Yamaha extro's will not fit the stock '10 drive shaft. The Yamaha extro's fit on a larger drive shaft. You would need to purchase the shaft as well.If you are on a budget try running the stockers. Your riding style may allow you to get away with stock non extro drivers. My riding buddy runs a rtx tretched to 136 with a 1.75 bc and he has had no ratcheting issues. He rides lots of off trail as well. Track is to tight side of spec but not over tight. With the dupont slides he has had no slide wear issues. Don't be fooled thinking with extros you will be able to run your track crazy loose. It will rub the top of the tunnel badly. You can only really run them on the loose side of stock spec. I would try it and see.

Use the parts fiche and check the drive shaft P#', they are different.
