Re: Rear Rack Fuel Tank
Nice, that's a Coyote-Gear tank. They have a website and you can buy direct from them. I didn't know they also sell on eBay.
I put a 6x12" on my bike last year and my brother put a 4x8" on his a few months ago.
Definitely high quality tanks, but be careful of the gas cap - it breaks easily.
Many automotive gas caps do fit tho, including lockers!
