Nice gas cap

Purchased after getting water in my tank probably from that stupid stock hose they put on a stock cap. It is a gas cap and the balck cap looked good, not alot to say about a gas cap?

Great Purchase

Bought this for my 2006 SE blaster,Tanium. looks awesome on the black tank, read review, Mine does NOT leak, and the vent tube after I put it on, it stayed on. Just looks amazing.

Looks great

Along with new red bars, this (red) gas cap gives my Raptor Rosie a clean look. She's all done up with a fresh coat of lipstick. Mmmm Mmm

Very Cool Cap

This gas cap is great the one way valve eliminates the long vent hose. If that wasent enough it also makes the tank look refined. I love the look of the aluminum as well!!


Doesn't fit good, leaks and for the money you would think this product would be better, the only thing that's good about this gas cap was the look!!!

Rock gas cap

They gave this gas cap the right name. Rock solid and well worth the money. throw one on your bike and forget its there.

Don't buy

I bought this cap for my 03 crf 450 and it leaks gas but my brother tried it on his 07 crf 450 and it doesn't leak.

Don't waste your money on this!

Looks good and screws on good, but leaks fuel all over out of the vent hose. Over all would'nt recommend buying this product to anybody.

Will this cap fit on a Clark USA gas tank?

Unfortunately it will not fit. With Clarke gas tanks, you have to use a Clarke gas cap. If you need a stock replacement gas cap for your Clarke tank, give us a call. If you are looking for an aluminum one, you can purchase one directly from Clarke here:
