Rigid Frames For 45" Engines

Single downtube rigid frames with Chopper-style necks that use a 1941–1969 four-speed trans-mission instead of the old three-speed unit. We designed a special engine sprocket (see below - must be purchased separately) for Big Twin dual row primary chains and positioned the transmission mounts so that the primary drive components and special Paughco covers from an early 74" Big Twin can be fitted to the bike. And for those who don’t want to deal with a wet clutch, we have a BDL belt drive unit instead (see below - must be purchased separately). Both frames have a 30° neck rake with 0" backbone stretch, 0" downtube stretch, and no gas tank mounts.

Engine Sprockets For 45" Frames

BDL Open Belt Drive Kit For 45" Engines

A 1½"-wide open belt drive kit for 45" motors installed in our frame. The front pulley has the correct taper for the 45" engine shaft, and the rear clutch assembly is a Big Twin 4-speed style.
