I have a 2015 F3 with about 32,000 miles on it. I bought it used from the wife of the former owner who passed away. I've had it for about 3 months and it had a bad vibration in the handlebars and floor boards from about 60mph and on up. I took it to the dealer and they rebalanced the front wheels. This helped slightly but didn't solve the problem so I took it back, next they rebalanced the rear wheel, that also helped slightly but didn't solve the problem. I took it back and suggested there may be something wrong with the front tires. They had the bike for almost 3 weeks and finally got permission from CanAm to take a set of front wheels off a new Spyder on their showroom floor. They said that made a tremendous difference so the tires must have been out of round, though they looked brand new. I replaced the front tires with the Kendas, again this helped but the vibration was still noticeable so I ordered the belt tensioner from LaMonster and had the dealer install it. Once agian the vibration was reduced but not eliminated, I thought for sure that would solve the problem so was disappointed. I have no idea what else to try but would appreciate any suggestions that any one has. Unless I have some new info I don't see any reason to take it back to the dealer, they don't seem to have any ideas. Any one have any ideas??!!
Its taken me two years to get my RTL to a satisfactory state on a major scale.
1. Got rid of the OEM tyres, it surprised me just how much vibration they caused.
2. Fitted a belt Tensioner/Dampener, this made a huge difference in the 110 to 130k/hr range, two up and towing.
To a lesser extent
3 Fitted magic mirrors and these took away a lot of the distortion in the mirrors at highway speeds
4 replaced the Suspension with Aftermarket units, now it is less annoying on corrugated roads.
With regards to item 2, consider one that fits to the "return side" of the belt as opposed to the majority that fit to the load side of the belt. Mine fits to the load side, and does well until I hit a bump and you feel the belt bouncing for a while until it gets settled again.
