I think the 125 / 150 class is the most fun bike out of the 2 stroke class. MX bikes on trails are tons of fun. I think its a good idea, if you can , a 300 for the gnar and a 125 or 150 for the fun factor on trails that let you hit the pipe
Can tell it’s not stock by how you have enough low end to lug it around and the power still picks up and gets into the mid without slipping the clutch. Ride my 125 in the trails as well and go up a lot of steep stuff here in Colorado, had to throw a 51 tooth sprocket on it but if you carry momentum and work the bike right, you can get thru some gnarly stuff. Riding a 125 hard, being in rhythm/flow is so satisfying
Is your 125 a yz? Because YZs are known for down low power. Obviously not as much as the bike in the video, but I don't think you should really need to keep it on the pipe to make it up an incline.
@@foolwithatool2052 My Kx112 can lug all day. I think people don't pay attention to thier PV maintmance and it struggles to close when it should, and it loses all of its low end grunt. I inspect mine every few rides to make sure its working as it should. Kawasaki made is very easy to take the whole assembly out.
@@ncopp4358Yamaha makes it pretty easy as well it’s just most people assume these things are like cars and they’ll just work every single time and that’s why they blow up in 10x sooner than they should
I think its the perfect amount of jet for riding on the trails. Not too rich, but lean enough to keep the plug from fouling. Its just better overall for the bike that way, especially on the trails.
I raced an all stock 5 hour 2018 yz125 during a 50 mile endurance race in the desert, bike ran perfect and womped on the straights very light in the corners you could throw it in a corner and it’ll just dig itself out
I have a cr125 that i ride trails with and im not the best rider so it is a handful as far as finding the right gear and keeping momentum but it has taken me thru some extremely technical terrain with ease
Great bike man sounds amazing. Reminds me of my 2007YZ125. Ive got an ECU on it, vforce, fmf fatty system, and i run 32:1 with race gas. I normally ride mx and keep it screaming but it does just fine in the trails.
Got a 03 yzf250. Bought it but couldn't idle properly. Fixed the carb in 1 day and have a absolute beast of a machine. I do enduro and could be happier. Although 2t is still a amazing bike
I have a 2009 YZ 125, Apex MX head for 91 octane, Keihin Carb, STIC Metering Block, V4r reeds, stock pipe and silencer. Bike is a monster on a mx track, but still works great in the woods. Only have to lean out the air screw a little bit to make it good for trails.
Hi Jake. Would you please list the jets, needle, clip position and if possible which type of block you're running as I believe there was an update. I'm about to fit my Keihin with Stic on my yz 125 after failing to get it to run right on my sx150 last yr. Any tips appreciated. Thanks.
@@johnsands146 Hi, I am running a 230 Main, 55 pilot, KEIHIN N3WJ Needle on the 4th clip, 7 block with the 1135 tube. I suggest you look up "Thumper talk stic it to your small bore" and read through the pages.
I think that it really comes down to personal opinion, I had a yz144 with a PC pipe force reeds and all. It had decent power but unless you want to be constantly at around 15,000 rpms then its not a good bike for you you have to keep it pinned CONSTANTLY. If you are a decent rider in my opinion it would be way better to get a 250 2t with much better torque compared to a 125 and not much heavier.
either you weigh 250 lbs or your bike is not doing well power wise. a 125 has good enough low end tourque without slipping the clutch. if your a good enough rider and your not a heavy rider. only people that hate on 125s are heavy riders or people who ride 450s expecting it to feel the same.
@@Bryan_327 So a rider at 120 to 130 lbs would not really want or need better low end torque with this bike in enduro, and hard enduro situations. Can you bring the front wheel up with ease, without having to hit the top revs, as in jumping over logs etc? I haven't had a 2t yet, but would so love the much simpler engine design and maintenance issues.
What size sprockets do you run? I have a stock 08 yz125 and i run 50/14 for more bottom end power. My god what a difference that was, the bike feels way more responsive and quick on rough trails.
@@filippo384 right, stock is 13 48, and 13 47 would be less bottom but more top speed, I just don't want some random person to see his comment and think that if they bought 14/50 sprockets, they would get more bottom.
@@Jake-rp9cv 14/50 in my humble opinion is a very balanced ratio for all my types of riding conditions. Great top speed and great low end power. If you’re looking for all lower end power then 14/50 isn’t the way to go, so you’re correct but it’s a balanced ratio for me. (;
Would this bike be a good fit for my stature. I’m 5’6 110 pounds. I’m switching from a 4 stroke to a 2 stroke wanna know if this is a good 2 stroke bike to get
i'm 5'8 ans 125ish and if you want something lighter then a 125 is perfect, very light for us who arent very big. also recommend a ktm 150, great for a track and trails, with a bit more pep than a 125
@@baronarneson6951 yes, the 125's are way more than a 125, but they are definitely the most forgiveable incase of an accident. practice in open fields just managing the power band can help alot starting out
@@Cortex1325 I cant say much since I dont have experience with the bike. People say its fine for fast trails, but you probably want a kdx200 or a ktm200exc/xc since the extra tourqe makes them a lot easier to ride.

@@Cortex1325 Yes, yz125x is specifically made to be an offroad bike where the regular yz is made to motorcross. The x can do a little of everything honestly. Moto, trails, some light enduro, cross country racing, it can do it.
I had a stock 03 yz125 except for a larger rear sprocket. They were a blast to ride but you really had to stay on it and rev the shit out of it in anything technical. These trails are flat.
I think so, the bike teaches you great technique and is easy and cheap to work on. At 5’3 you’d likely need to grow into the bike quite a bit but they are light bikes.
@@aidancampbell2656 You should always use clutch regardless of up or down shift. Your still slamming gears which is unnecessary wear on the gears. If one of those teeth break, youll be having a fun time ripping that case apart just to evaluate the damage.
@@ncopp4358 on dirtbikes you can slow down in a more controlled manner with properly time clutch less down shifts and braking, sometime pullin the clutch in can make you gain speed in some situations
I’m 6’ tall, 190lbs, riding a YZ125X. It’s my first 2-stoke. Lower rpms can require a little clutch work to keep momentum/avert stalls on the trail in certain situations. Up top, it hauls the mail. Think Dr. Jekyll and Mr. Hyde. The 125 2-stroke doesn’t have the linear torque curve, engine braking, and weight of a 250 4-stroke. However, I find the 125 to be WAY more fun than any other dirt bike I’ve owned. In short, the 125 is plenty of bike for most adults 200lbs under.
Horrible trail bike. No low end power. 125 needs lots of work before being enduro ready. Just get a 300. I personally ride a 250 just cause I like riding a snappy bitch
