WEM2 and WEM3

The listing covers the GSX-8S from 2023.

Naked engine

On the naked 8S, the engine side is in full view, and a coloured insert shows.

A new engine family

The 776 cc twin also powers the GSX-8R, the V-Strom 800 and the new 8T models, all with the same M20 x 1.5 filler in Gilles' list.

Road Approval

No registration required, says Gilles, and no TÜV either: the OFC goes on the Suzuki GSX-8S without an inspection and without any change to the papers.

Scope of Delivery

One Gilles OFC oil filler cap (M20 x 1.5), all four anodised colour inserts and the tool for opening and closing.

Fitting

Fit the insert you prefer, screw the cap in and tighten it with the Gilles tool. Keep the tool with your on-board kit if you top up oil on the road.
