Upsizing your front wheel to a full 21” unit is the upgrade that delivers a completely custom look British Customs has developed a 3.5 x 21” Front Wheel Conversion Kit that allows for a 21” front rim to be laced to a factory Bonneville or Thruxton hub. While making your bike stand out and become the envy of every rider in your pack, the larger wheel also improves ride quality by sucking up and rolling over any bumps along the road. The BC Conversion Kit includes a 21” chrome plated rim with polished steel spokes. These kits are made to order and will require additional processing time. Please be advised this can be as long as 4-6 weeks. NOTE: Front tire is not included. Front hub is not included. Kit does not work with non-spoke models. This Front Wheel Conversion Kit is a spoke and rim kit. The bigger wheel size may change the handling of your motorcycle and we recommend combining this kit with the proper rear shocks and suspension adjustment for optimum ride quality. Relocation of rectifier is recommended, please see British Customs Rectifier Relocation Kit.

What is the cost to have the rim laced and trued ?
Unfortunately we do not offer lacing/truing services. You will need to have you local shop do this for you.
