Description
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.

  • Belt drive by BDL
  • for open or closed applications
  • fits Big Twin 1936-1954
  • steel / aluminum / polyurethane / carbon fiber, 132 tooth belt
  • width: 1-1/2”
  • kickstart only
  • sprocket shaft type: tapered
  • pitch: 8 mm
  • number of teeth: 39 x 62
  • gross weight: 3.71 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.

The Tamer

The Tamer

The »Tamer« solves a problem that Harley riders know since 1941. The design of the stock clutch hub bearing permits lateral movement of the clutch shell. This causes the clutch to drag slightly when disengaged, which is annoying in heavy city traffic. The easy-to-install Tamer Clutch Retainer holds the clutch shell in the proper position so it won't move when the clutch is disengaged. This also yields reduced gear clash and easier shifting.

Clutch Retainer

Clutch Retainer

This retainer is designed to hold the clutch shell in place, permitting more clearance between the clutch discs, and allowing complete and positive disengagement of the spinning discs. Especially recommended in combination with our Big Fix clutch bearing on bikes with belt drives.
