Belt tension

[Roadster Renovations]

Also, when tightening the axle, only tighten the nut. That will help to keep the setting in place. Ride in increasing distances after adjustment to make sure it tracks correct. Do not back up and check it, as this will not give an accurate read. Good Luck!

BRP TST Bulletin Belt Tension.jpg

THANKS for all the good discussion.
I am changing out my rear tire tomorrow on my 2013 ST. All the discussion has been for earlier models.
So...my in air belt tension should be between 202 and 236 it sounds like.
HAS anything changed with BRP or users since all this good info has been posted?
THANKS!

From what I've seen recently the numbers have been drastically reduced to something like 140-180.

Based on the technical service bulletin the range is about 140 to 236, whatever works to keep the vibration at a level and speed range that makes you happy.

Is that measured with the rear wheel off the ground?

Thanks

Yes. Off the ground with the swing arm hanging at max shock extension is the only way to know for certain you are in a consistently repeatable physical configuration, particularly bike to bike which is what the service manual has to address. The tension changes with swing arm movement so measuring it with the wheel on the ground can give varying readings depending on air pressure in the shock. I suppose if you released all the air out of the shock every time you measured the tension with the wheel on the ground you could get somewhat repeatable readings. Determine the method and tension that works for you and stick with it.

I read about the SmoothSpyder in this thread. Is that a recommended install regardless of vibration issues? Where do I get one? (I am a Newbie Ryder). 2010 RT SM5

Never felt the vibration with our 2011 SM5 RT. I wouldn't worry unless I just FELT the need to change something. Even with the 2015's we only have a minor "to us" vibe around the 75-78 mph range.

I concur... Ryde, eat, sleep...Repeat.

Greetings!

Thanks again for all the solid advice. I do not have an adjustable shock, so extending the shock to the end point will be a good reference point.

Changed out the rear tire and am waiting for the dealer to get in the o ring in.

Thanks again! Andy
