with LP3 is specially formulated for smaller race engines, specifically 50cc to 85cc motorcycles. The benefits of the LP3 additive reduces heat, friction, and internal engine wear in the closed loop cooling system. This helps to maintain horsepower and reduce internal engine wear 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 while eliminating cavitation. Liquid Performance Mini Bike Racing Coolant with LP3 is legal for all AMA sanctioned off road racing events. Pre-mixed with deionized water and ready to use. Propylene glycol based, phosphate free, virtually non-toxic and biodegradable. Available in 64 oz. and 1 gallon bottles.
