is possible to consider when changing the sprocket?bcoz i have already tride changing the sprocket but still the speed doesnt change,my engine is a 4strock kawasaki,can you please give some idea what combination of sprocket should i have to combine thanks and God bless.
what bike, what kind of sprockets and what are you trying to achieve
got a 2016 250 RMZ with 13 49 and i want to have better flow thought tight corners on the mx track should i try to go up to 50?
+Godseverman yes, that's I would do

cool Michael, I am glad it helps!
@@dirtniron what would you recommend for the front and back teeth for enduro riding?

I changed from 15/48 to 14/40 wish me luck 🤣
definitely dont need to go faster, i have a gearing of 3.13 and top speed of 92mph. will also still wheelie in 4th gear
what do you ride?

Can you help me plzzz
I have a 2016 kx450f

The bike has to much power
I want to smooth it out to ride some tracks and trails
What would you recomend me ?
13f 49r ? Or 14f 50r idk let me know!
both options will make it less responsive, it will be easier to ride, 14 50 will make bigger difference, try that one firs,t, front sprockets are cheap. There is one more thing you can do to tame it down, there is a product called throttle tamer, it will make your throttle more manageable. I didnt try it myself but heard good things about it. Here is the link: www.g2ergo.com/store/g2-dirt-tamer/
good luck Corey!
@@dirtniron this is exactly what I was looking for!!. Jumped from a honda 150 to a kx 450, and need lower the power until I get more comfortable with it. Like to ride trails
