1. Works as advertised!
I've owned my 06 CBR 1000rr since new and have always had a GPS on it. Was always annoyed at the speedometer being off so much. Finally decided to correct it. STG is amazing to work with. The speedohealer was easy to install, installed while changing air filters, so no more tear down was required. Used their calculations and now my speedometer was accurate with my GPS @ 20,30,50,60 and 75. Shoulda bought years ago.
