Ok, just a question. I have a 2014 RTS. Been on highways, back roads, up mountians, down mountians, rear wheel has been off and tire changed. never ever have I felt unacceptable belt vibrations. Just curious as to what could be different between your bikes and mine, that you need a belt tensioner.

Some ryders don't experience it at first. Has a lot to do with number of miles on the byke, load ratio, belt tension and alignment. Our 14 RT didn't start out that way either. We had about 8k on it and it started a little vibration on the interstate, especially going down a slight incline. Others have reported different scenarios, so it varies by byke.
Bottom line, if you don't need it, don't worry about it until you do. You will be able to tell if/when it starts. You will feel it in the pegs or floorboard....

Vibration difference between same model Spyders

Ok, just a question. I have a 2014 RTS. Been on highways, back roads, up mountians, down mountians, rear wheel has been off and tire changed. never ever have I felt unacceptable belt vibrations. Just curious as to what could be different between your bikes and mine, that you need a belt tensioner.

I have said all along that the vibration is coming from the engine & the belt just transfers that vibration. Those with vibration can park their Spyder in neutral --rev the engine in the 3200-3800 range & still feel the vibration when the belt isn't moving.

You got lucky--your engine is correctly balanced the equivalent of a blue printed engine--BRP parts have a wide tolerance in variation--In your case ---BRP picked same dimension pistons & rods -etc.
