Flywheel Assemblies


KTT Services

Both flywheels designs  are machined and assembled in a different way from Velocette standard design, using a 35mm diameter interference fit rather than the original Velocette of 26mm diameter. This 35mm design isolates the flywheel from  shock absorber and taper roller bearing forces preventing the drive  shaft from separating from the flywheel.

We produce these flywheels in a way that achieves truly excellent alignment results.

Balancing is now included in the price.
