Wiseco 98-99 YZ400/98-00 WR400 Clutch Basket

If you're working on your 2001-2005 Yamaha YFM660R Raptor, the clutch basket is a critical piece that often takes a beating. Stock baskets are typically made from die-cast aluminum, which can wear down and develop notches pretty quickly under the stress of off-roading and racing. This Wiseco clutch basket is built to handle those tough conditions much better.

Wiseco makes these baskets in-house in the USA, starting with a forged aluminum material. Forging gives the metal a higher tensile strength compared to billet aluminum, making it more resistant to breaking. Then, it's hard-coat anodized and coated with Teflon. This treatment helps minimize wear on the basket itself and also contributes to smoother clutch engagement, so you get better control. It comes with the cushions, backing plate, and hardware you'll need to get it installed.

Because they're so confident in the durability of these baskets, Wiseco covers them with a lifetime warranty against notching and breaking.
