New SR/S - noises
« on: August 12, 2021, 06:36:41 AM »

Despite my local dealer’s best efforts, I have finally received by SR/S. What a lovely looking bike! It is definitely much more pleasant to ride on the freeway at >55mph that the SR I had previously.

One thing: I definitely notice a lot more engine noise compared to the SR. When starting off, there is an extra layer of noise on top of the familiar engine whine. Is that usual? I’m worried that the brake disk is warped or something. The noise disappears above 20mph. A harmonic with the fairing perhaps? A slow speed there’s definitely a little shhhh-shhhh noise in time with the wheel rotation. Should I put this down to new brakes bedding in?

No expert here since I also am new to the SR/S.  My 2021 was also noisy for the first couple of hundred miles, then it quieted down. After that I hardly noticed the noise when wearing earplugs. I have been told that a lot of the noise comes from the belt.  I later damaged the belt and elected to replace it even though it was still working and the noise came back and is now slowly going away.  I figure approximately  5 to 6 hundred miles for the belt to break in. I also had a bit of vibration in the beginning, but that also went away. Hope that helps.

Do not think that it would be your brake disks, from my experience on other bikes you would feel it when apply the brakes.

I also get the "slow speed ... shhhh-shhhh noise in time with the wheel rotation."
It doesn't go away.
My guess is it's a future warped rotor (you've probably seen the threads and replacement parts posted by NervEasy).

On "When starting off, there is an extra layer of noise on top of the familiar engine whine";

Are you talking about the warble noise, that starts, upon first rotation of the throttle (after just arming the bike)?
It will be silent upon arming and then warble, upon the first twitch of throttle.
Try it, without actually rolling the bike (then you'll hear it more).

I wonder if its a Pedestrian Alert System?

Thanks - it does seem to be mostly a case of new bike paranoia - the noises are diminishing already. There are some resonant frequency issues - I can feel a buzz in the foot pegs at a specific very low speed. Not really an issue.

More observations compared to my SR..

1. The mirrors are superb. Compared to the SR which showed nothing but my stomach, these are easily on a par with my BMW R1150RT.

2. The foot peg position is comfortable - until I put my feet down. I need to get used to putting them in a different place to avoid stabbing myself.

3. Mode / Indicator switch placement is something I have now gotten used to.

4. The seat is not the most comfortable seat I have sat on. Either it or my butt needs broken in.

Overall I like it a lot. I think I'll grow to like it even more, to be honest. Looking forward to putting some more miles on it.

I do think it's overpriced; compared to the fit and finish of the previous bikes I've owned, I'd say it was $5K to $10K too expensive. However, that doesn't take into account economics of scale, US Tax incentives, smaller marker, different energy system, early adopter stastus (still even after all these years, owning an electric bikes feels like an early adopter situation). I'm happy to be in a situation to be able to help support Zero and green vehicles.

Oh, and my dealer.. boy.

It's not advisable to put your feet down while riding.

I guess this response is a joke  ;D  There's lots of daily commute situations to ride with "the landing gear out" in motion, yet I think the intent was when coming to a rest not while riding in motion.

Glad for the OP that SR/S is panning out to be a good experience.
