Hot Cams is an aftermarket dirt bike and ATV parts manufacturer helping riders change their OEM parts for extra durability and horsepower. The power within the dirt bike can always be increased with a variety of ways to do so. Hot Cams camshafts are popular for these reasons, providing many models of KTM, Husqvarna, Honda, Yamaha, Kawasaki, and Suzuki with upgraded internal engine components. These items can help with big bore bikes such as the KX450F, RMZ250, DRZ400 and so many more. These items are usually changed when performing a top-end rebuild and the cam chain replacement is also a good idea when opening the engine up to this extent. Hot Cams stage 1-3 upgrades increase peak torque and power either in the low, mid, or high-end rev range on your machine. Popular on the Honda CRF450R and CRF250R is the stage 2 kit for an overall mild increase in power for these motors.

We highly recommend checking and even replacing items such as your stock valve springs and jetting when installing these performance camshafts. Be sure to check out the range of valve shim kits for your dirt bike model as these engine parts can also help increase the power output of the stock motor configuration.
