CV4 High Pressure Radiator Cap
Ethan in WA
Good product
Worked just as described. Doesn't leak. Spring is strong so the bike doesn't spray coolant before its actually overheating

Mylers Aluminum Radiator
Bobby in NV
Bad quality control and design
Pretty bad fitment and quality control. The brackets and some of the fins where bent straight out the box. I had to dent my pipe just to make the radiator fit.

Enduro Engineering Radiator Braces
Bobby in NV
Do not buy
It has horrible fitment, I had to dent my pipe and cut the braces down so it would fit. It also didn't feel very solid in the bike.
