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.

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.

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.

An ever popular way to customize rigid frame and 4-speed Big Twins is to install Sportster gas tanks. The hair in the soup, however, was that the original rear gas tank mounts had to be removed, which meant going back to your old tanks at a later date was complicated. And since good, uncut frames are getting really scarce, the Wrecking Crew felt the need for a good solution, so here it is. Tank tunnel and mounting brackets of these Sportster style gas tanks are designed to bolt right to your Big Twin frame with no drilling, cutting or welding whatsoever. All original brackets and tabs stay untouched and are used for mounting, so re-installing the stock tanks is a snap. The tank brackets hold the tank in a position so that the bottom line of the tank runs parallel to the ground, which sure looks cool.
