Hot Cams 98-00 WR 400 F/01-02 WR 426 F/98-99 YZ 400 F/00-02 YZ 426 F Exhaust Camshaft - Stage 1

Hot Cams is a well-known name for performance camshafts, and this Stage 1 exhaust camshaft is built to give your Yamaha WR or YZ a noticeable boost. Designed and dyno-proven right here in the USA, it uses advanced valvetrain software to make sure it performs reliably. This camshaft is intended to give you an improved power output, typically between 5-10%, without breaking the bank.

It’s CNC-machined from 8620 billet steel and then case hardened, which means it’s built for a precise fit and a durable lobe profile that can handle the demands of performance riding. You can choose from different stages, like this Stage 1, which is a good all-around option for improving low-end torque and overall response. Installation is straightforward, and you don't need to worry about sending in a core exchange.

This particular camshaft is for the 1998-2000 WR 400 F, 2001-2002 WR 426 F, 1998-1999 YZ 400 F, and 2000-2002 YZ 426 F models. Please note that this part is not CARB approved and cannot be shipped to California.
