Liquid Performance Minibike Racing Coolant with LP3 is specially formulated for smaller race engines, specifically 50cc to 85cc motorcycles. The LP3 additive reduces heat, friction and internal engine wear in the closed loop cooling system. This helps to maintain horsepower while extending engine life. Its lower viscosity results in better coolant flow meaning less work for the smaller high revving engines and their water pumps. Liquid Performance Mini Bike Racing Coolant with LP3 is legal for all AMA sanctioned racing events.
