DescriptionThe whole story▼

An R1 prepared for racing needs a guard in front of the rear sprocket. The TG rear sprocket guard for the Yamaha R1 from 2015 is Gilles' version of this shark fin, mounted under the swingarm.

Key Features

  • Mounts under the swingarm, in front of the rear sprocket
  • Keeps feet and hands away from chain and sprocket
  • Built for racing, where a sprocket guard is required
  • Black with the Gilles logo
  • For racing and track use; no registration required per Gilles

Racing requirement

Most racing series and many track-day organisers require a sprocket guard. Gilles states that this part is homologated for racing and track use.

Part of a Gilles package

One product photo shows the guard on a track bike together with other Gilles parts: axle protectors, chain adjusters and paddock stand adapters.

Check the clearance

After fitting, turn the rear wheel by hand and check that the chain runs freely past the guard with the suspension compressed and extended. A chain adjusted too slack can touch a guard that is mounted close to the sprocket.

Road Approval

Gilles states that this sprocket guard is homologated for racing and track use, where a guard in front of the rear sprocket is required, and lists it as not requiring registration. On the Yamaha R1 it is an addition to the standard chain guard.

Scope of Delivery
