Am I the only owner of the src950 who experience this unpleasantly loud howling sound that appears around 6500 rpm and continues up past 7600 rpm to completely diseappear by 8000 rpm? I believe it is an aerodynamic noise but I have no clue as to what is creating it.

Sweet!
Now I can estimate my upper RPM range by the howling noise....
Obviously you must have upgraded to something with a tachometer.
Yes, mine howls. I assume the root cause is the tires, although the howling sound might be resonating from who knows what/where.
Like all the other quirks of the SCR, I've grown accustomed to it.
So now when it quits howling I'll be worried!

I assumed that the noise was Yamaha's new audible tachometer!🤔

Almost certainly the tires, but if your SCR is getting up to 8000rpm, it’s probably also the engine beginning to explode!! (limiter would long have kicked in by then) :grin2:

Even with mods and a reflash on the ECU, power peaks and starts to drop off between 5,500-6,000 RPM.
According to my Yamaha dealer, the back cylinder shuts down and the rev limiter should be kicking in at 7,000rpm or so.
There isn't a real advantage to revving out the 950 that high, if it were even possible.

Something I noticed recently which I believe adds additional support to the theory that the tires are responsible for the howl many of us have reported - if I turn, the sound changes pitch and intensity. Has anyone else noticed this?

 

[bringenufgun]

its a harmonic howl emitted by the tires. try raising or lowering air pressure to lessen the howl.

Ooops!! What was I thinking of🤪
No tach just mph!! My bad but no apologies for entertaining you;-)
Seriously, just tire design then? Actually I have put 3.5 k miles on the odo and the howling sound has moved up slightly. Has anybody tried different tires?

Yes I have, the sounds goes away when turning then reappears. within the same speed range

Switched to Michelin Anakee IIIs. MUCH quieter!
Have run a few sets of these on my Super Tenere and really like 'em.

Does anyone know what's the widest rear tire that will fit without rubbing?

I have always been told it's safe to go up one tire size from stock.
That said, check out this graphic when considering putting a wider tire on a narrow rim.
(Please forgive the grammatical errors. I found these as-is online.)

Yeah, I’ve never thought it a good idea, myself - and what’s to gain? More grip? Doubtful...... Look like you have a nice, big fat rear tyre? Buy a V-Rod!

Thanks for the advice Eddie. BTW. Where did you get that "TYRE" chart from? Ben? You 2 in cahoots with each other? 🤔
I want to go wider just for aesthetics. Try to zoom in on THIS rear tire!

I Googled wide tire on a narrow rim or something like that. lol

Used to ride a 1989 Honda Transalp 600. I had a guy confront me in a WalMart parking lot late one night about how I had to put a "big, fat tar(sic)" on it or it wouldn't look right. I tried to explain that the Honda was a dual sport and it went right by him. "No, man. It needs a big fat tar. I like a big fat tar on my bike." I asked him what kind of motorcycle he had and he said he didn't own one (never had) but he repeated, "I like a big, fat tar on a bike."
His girlfriend looked at me apologetically.
:grin2:

Bhahaha. Another good story eddie.
I can picture it as if I was there. Except in my mind his girlfriend was living proof that he liked a "big fat tar".

Your garage door appears to be more narrow than that rig is wide. Does it take a stunt rider to park that thing in the garage?

Ha - you’ve not wanted a fat rear tyre since these boys were in fashion!! :grin2:
