Vibration / Buzz from Triple Tree Area

[ngr2001]

Just wondering if I am the only one who ever experiences a minor yet annoyingly detectable vibration / buzz coming from around the triple tree area, only seems to happen at low speed / rpm typically in 2nd gear. Goes away and or cant hear / feel it at higher rpm. I do have a ram mount triple tree fork stem adapter in place, highly doubt that's the issue though.

Anyone else.

Removing it and see. Mine would make a weird vibration through the handlebars when I had my phone mounted (i had the anti vibration adapter thing too)

All normal. The busa tends to vibrate the worst at about 4K rpm no matter the gear you're in. If you cruise at that rpm or there about, your hand will go numb. Try not to cruise in the rpm range.

I got a GSXR1000 as well, does not have the same issue, I figured a Busa would have less vibration.

All three versions of Busa's that I had-have had the same vibration at the same RPM.

Yeah this. It's not the triple t, it's the RPM at which the balance shaft can't cancel anymore.

Mine also vibrates around that RPM. Good thing it's not just mine. I was subconsciously bummed out about it!

Dang ok, welp, coming from a liter bike more vibration was not what I was expecting. Bike is buttery smooth elsewise

You could try adjusting the balance shaft . . . c10 has a vid on doing just that,

Reducing engine vibrations (felt at cruise ) video | Gen 2 Busa Information

I made a more detailed video for the org after doing @SSGT_B gen 1 yesterday . Note Gen 1 is easier than a gen 2 due to no fairing mount on the engine . Due to Gen 2 you will need a small 5 mm allen wrench ( Hex pro is seen in video ) to loosen the pinch bolt . 7 foot pounds tq is all that is...

Or maybe bar weights to change their resonance. But it could make them buzz at another RPM.

It's a buzzy 'ol beastie for sure...

I've experienced a similar buzz on a GSXR 1K I rode during a Suzuki event at the track even though my personal GSXR didn't have the buzz...it was kind of odd...

Although I read that pretty much all Hayabusas have this buzz....

Yes, my '99 Bus has vibration at 4000rpm, it's just a characteristic of the engine for sure . . . but . .tuning the balance shaft can improve it and minimise the vibes.

Yup 4300

Our speed limit in NZ IS 100kmh, which is 3800rpm with standard gearing, just under the dreaded 4000rpm vibe range… but who rides at speed limits anyway
