Works great, moves a lot of air and plugged right into the power cable my 23 ec250 had sitting under the gas tank.

If your bike spews coolant on slow technical trails, your stock cap is probably letting go early. This higher pressure cap keeps the system sealed tighter so the water boils at a higher temp. Screwed right on the radiator top with no leaks, and kept the coolant in the bike during a hot ride. Cheap insurance against trail side boil overs.

Stronger than the one that come stock. It has better welds than OEM. That's why I got it and will also buy same for future. The seams are way stronger. It can take a hard impact with out damaging the structure of the aluminum
