HMF Honda TRX250X 250EX Performance Series Exhaust and Jet Kit Test Review
Вставка
- Опубліковано 24 чер 2018
- Looking to make the most of the little pushrod engine, we installed a Performance Series Exhaust from HMF. Constructed in the USA, HMF offers the Performance Series in a full system only for the 250X. It’s constructed of corrosion resistant stainless steel with a 4” 6063-T6 aluminum silencer shell. The silencer features a 2 1/8” core with a special hole pattern claimed to help increase power evenly throughout the RPM range. The exhaust comes with a USFS approved spark arrestor along with HMF’s quiet core insert. The Performance Series exhaust is said to increase sound output by 4-6db with the Quiet Core knocking sound output back down by 2-4db.
There’s a detectable increase in throttle response. When you crack the gas, the engine feels a little more responsive and willing to build RPMs. We noticed an occasional pop at low RPMs when rolling off the gas, a sign that the pilot jet, which controls fuel delivery at lower RPMs, could stand to be a little larger. The rest of the RPM range ran flawlessly with the airbox lid off. If you ride in colder weather, going up a size or two on your pilot jet is highly recommended. For warmer weather, HMF’s jet kit is sufficient.
Low-end power feels as strong as stock with plenty of grunt to get you rolling or to crawl up some pretty steep inclines. Midrange power seemed stronger than stock powering out of corners, but the best gains came in opening up the top -end. Racing down long straight sections of trail, we found ourselves often bouncing off the rev limiter, upshifting a while after the stock X would have fallen off. There’s added performance available across a much wider RPM range.
The deep throaty sound also adds to the fun sport ATV experience without being annoyingly loud on longer rides. While it won’t turn your 250 into a 400, the HMF Performance Series Exhaust definitely helps up the fun factor on the 250X and EX.
Conclusion
After 8 or 9 rides, the entire exhaust, including the head pipe, looks virtually good as new. With a brushed finish, full system currently retailing for $349.95, HMF’s Performance Series exhaust is nearly identically priced to FMF’s PowerCore 4 Slip-on and is $100 - $200 less expensive than other full system options on the market. Blacked out with its red silencer shell for $449.95, our exhaust featured a custom look to match our machine and still cost less than some off-the-shelf exhausts.
When you can actually feel the performance gains from an aftermarket exhaust, you feel like you got your money’s worth. When an exhaust leaves enough money in your pocket to go riding, that’s even better. Obviously, we are very happy with the HMF Performance Series exhaust for the Honda TRX250X and 250EX

Great video, I hope 2WD sport machines will make a comeback. I miss the good old days, plenty of choice...
crs2crs2 yes, we feel the exact same way.
Man do I agree, how awesome would it be if Suzuki made better quads. The ltz400's aren't bad but the 250 was trash comprared to the Honda, unlike their old lt250s' those things were the bomb.
Robert Tadic I have a Kfx 400 it’s the same as the ltz it’s a plenty
Chase Lukin we love that quad. Suzuki should bring it back as a 450 with a little better swingarm at a little better price.
ATVonDemand yea that would be nice and I’d like them to make a factory racing set up with some kind of exhaust system and Elka shocks or something
The quality of the scripting is top notch, as always. Plenty of informations and very specific. Keep up the good job guys!
ProbeGT2 big thanks. We typically want as much information as possible before we spend our hard-earned money.
You guys make the best atv videos on youtube..no bias and good information. Another way to make some extra power for your atv for a lot less money,,and never have to repack ever again and run quieter than any HMF, FMF etc. Is, find a sport bike stock slip on that will fit your stock exhaust diameter. They flow much better than stock non supersport bikes and atvs,,and most importantly,,,,they sound good, but much quieter and less people complaining...Repacking is a pain after awhile and having a slip on that adds power with some minor jetting tweaks is a great alternative..You guys should look into what stock super sport slip ons would fit on different model ATV's.! i started doing this when I found out that a Suzuki GSXR 600 stock slip on would fit my Suzuki DR650se. I found one on ebay and took off my Powercore 4 or whatever it was called..lol! Best exhaust mod I have ever done,,nice sound, no packing, and extra power over stock.....Also another tip for you to pass on to your loyal readers...Instead of buying an expensive oversize header pipe for your ATV...Simply buy a bit from Lowe's that allows you to smooth out the header pipe welds where it connects to the engine....Do not overdue it as it could crack down the road..No need to go bigger than a stock exhaust port anyhow...Just marketing BS to make a buck.....thanks for the video on some fun little quads.
Gotta love those little 250s
Pe Peroni you can have a lot of fun on a little machine.
Well, there arent many smaller engines in the market for adult atvs, so yeah, little..
