DescriptionThe whole story▼
For the GSR750 of type WVC5, Gilles lists two oil filler caps: the OFC-20-15 with M20 x 1.5 thread and the OFC-20-25 with M20 x 2.5 thread. This product lets you choose between them.
Key Features
- Thread M20 x 1.5 or M20 x 2.5, as selected
- Distinctive Gilles design
- All four anodised colour inserts included
- Hexagon socket plus the enclosed tool for opening and closing
- High-grade aircraft aluminium
- No registration required, according to Gilles
Which one?
Both are listed for the same type, 2011 to 2015. Compare with the thread of your original cap or send us a photo before ordering, and we will help you choose.
What stays the same
Both caps have a 29.5 mm head, a hexagon socket, a tool and four anodised inserts.
Why two caps?
Gilles' list gives no explanation for the two threads on the same type, so the safest path is to check the original part. Tell us the thread or send a picture, and we will point you to the right variant.
Road Approval
Gilles marks the OFC as not requiring registration on the Suzuki GSR750. The cap replaces the original one, and nothing has to be entered in the vehicle documents.
Scope of Delivery
One oil filler cap with the thread you select; 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.
