Just bought my first 2016 Yammi 450FX with 2017 ST 120. The Bike is complete with thermostat, Hand-warmers, CR Intake, Rad Guards etc..... I've read good and bad reviews on the FX WR tranny and looked through many threads regarding this topic. Does anybody have any experience with gearing whether its front sprocket or Chain case and what has worked best in different snow conditions? It sounds like the 3rd gear is quite higher and not easily held on some hills. Any advice from someone with experience with these bikes in the snow would be greatly appreciated!
