Cannonball WR Style Gas Tanks
Racing style gas tanks for Big Twins shaped after the legendary WR model tanks of the late forties and early fifties. The beautiful narrow design and excellent European craftsmanship really stand out in the crowd. Each set is completely handmade by experts. Unlike the original WR pattern these tanks are supposed to contain gas in both halves.
To avoid an unsightly gap between engine and gas tanks our WR Style tanks are model specific and sit close to the motor which looks purpose-built instead of universal.

Lowbrow WX Split Gas Tanks
Lowbrow WX Split Gas Tanks
The WX Gas Tanks are directly influenced by the Harley-Davidson WR factory racer, a 45”/750 cc Flathead designed to dominate the flat tracks and road courses in America. They feature an innovative design which allows them to be fitted to stock 4-speed Big Twin frames from 1936-1984. The split and narrowed look with a slim profile is the perfect match to a fast and nimble motorcycle, from Knucklehead Bobber, Panhead Chopper or Shovelhead Cafe Racer.

Bates Beefy Body
Bates Beefy Body
In the 1970s motorcycle designers became more and more spirited and the familiar lines and appearance of two-wheelers were radically remodeled. Daring tank and seat combinations, mostly realized in fiber glass, soon freshened the bike scene and some ideas were even picked up by large manufacturers. The Beefy Body derives from a design by the legendary Californian company Tracy, which was an industry leader in this field back then. Gas tank, seat, side panels and rear fender form a single unit and completely transform the bike. Just add a fancy paint job and your scoot will stand out in the crowd, guaranteed. The whole body is made from fiber glass covered with a VE Flex gelcoat, which provides a smooth and clean surface for painting. The original fender struts can be omitted and the Beefy Body bolts directly to the frame. A seat base plate for building your own custom seat comes with it.

Split type fuel tanks for 4-speed Big Twins 1936-1984

Two tabs are welded on at the top and bottom of the front section. The screws that go through these tabs need the appropriate counter support on the frame. In addition, each half of the tank has a welded thread about eight inches from the rear end, where another mounting screw is attached that goes through the bracket of the saddle T-bracket. The insides of the tanks are shaped so that they fit into the spaces between the frame tubes.

Take off split tanks

The two sides of the tank are connected below the frame neck by a piece of hose. Before removing the tank, the tank must be drained to avoid major spills. An alternative to pumping out is, of course, a connecting line with quick-release coupling.

Single-piece gas tanks, FX style

The first FX models in 1971 and 1972 also had the tanks from the FLH. To differentiate the model series, the 1973 FX was given a one-piece tank whose shape and curvature was reminiscent of the first Sportster tanks. The tank tunnel was shaped in such a way that the tank fitted a 4-speed frame with a seat cross holder and cast dashboard mount without cutting off any part or bracket. The tank was hooked in at the front behind the steering head, centered on an enormous rubber block and held at the rear by a spring. Original FX tanks are very rare, especially in good condition. Our Quickbob tanks make use of this extremely well-thought-out mounting system and also have a few liters more capacity than the originals. Fuel spill during removal is avoided by the design. If you're fed up with the rigid bracket breaks of the split tanks, here is your vibration-resistant alternative. The only thing you will have to forego is a dashboard with a Fatbob speedometer.
