We’re at it again with designing and manufacturing more innovative pieces for our motorcycles, which helps make these motorcycles some of the most desired machines on the planet. This time it’s a new primary drive system, originally thought up and made for our winning Discovery Channel Biker Build-Off chopper. Keeping with the mindset of making form and function coexisting, this primary is built tough and reliable along with a very sleek, new generation styled aesthetics with a cool BBC branded inspection cover. BBC states that this primary drive is approximately 200% stronger than most other manufacturer’s primaries with its machined forged aluminum inner and outer cases. The dense aluminum material makes for a unit that does not flex under heavy torque, and absorbs most engine vibration. Another great attribute that sets this primary drive ahead of the curve is the triple seal design on the main shaft, as opposed to an industry standard single seal, insuring virtually no leaks. The starter motor shaft accessory plate is removable for an easy starter change-out. The internals utilize an easy-to-replace standard type clutch basket and a compensating sprocket for a smooth power transfer. This BBC primary comes as a high polish finish with all necessary hardware.
