2021年4月20日 · Bought a brand new bike 2021 YZ125X October 1st 2020 from a dealership 3 hours away. My first legit motor bike ever. Had it delivered to us. It’s now been 6 months. It still runs fine but I’m starting to overthink and stress myself out over maintaining my bike. I’ve been changing the transmission...

2023年12月22日 · Picked up a 24 yz125x last week. So far this thing is awesome. I wanted a 125 to challenge and force me to become a better rider. It's holding up it's end of the bargain... 21 yz250fx comparison: The 125 is slow but it's so much more nimble in the trees. It's much happier putting around with the gf as well. On rocky hill climbs the 125 sucks.

2024年10月4日 · On my 2024 YZ125X I’m running the JD trail spec but using a 60 Pilot to get rid of the lean bog (recommended pilot is a 50). Bike runs really, really good. 185 main, 60 pilot, Red needle in 4th clip. This is in 75 degree weather and sea level. I tried the Gytr Y3 and Y4 needles and could not get the bike running in an acceptable tune on my 125X.

2020年4月26日 · Switching to a 2 stroke again. I was just wondering if there are any real differences between the yz125 and yz125X besides sprocket size, tires, and more bottom end power in the X. Oh and I mostly ride trails and fields with some smaller jumps. Thanks!

2020年6月5日 · Hi, I am doing the top end on my ‘19 Yz125x. The cylinder has the letter C at the back so do I put a C piston in it? I just ordered 2 C size pistons for the next two top ends. Will it be fine? Thanks!

2021年5月10日 · The yz125x has plenty of top end power, from my experience. Its powerband starts at a lower rpm which makes it easier to keep it in the powerband in trail situations. It has just a tiny bit less top end power of the yz125. At 160 pounds, it's sprung perfectly for me. You may want stiffer springs. The spring rates are the same on the yz125 vs ...

2022年2月22日 · Hey everyone, Picking up my YZ125 from the dealer soon. I’ve read everywhere that it’s jetted rich from factory. Also read that people have been moving more towards yz250 jetting standards to get this thing right. Instead of these setting being jumbled in general 2022 yz125 posts, I wanted to rea...

2020年6月10日 · As Dan mentions, the YZ125 and YZ125X stock jetting charts and suggestions are usually quite accurate and, great starting point to fine tune from. It shows the each progressive step on enriching the needle circuit by either needle clip position or different needle #'s. also explaining which circuit affects what part of the throttle range etc.

2021年6月13日 · For those of you with a YZ125X; if you are looking to modify the governor so the power valves open earlier try the governor spring from the YZ125. It opens the power valves about 1000 rpm earlier. It feels like a smoother transition getting on the pipe. My bike felt like it struggled to get on th...
