Well it just happened to us today.Riding along at 68 mph ,heard a clang noise and no more tranny.Bike wont shift at all.Had to call a tow truck and $325 later we are back at the campground.After talking to friends who have had this happen and reading the posts here I have a few quistions. I dont mind doing my own work but from what I have been reading , after fixing the bike all the fix is just putting the crap back the way it was, is there not a better sprocket ,better setup than stock.Why is can am getting away with this?as you can tell I am a bit pissed,we just left for a 3 month vacation and now no bike. Been riding and working on bikes for over 30 years,all kind of bikes and never was there not a better aftermarket part I could not get to make something better. as I said I dont mind the work,but to replace with the same crap just seems stupid. Thnks for letting me vent.
