Belt Drives - Use of a belt, instead of a chain, for primary drive offers many advantages including reduced vibration, lower maintenance, and less damage if a breakage occurs. Our English made belt drives feature hard anodized aluminum pulleys to minimize weight, a steel insert on the clutch pulley to reduce wear and a sealed bearing which allows the primary to be run dry, eliminating both clutch slippage from oil ruined clutch plates and a source of leaks. Use of an AT10 steel backed polyurethane belt provides greater strength than conventional belts and virtually eliminates any need for adjustment. The pulley ratios have been selected to minimize loads on the gearbox and increase the primary ratio 11%.

As this effectively raises the gearbox sprocket by approx. 2 teeth you may want to consider going to a smaller gearbox sprocket when fitting the belt drive. We also highly suggest fitting the Dual Anchor mount shown below.

• Commando 1969-74 -Includes two pulleys and a 32MM AT10 belt. The factory clutch center and plates from your clutch are retained to keep the cost down and ensure replacement parts are readily available. - #C300 - $419.00
  
  
• Commando 1969-74 - Race Only - Similar to the above kit but uses a different style, 40MM wide belt. Available on special order only - #C308
  
  
• Commando MK3 - Similar to our #C300 but modified to fit the MK3. If the electric start has been removed use - #C303 - $479.00
  For a MK3 with a working electric start use - #C303S - $519.00
  
  
• Dommie/Atlas - The best way to fit a belt drive to these models is to convert to a Commando clutch (a much better design than the original) and use a variation of our Commando belt drive. To mount a Commando clutch to the earlier gearboxes either the mainshaft must be changed to the later version or a modified Commando clutch center must be used. This special center is included in Kit 1 below and is available as a separate part.
  
  
• Kit #1 is for those with a worn out or no clutch. It includes modified Commando pulleys, a special 27MM belt to allow the retention of the original primary covers, plus all the parts needed to complete the conversion to a Commando clutch and fit it to the standard gearbox. - #A360 - $695.00
  
  
• Kit #2 is for racing only. It's composed of the Commando pulleys, modified clutch center and the correct length, full width 32MM belt. You must supply, or purchase, clutch plates, spring, etc. separately. - #A363 - $518.00
  
  
• Modified Commando Clutch Center The simplest and least expensive way to fit a Commando clutch to a Featherbed gearbox - #A361 - $99.50
  

Dual Anchor Gearbox Mount - Use of this double-sided, stainless steel unit to set the upper gearbox location eases alignment of belt drive pulleys and/or reduces gearbox movement under heavy loads. This part has been recently redesigned and although functionally the same no longer matches the current photo. Installation requires the removal of the inner primary cover and drilling of the drive side engine plate. When used on a featherbed model, the short section of chainguard attached to the factory inner primary cover blocks access to the drive side adjustment and must be removed. - #N302 - $87.00
