    Z900 heavy duty clutch springs

    Posted by Scott on Dec 19th 2020

    Not so much a problem with the OEM springs but as I added more power makers, clutch slippage at higher gears and rpm's began to occur. These springs looked like a winning solution for a reasonable price. So far, so good, clutch lever pressure feels slightly stiffer and the bike feels like its hooking up much better now though I must mention I replaced the clutch pack also so it's a combination of the two.

    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.
