Free Spirits Belt Drive Conversion – Triumph Bobber, Bobber Black and Speedmaster




Belt transmission primarily made to reduce “loss of power” and to eliminate completely maintenance (no cleaning, no greasing) – more time to ride!

Suitable for:

  • Triumph Bobber
  • Triumph Bobber Black
  • Triumph Speedmaster 1200

Ratio slightly shorter compare to the original.

  • 61 teeth alloy pulley – available in Black or Silver
  • 27 teeth nickel plate pinion
  • 136 teeth belt

Compatible with OEM chain guard.

ATTENTION! This is Not a Bolt-in kit! Due to a bracket which prevent us fitting the belt, it’s necessary to cut and substitute it, with our removable one, see instruction on pages 9,10,12,13,14.

Quick and easy to mount, completely reversible.

Spare parts available.
