Radiator cap

This is a must if running wide open in sand. Especially if your running a little hot. Helps keep the coolent in. Used to lose just below the top fins worth of fluid in a moto under those conditions, and now I don’t.

Perfect replacement for stock

Perfect seal and can withstand higher temps than the stock cap.

CV4 radiator cap

Installed on a 2003 RM125, holds pressure alot better and reduces boil-over. Looks decent.

Well, it's inexpensive.

They look really nice in the photo, but looks like a China part in your hand. Hold it up to your OEM cap and you'll see the metal is about 2/3 the thickness. Such a small part that I can't imagine they're really saving anything by making it thinner. It's not a cell phone, they're not selling ten million of them, why not make it nice? I dunno, it's fine, it seems to work, but it's not exactly a confidence inspiring part.
