Facts

When it comes to belt drive systems you don’t want to make compromises, because dependability is what counts most here. The tried and tested BDL beltdrive systems range among the highest quality drive train products available for the Harley-Davidson aftermarket.

These are belt drive kits with 3” belts for open applications and kick start only bikes. They do not inlcude clutch and engine/transmission plate.

  • Belt drive by BDL
  • fits 4-speed Big Twin 1955-1984
  • open application
  • steel / aluminum / polyurethane / carbon fiber, 144 tooth belt
  • width: 3”
  • kickstart only
  • sprocket shaft type: splined
  • number of teeth: 47 x 76
  • gross weight: 5.26 kg

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.

Dry clutches generate noises when the clutch is disengaged. The noise level depends on condition and construction of the clutch plates. If the primary drive is run open (i.e. without primary housing), these noises can be heard.
