Dude,I have a sick Yz 125 it's 2001 two stroke but,it was a team yamaha bike and is race ready with lot's of extra goodys!It has a bore kit on it with a sleeved cylinder so if you blow the piston and rings you won't crack the cylinder and have to replace it the worst case scenario you replace the sleeve.It is 19 cc's over and geared for the track!Never raced it was a practice bike to a pro rider before i aquired it!I'm asking 1800$but,will except a reasonable offer.This bike would be able to cmpete with aanything on the track now you don't need the clutch to do wheelies it has a lot of ****!
