High speed vibration

[spdmarine]

Hi folks. New owner in north Phoenix AZ - 2017 RTS. Loving it! I've read through pages of the RT section and noted several posts about belt vibration and tensioners (not sure if that's a word). Anyway, I've only put 200-is miles on mine so far, bought brand new, and I've stuck mostly to side roads in order to familiarize myself with handling, turning, braking, etc. During the few times (3x I can think of), when reaching freeway speeds, I notice both vibration and sound - both of which disappear if I drop speed below 73mph or so. Is that the belt tension issue or related to break-in? I'm varying RPMs as advised by my dealer, but haven't gone much over 4K RPMs, hence wondering. TIA! Sean

The vibration that you feel around the interstate speed of 75 is common to the longer belt/ 1330 engine platform. My 2015 RT still has it periodically and either I have become used to it or it lessened a little after I reduced the tension and both the belt and bike got a few more miles. Many have employed the BRP or other aftermarket tensioners with good results, and some of us have just more tolerance and learned to avoid that harmonic frequency.

Read up on the Do's and Don'ts and mainly just RYDE, RYDE, RYDE. Enjoy your new world of wind therapy!!

Congrats on the new RT!!
After living with that vibration since 2014 we sell a kit that will stop that based upon BRP's one for the F3. Ours uses a double bearing design and where they use plastic we use aluminum.

We will be there in December. Come meet a bunch of great people. See the thread about Surprise. If you want, we can install Doc’s belt tensioner. Meanwhile, ride it!

I run my belt of the loose side ( 170 lbs. Kritkit ) I have no Vibes ..... Mike

Yeah, but Mike, you don't tell them you weigh about a buck forty soaking wet....

... To the best of my knowledge ... BRP doesn't alter Belt tension specs based on Driver , or passenger weights .... I could be wrong ( it wouldn't be the first time ) .......... Mike

I'm not sure I'm up to adjusting belt tension, even though I have read the "Do's and Don't" and the Owner's Manual. In fact I read through that thread before I made my purchase. I'm guessing based on y'alls responses that the belt won't stretch or the vibration go away with time / miles. I'm happy enough to driver over 75-ish and make it go away, but will continue familiarizing myself with the machine by neighborhood and under-70 miles.

As for December: I'm IN! Let me know when and where please? I'm dying to meet other Spyder riders locally and learn all I can.
