Use my K only for long trips but possibly like many others feel that the gearing is too low. It's doing 4400rpm at 100kms per hr.
There's a "Cycleworld K100" page on the web and it says the rpm at 60mph is 3720 with a final 4.71 ratio.
This sounds much better and so I'm wondering if the about diff option talked about in the Dec 1983 copy of "The Classic Motorcycle" (british) ever became available.
Bike is a 1983 RS (engine no. 104EA39832203) and I can't see any marking on the casing to indicate present ratio.
