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.

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.

Graf Stroker Pistons 45”/750cc Flathead

Admittedly the investment for a set of stroker flywheels is pretty hefty and you wouldn't crown this wonderful device with a set of inferior pistons, would you? The Wrecking Crew, for one, didn't want to gamble and had these special pistons made by the renowend German manufacturer Graf. Those guys supply the vintage and classic racing scene since decades and you can simply trust their material. And yes, they are more expensive than your average 45 piston but a seized or broken piston at full throttle is by far more costly, guaranteed. ...

Samwel WR Flathead Frames

Samwel WR Flathead Frames

For WR factory racers the MoCo made a special "Light Frame" with numerous lightening holes on forged parts and various brackets omitted to save weight. On the other hand two rear frame braces were added to increase stability and two tabs to accept the spiral springs for a small racing seat. Unlike the original counterpart this reproduction is built from sturdy steel and not from chrome-moly tubing, which was prone to break. Now you can build your authentic race bike with peace of mind. Dimensions and details exactly follow the factory counterpart.
