Front end shake at 120

[el stumpo]

As I get more comfortable with the Busa, I'm starting to open her up a little more....

I've noticed at 120mph, the front starts to shake. Enough that I notice the DB windscreen shaking. Not a tank slapper, but is of concern especially if I start to take her faster....

Rock said to check my tuck. I took her out yesterday and concentrated on my tuck, but around 120 (I'm not staring at the speedo at that speed

the shake begins.

Ideas of things to check? Almost 7k miles. Stock front tire. Under 100, she's just fine. Front brakes and rotors do not show any unusual signs at slower speeds either.

TIA

Check to see that the front wheel is true..I had a bent rim which caused a nasty headshake

Front tire is probably cupped, out of balance or a combination of both.

That's an idea. Won't need a Busa then...

Be on the lookout in the 'for sale' section

I've seen 145 on my ZX1000R with my wife on the back, so I doubt that is it.

Yep, sound like you bought the wrong color Busa and  get nervous going over 119mph. The Silver and greyBusa  is the fastiest color.

I have a 02 all Black LE and she gets tighter the faster she goes,at 160 she is solid,you just got the wrong color,paint her

I agree with it being a tire issue. But I will also add that even though I have never had any sort of shake thus far, I upgraded my steering damper oil to a 30W and found her to be even more solid feeling than before. She never felt bad but as speed picked up you got a little more jittery in lane changes etc. This helped that.

I also agree the faster they go the tighter they seem to feel. 160 felt like a cruise rather than a strain.

shakes at 120... press on to 130 and up then... should smooth out...

Just playin... yea if you got 7k+ on your tires... you need new shoes!

 

[el stumpo]

Sloto200 - believe it or not, I tried that and it continued to shake

I think you're right. Baby needs new shoes.... Looking for them now.

Thanks for your help

New shoes and a new paint job to Silver and grey.

7,000 miles on the tire?!?!?! was that a typo?!?!? replace those worn out tires!!!

 

[frisbee]

Check the tire and rim also check your fork seals and change the fluid in your dampener.

 

[chrisarrington]

You really shouldn't go that fast.  It is very dangerous.

I would say tires. Unless you have really dogged it nothing should be worn out yet.
