Good used fuel filler cap with key to suit 97 K1200RS; F650; G650; R Oil Heads. They do have some marks and light scratches on them which is normal for these items in used condition. Also suit most 8v R models. F650 and G650 models.
If unsure, please check the REAL OEM site to
make sure it is compatible with your bike.
These may have the OEM key or an aftermarket key. A lot of the time I have to get keys cut from an original to suit the different locks.
