thanks Im checking few options also.I agree that the front end has big effect.Have consider the front stabilizer shck also.We had them on the funny cars to keep front from bicycling.If you think these are bad a funnycar will literaly break your hands if it starts while backingup and you try to hold wheel.Im looking at bushings,rear stabilizers,front stabilizer and if all fell Ill just cu the damn thing and add 4 degrees to front end.I think the 28 degree rake is big problem too.

 

High speed wobble- Dont' mistack fork flex (cornering) with a wobble. I did some road racing for kirker (20 yrs. ago) and we used fork braces for fork flexing in the corners. We also used stering dampners for high speed wobble. I have the same problem with my Rocker at 90 mph and above and have not fixed the problem yet. A tappered head bearing also helps because with a tapered bearing you can tighten the steering head up a bit more than useing one that is not tappered. When I was raceing we found that mix matching front and rear tire manufactures also helped with certain tire manufactures. As I have always under stood - speed wobble is created when the rear section of the bike (everything behind the goose neck) is actually starting to go faster than the front. So this would mean that there is more rolling resistance on your front tire. I think that is why changing tire tread patterns from front to rear always help. But of course - I didn't have to pay for all the tire swapping to experiment and find out what tires created the correction.

 

okay...you're doing 120mph on a touring bike why?

Because you can? Perhaps my accident has tainted my thinking, but if you are wanting to ride at 120...buy a crotch rocket.

As for high-speed wobble/frame flex, I had that induce on my '07 Ultra in hard-sweeping turns at around 70 mph. Had I still the '07, I'd probably put one of the Touring Stabilizers on...but, 04/25/2008 squelched that situation.

 

If you need to go 120 mph then I hope you're on a track. There are lots of people on the roads and we don't need another problem. Just saying.
