Hey There All, I wanted to start a new topic all about moding and accessories for the new 2012 Yamaha WR450F. Lets get some stuff going about these bikes so everyone can discuss and review add-ons, changes/adjustments/mods. To start i'd like to know if anyone has changed the front or rear sprockets on their bikes, what they changed to, and some reviewes on results. The canadian WR comes stock with 14/50. Im thinking about swtiching to a 13/53. Any thoughts?