You guy made me go out and buy one I primarily ride the Oregon dunes every weekend year round the quads is amazing but so lean and the shaft drive robs power what I have done is gut the spark arrestor and the baffle and still have the cap next is a rejet other that the little honda goes hard it’s not gonna do what a 400 or 450 does but it works for me the spark arrestor baffle delete with a hack saw woke the bike up and no don’t comment oh you need that spark arrestor crap
Only if Honda would've kept their 450r line up..
Herr Tyler yes I wish they would make it again! Some one needs to make a petition haha
@@dumpedclutch8429 I'm sure they made plenty of money off of it because racing teams, and it being a cheaper option to the other 450s it sold well and won plenty of races, and is reliable
I think they release new 450s at random
And the 400x
this thing is better i ride a yfz450r SE but honestly this thing is alot funer cause its smaller
Thank you I’ve been looking to find some more power hidden in that beast.
How about a how to install the exhaust and jetting the 250x! Please!!!
Great video. I love HMF (even have it on one of my own machines right now) and think they are a quality product.
When it comes to the silencers however, everyone should save their money and just buy an exhaust with the appropriate sound decibel that you are comfortable with from the start. I have never found a silencer for an exhaust that isn't ultimately crap.
I straight piped it.
I have two 2018's and put the full HMF exhaust on mine, deleted the smog with a kit from Whitaker Performance out of Ohio and have tried all the jets. The best one is the 110 with the lid off. It will pull the wheels coming out of a turn uphill just throttling, the others felt plugged up and just smooth and like it was starving. I think I will order the jet kit from Duncan Racing to try out the 42 pilot. I know it runs a lot cooler and still goes a long ways on a tank of gas. My wife and I can ride for hours on half tank of gas, granted we are not going very fast through wooded trails and over creeks. I bought these for my kids back Christmas of 17 and they never rode them so we are wearing them out.
I put Ricochet skid plates, Smog delete, Rox risers, color matched Progrips, Motorsport Products Sport Bumper and the full HMF exhaust and they will go anywhere I want, no 4x4 needed. Plus they are light and easy to manage if you get in trouble, unlike an 800lb 4x4.
thats it I'm getting that honda upgrading the exhausts with empire shot gun perfromance kit and nerf tusk bars for that will be my special edition for this year
Have fun with it
Love it !
Earth Smell thanks
ATVonDemand Can you do a small bore utility shootout with Honda Fourtrax 250 , Yamaha Grizzly 350 (2wd) , Suzuki Ozark 250 and Kawasaki Brute Force 300 ? That would be awesome , and I think would get many views since no one ever did one .
Great informational video! I was curious if you guys had to adjust the needle position or the air/fuel mixture screw?
Honestly its hard to recall beyond what we noted in the video. If we were doing another pipe install on one of these we would call Duncan Racing and ask them if they would sell us one of their TRX250X jet kits for an aftermarket exhaust and no airbox lid.
Nice vid
Thanks, glad you liked it.
@@ATVonDemand no way you replied I love your videos !
Might consider getting one for mine now 🤔
Did you get one
@@hunnerhall841 no :(
How many decibels of sound will the bike have after the exhaust installation? (With and without the quiet core insert)?
I got that exhaust system but lately i noticed when I open it up. Sometimes 1st threw 3 gear when I try to stretch the gears out., it act like it bogging. Is that from the jets that was put on it.
Bought one today..
We hope you have a lot of fun with it.
I got the hmf exhaust for mine and it was well worth it. As far as the jet kit goes I didnt feel much of a power increase between the 100, 105 or 110 jet. However using my speedometer app i did test them all, results as follows 100 topped out at 56, 105 topped out at 58 and the 110 topped out at 55. Needless to say I'm sticking with the 105 jet. Don't get me wrong they all felt great!!! Further more I also noticed that with the hmf exhaust kit plus jet kit and air filter upgrades my 250 didn't run as hot as stock, so really less wear on the motor. Its a little expensive but if you want to keep your 250 for any extended period of time its well worth the money.. any adjustment suggestions let me know.
Glad to hear you like the exhaust. Thanks for sharing your jetting experience.
No problem ATVonDemand
Do you run the 105 with lid on?
Yo question
Any reason to go for the competition series exhaust over the performance series shown here?
What’s the difference between the performance one and the competition exhaust? Thanks
Is the exhaust on the 2007-23 TRX250EX the same size as the 87-92TRX250X?
Which Is the weight of the genuin muffler of the Honda TRX 250 ex ? Similar of this video
What jet size do you recommend for winter riding?
There's a lot of us out here that would love to see you do a similar test with the Honda Recon and perhaps some aftermarket wheels and tires maybe a 1-inch spacer that would be great and worthwhile TV
Derrick Kimsey perhaps we will review a 2019 Recon and do a few mods.
In my opinion. When it comes to smaller engines. Dg is the way to go.
A.J.'s ATV Repair shop DG does make some good options for smaller options. I think HMF is generally a better option when going for performance.. and this is coming from a guy who has both in the garage right now.
