I just picked up an 08 YZ125 recently and had it out for my first real spring ride with a fresh clutch and good traction. This is my first 125 and it scares the living Jesus out of me I went 12/48 gearing without riding it with the stock 13/48. The thing is like a raped ape. I'm gonna switch back to stock gearing, hopefully it stretches the gear out a little and takes the light switch feel away. Like I said, I'm new to 125's but not bikes, I run a YZ250 and KTM 350SXF. It was a bit of a handful in some of the fast chopped up single track I rode today.
