The speedometer kit replaces the stock speedometer gearbox and drive ring located in the front wheel.  This not only reduces weight for less un-sprung mass, it keeps the bearings sealed and clean for road racing or custom electronic speedometer conversions.  Custom machined from 6061-T651 aircraft grade aluminum they are guaranteed to fit.  Dimensions are 32mm OD x 15mm ID x 28.65mm width.  The backplate measures 58.6mm diameter to fit up against the wheel bearing.

The speedometer spacer weighs approximately one ounce, or ten times less than the stock speedo gearbox and drive plate.  The spacer kit is guaranteed to fit and reduce un-sprung mass and will fit ALL of the following models:

• CB350
• CB400F
• CB450
• CL450
  
• CB500
• CB550
• CB750

May fit other models, please check the dimensions above with the dimensions of your speedometer gearbox.  Please contact us with any questions.
