No worries man. I´ve found that MOST bikes in top gear are close to 1:1 in the gear ratios. In a nutshell your speedo and tach with be parallel meaning; for every 1000 rpm you go up,the speedometer will go up another 10 m.p.h. or k.p.h EG: 40mph=4000 rpm, 50 mph=5000 rpm ect..Ya know what I mean now? CX´s are known for reving at speed. I always swore that CX´s should have had a 6th gear to knock the r.p.m.´s down. Good luck man, hope that helps ya! ;D
