Belt Drive Kits

For a conventional 750cc side-valve, the original primary drive or something of equal value is usually sufficient.
However if you consider to increase the power of your 750cc engine and might even takle a spin on the race track, your 3-disc clutch will probably not be the appropriate companion.
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 sturdy aluminium pressure plate with spring-loaded steelballs assure a smooth frictional connection. The high quality of all components, perfect function and durability are the main aspects that have been taken care of while creating this product. Clean disengagement, engagement such as easy adjustment are nice side effects of this.
Anyone who rides it knows what we are talking about. But surely people will also enjoy this drive if they don't have a start number on their 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.

Complete, smooth running belt drive kits for 45" models which eliminate the need for primary lubrication and thus the inevitable spot of oil underneath your scoot. All versions fit under the original chain guard for an easy installation and use the original discs, springs and pressure plate.