I have a nice exhaust idk the name on my sisters 90cc but I want to get a Honda trx250
I definitely getting popping when decelerating i put the 110 and the pilot that cane with the kit any fixes found yet ? And also i dont have a silent core in stalled
Mine doing the same thing
try readjusting the idle A/F mixture screw. mine had some popping to it on decel. readjusted that and no has a random pop here and there.
@@Keith_Trostad Is the A/F screw capped off on these carbs? I just picked up a lightly used 2019 and I'm not seeing the adjustment screw
It might be on the new ones. Mine is a 04. Takes a skinny flat blade to reach it. Turn it in all the way. Then turn it out a turn and a half. Start it and get it to running temp. Then adjust the mixture screw in or out till it reaches its fastest idle. After than readjust the idle and then your done
Now can I just add this onto my trx250x, without having to tune it or anything like that? Also, is it really loud? Because I would rather have it not be too loud.
SteakandEggs it’s really loud I have one on mine
@@alexdiaz8608 im buying 1 for my 250 soon love it loud
Y'all should do a gncc build on it
MORRIS GAMING that's a great idea. We have a few other major projects in the works but that would definitely be one for the future.
Its the future 😂 would love to see that build
hi, yesterday i bought a kawasaki mojave 250. They are good for cross country because as it is heavy it is not good for motocross I ask them where I should start (mods) (this good engine) I would like to buy a raptor 250 but it was not enough.
Congratulations on your new machine. The Mojave had the most sophisticated hi tech engine ever used in a 250 four stroke four-wheeler. Are you looking for some suggestions on modifications? Are you planning on trying to set it up for cross country racing?
@@ATVonDemand Thanks, Well if I'm thinking of setting it up for XC racing, give me some suggestions.
Would this be a good atv for someone that about 5 foot 5
Yeah im 6'4 and ride with no problem
Yea it’s fine, if they are still growing then they could tell a difference by how much they can throw the machine around, but it is plenty of height to get off the seat.
what do yall do after viding them and are donme with em?
This machine was on loan from Honda and was purchased by a close friend after the belt was complete.
@@ATVonDemand wow that’s nice
I have a 1987 Honda 250x bone stock
Soon this bike will be gone as well. Poor Honda......
Why you say that?
What did it increase in mph
If an ATV is capable of pulling itself to Red Line where the rev limiter kicks in increasing horsepower will not increase top speed. It will only increase how quickly it gets to it. The only way you get more top speed is if you gear it up. The 250X is shaft drive so that is not possible.
What is the difference between the ex & x
DanielSon Drone there was an older 250X that was around until around 1991 that became the 300EX. If memory serves correctly, the 250EX came out in 2001 later becoming the 250X. Strangely enough, the old-school 250X was actually the more high-tech of the two.
ATVonDemand Thank you for explaining it to me in great detail... I appreciate it...👍
ATVonDemand Wow man you know a hole lot about quads!!!! That's awesome!!!!
Thank God they are still making performance parts even for these mini fart cans
I did the poor mans hmf I gutted out my exhaust and tossed in a 110 and took the air box lid off Jesus it wakes up the bike
Nothing wrong with taking advantage of available horsepower for less.
@@ATVonDemand thank you to you guys and you’re video series on this quad I can shoot out of some pretty deep sand holes on this bike you would be surprised it’s it’s endless smiles.
Does anyone now how to install a jet kit theirs no good videos and I believe you need to do it when installing this
i’m sure you’ve figured it out by now but if you haven’t. all yku do is take the carburetor apart and look into it and you will see the jets in there. just unscrew the jets and screw in the new ones
I know it has a sport clutch so you don't have to use the clutch but jeez use it
Mine wont let me go past 2nd without pulling in clutch
Does your brake lock?
Like the rear brake?
My parking brake has not since i bought it brand new....2019 trx 250x
@@jennylozoya6053 I meant the rear brake
Oh ok sorry ...mine does at lower speeds like to skid and slide...adjust to to your liking
@@jennylozoya6053 my 07 doesnt lock, and I want it to so I can slide through corners and lock the brakes while wheelieing
Does it work with a 2022 model
and I would consider selling it
Fixed my brothers trx250ex mans flips it first ride and he crashed my Crf250r like cmon
LOL, that's a bummer.
Them honda pushrod motors suck and dont last,i rebuilded the top end for friends many times..the bigred 250 and trx300 ohv motors/transmission where far superior, almost bomb proof, able to take decades of severe abuse... Now on to this atv, its a turd a real scam..the yamaha blaster is far superior in all specs categories and was less expensive... If you want a smaller sport atv then yamaha blaster is the best thing available, and easy to find in excellent condition, its extremely reliable and doesn't cost much to run or maintain it
Okay, Boomer.
2 stroke is the definition of high maintenance. What planet are you from?
Hello
Just take the silenset off
Lol that would suck
Does it work on a 2022 model
