  • Tusk Clutch Kit

    Paul in OH

    Tusk for the win. Again.

    Tusk brand clutches perform as well as any other I've used. Just because it costs more doesn't always mean it's better.

  • Tusk Clutch Kit With Heavy Duty Springs

    Gabe in WI

    No more clutch slipping

    I put this in my 1993 yamaha yz250 that had a slipping clutch. I have roughly 80 hrs on the clutch right now, I don't "power shift" through the gears, but I do pop the clutch to pull wheelies in 1st, 2nd, 3rd, and 4th basically every ride, this clutch locks up quick and has been holding up great. Clutch pull is obviously going to be a bit tough, but I'm used to old cable style clutches so it doesn't bother me none. Overall been holding up good for me!!

  • Wiseco Piston Kit

    Lawrence in AZ

    Very good piston kit from Wiseco.

    I've always had good luck with the Wiseco pro light piston kit for my 2017 YZ250. The price is right and my wife loves the purple velvet piston pouch. Just remember to get the stock piston pin, cause the kit don't come with one. I would recommend this product too others.

    Leaders slipping away? Try new clutch springs

    EBC products have always been good. Let's hope they stay that way. The clutch springs are great for adjusting clutch pressure & feel. Mix & match- have a great ride!
