For a conventional 750cc side-valve, the original primary drive or something of equal value is usually sufficient.
However, anyone who breathes more life into their 45" Flathead, to make it a bit sportier or possibly even to move it on the race track, will quickly push their 3-disc clutch to its limits — and beyond.
In any case, this Cannonball primary drive offers traction to the very end of a 750cc Flatty's tuneability. CNC-machined steel and aluminium components, 5 friction discs and a strong aluminium pressure plate with spring-loaded balls, which ensure perfect and smooth frictional connection, prove that the focus during production was on function, durability and quality. Clean disengagement and engagement, as well as adjustment, are a nice side effect of this.
Anyone who rides it knows what we are talking about. But surely people will also have fun with this drive if they don't have a start number instead of a light on the springer fork.
By the way, this primary drive is perfectly suited for hand clutch conversion, as the spring forces are comparatibly low. The result is a smooth, easy and precise clutch operation at the hand lever.Due to various circumstances (improper selection, installation and maintenance) and applications under which belt drives are used, W&W Cycles is not liable for damaged belts.
