Hello !


Switchback 800 with a 144" * 15" * 1,25" track and 9T driver.

Chain case Ratio : 1,65

Riding height : 400 - 900 Meters

My engine have some problems to pull this gearing in heavy spring snow under hard/heavy load.


To me it seems that most trail riders running 1,7 - 1,8 ratio, Or ?


Some people have told me to use as big bottom gear as possible...
Any benefits ?



HELP !

if i got the math right, you are running a 25 top and a 41 bottom? id say personally id run more of a 23/42 or a 23/43 range. it depends on what your want your top speed to be
