This tank cap for BMW motorcycles from Motone is made from solid 6061t aluminum for a perfect look on your bike. The accessory is ready to be mounted on the motorcycle simply by screwing it on without any modifications.
To allow for a better grip, the side of the tank cap is knurled. The lower threaded part features a system of 3 spring valves connected to 3 air vents at the top of the cap to eliminate internal pressure in the tank.
The Tank Cap Moto BMW R Series includes a gasoline-resistant o-ring seal to be placed on top of the threading.
