Kawasaki KLX300 High Pressure Radiator Cap

Kawasaki KLX300 High Pressure 2.0 Radiator Cap

This is a great mod for folks running their bikes in high temperature environments, at low speeds (especially in technical terrain), or seem to spend some extra time idling and stopping a lot.  The stock radiator cap from Kawasaki is about 1.1 bar (16 psi) and this cap is rated for 2.0 bar (28 psi) which allows the pressure to be higher in the cooling system - resulting in a higher boiling point and less chance of boil overs.

We have used these caps with great success on our 300R and also our KLX300 Dual Sport bikes.  These caps will raise the boiling point by 30+ degrees Fahrenheit, resulting in a much better margin for keeping the bike cool and virtually eliminating the possibility of hot spots in the cylinder causing localized boiling. 

This product fits the following Kawasaki motorcycles:
2020+ KLX300R Off-Road
2021+ KLX300 Dual Sport
2021+ KLX300 SuperMoto
