    Great bang for the buck! Improves feel and shift quality. No more slippage from full throttle accelerations in 4th and 5th gear.

    Worked perfectly

    I ordered these as I have had an issue where my bike will drop out of gear during hard acceleration, usually in 5th.
    After installing the difference is night and day, I can now get to the redline in 5th and seems to pull harder in every gear in top revs.
    Well worth it.
