Excellent product.
Well engendered, easy to install. Waiting for good weather to try out.

Great investment
I was having this annoying belt shake when riding on the highway at 55mph and higher and also going uphill. I was referred to Slingmods for this belt tensioner and I must say that I am very pleased. It was a quick and easy install and now my highway rides are much more enjoyable since the belt shake is about 95% gone. I would highly recommend purchasing one for your Spyser.

Tensioner solves problem
I was experiencing a serious vibration that at first I thought was tires out of balance. Usually occurring at 70-80 mph. After remounting and rebalancing tires, still had vibration. It was after reading others reviews that convinced me to give the tensioner a try. The can am tech was not totally supportive, but I went ahead anyway. At present having installed the tensioner the machine is exceptionally smooth and tensioner totally eliminated vibrations. Good Purchase. Tech thought would at noise, but did not.

Belt Roller Tensioner
The installation instructions should tell you to mount and align parallel to the belt, not the frame brace or swing arm. It did cure the vibration I would experience when slightly letting off power, especially when towing my Spyder RT22 trailer. Unfortunately my drive belt is "ribbed" on the back side and causes a hum at low speeds ( under 25mph). Overall it is a quality product and works fine.
