I have a yamaha yz 125 and I was driving down the road and all of a sudden my back tire locked up. I think something is wrong with my gears because I can't shift or anything, the engine runs fine like I can pull the clutch in and start it up but it just won't shift or move. What do you think the problems is and how do I fix it.

Does anybody no where to get a service manual for a yamaha yz 125.

Haha what year bike?? I have the same problem.. same thing happened to me riding down the road she locks up and still runs like a dream though but anyway it sounds the same as mine and right now I know that a shift fork bent and I don't have 2-4 gears and as of right now I'm looking at around 400 to 500 dollars in repair that's with shop pay also
