DescriptionThe whole story▼

GU055 tops out Accossato's ring range for the CP001 and CP002 clip-ons at fork diameter 55, the widest fork tube the clamp is offered for. Like the smaller sizes, it is sold as the ring alone, to be fitted into an existing clamp rather than as part of a complete clip-on.

Key Features

  • Internal ring for CP001 and CP002 clip-ons
  • Sets fork diameter 55, the largest in the range
  • CNC-worked aluminium

Construction and Material Quality

GU055 is CNC-worked from aluminium to the same close tolerance as the smaller rings in the series, and is supplied without a tube or clamp body attached.

The Top of the Ring Range

Because 55 is the largest fork diameter Accossato lists a ring for in this clip-on family, GU055 is the part to check first if a fork measures toward the upper end of what the CP001 or CP002 clamp can take; a fork wider than this will need a different clip-on rather than a larger ring. As with the other sizes, the fork tube should be measured on the actual motorcycle rather than estimated.

Fitment and Compatibility

GU055 is a spare part rather than one tied to a specific motorcycle; it suits a CP001 or CP002 clip-on wherever the fork measures 55, once that has been confirmed.

Road Approval

GU055 is workshop equipment and needs no road-use approval on its own; the clip-on it is fitted into carries whatever approval status applies.

Scope of Delivery

One pair of GU055 rings, fork diameter 55, ring only.
