Racing Pro 4T engine oils are available in two viscosities — 0w40 and 15w50.

Motorex says the 0w40 viscosity delivers “top horsepower” in Japanese sportbike and motocross engines and has been tested to add as much as 2 hp in a 450cc motocross race engine.

Both viscosities are available in 1-, 4-, and 25-liter sizes.
