I need some advice on the KTM EXC-450 6-Sped Tranny in comparison to the WR-450 Tranny. I have never riden a 6 speed anything. Sounds like knitting to me. Knit one Pearl Two. Kind of like gear grinding a Semi. The Yamaha and KTM websites are useless in getting good specs. So the KTM has got a 6th gear. How tall does the 6th gear get you compared to a WR-5th? How short is 1st? Are the ratios the same between the two bikes regarding 1st = 1st ? Is the WR-5th = EXC-6th?? Or does the EXC-6th get you taller than the WR-5th. Bottom line is will the EXC-450 in 6th give you more top end speed than a WR-450 5th?
