I know that your eyes immediately focused on this very unusual gas tank. I bet, a crowd pleaser… Don’t know how each of the 4 bombs was fabricated, but yes each contain gas with the reserve in the front and a fuel pump to help the bike do its sparking and ticking.
It’s a Harley Softail Twin Cam A with a preserved stock Harley engine but a 5-speed right side transmission to keep the bike balanced after installing a fat 280 mm rear wheel/tire. Frame rake is still stock 32-degree but is using a 6-degree raked triple tree with the Harley front end length kept intact because the bike was sharply lowered in the rear. Except the custom wheels and the hand made exhaust system, oil tank and fenders, almost all parts are still genuine Harley-Davidson. Built by a shop in Poland called BT Chopper. (photography H.
