I've got an o3 ZX6RR and am just wondering if there are any differences with the gauges from a RR and a 636. Mine didn't have one so I'm looking around for one. Have found one for a 636 but just want to make sure there are no differences. I have read there is a lap counter on the RR. Didn't know if the 636 has it or not. Any info would be helpful. Thanks.
