DescriptionThe whole story▼
The GSX-S750 uses a four derived from the GSX-R 750 K5, tuned for road use. Gilles lists the OFC-20-15, thread M20 x 1.5, for its oil filler.
Key Features
- Thread M20 x 1.5, head diameter 29.5 mm
- Hexagon socket plus the enclosed tool for opening and closing
- High-grade aircraft aluminium
- Fitted in a few seconds, according to Gilles
- Distinctive Gilles design
- No registration required, according to Gilles
Type WC50
The listing covers the GSX-S750 of 2017 to 2020.
A2 and beyond
Many were ridden in A2 form first, then opened up; the engine stays the same.
K5 heritage
The GSX-R 750 engine of 2005 was a benchmark in its class, and its road-tuned descendant in the GSX-S750 keeps much of that eager, free-revving character.
Blue
Blue suits the Suzuki colours.
Road Approval
No registration required, says Gilles, and no TÜV either: the OFC goes on the Suzuki GSX-S750 without an inspection and without any change to the papers.
Scope of Delivery
One oil filler cap with M20 x 1.5; the kit includes the four inserts and the opening tool.
Fitting
Clean the thread of the filler opening so no dirt falls into the engine, fit the OFC and tighten it with the tool. Check after the first ride that it is still tight and dry.
