  • Tusk Competition Clutch Kit with Heavy Duty Springs

    Tusk Competition Clutch Kit with Heavy Duty Springs

    jacob in PA

    Very nice

    Installed into my 2006 ktm 105, my basket is a bit notched but these plates work great. was worried bc oem and other aftermarket plates were 100$+ but I pulled the trigger on the tusk kit and glad I did. Was able to buy other parts I needed with the money I saved.

  • Rekluse RadiusX Clutch

    Rekluse RadiusX Clutch

    Christian in VA

    Good buy

    Good buy. A little expensive and rekluse went up in price. The installation instructions are little bit conflicting with the videos they recommend watching in the instructions. One negative note I will make is, you have to adjust the free play before every ride. For the money you spend is a lot of adjustment to make. Also one thing to note, is to buy the rekluse slave guard. It comes with the hole in center and you can make the adjustments for the free play on hydraulic clutches. If you don’t have it you won’t be able to adjust your free play.

    Tusk Clutch Spring Set

    chris in WI

    Works great

    Used as part of a clutch upgrade on my 2003 LTZ 400. No issue with the install. It did give the clutch a little heavier feel, but not bad at all.
