speed wobbles - Page 5

 

The TOGster bloke broke radio silence to address the English-speaking
motorcycle community thusly:

 >> *Every* motorcycle has a critical speed at which it begins to weave.
 >> Big sportbikes just do it at over 120 mph.

I am constantly astonished at what I discover on Usenet.

 > This is total, utter, complete, pure, hallmarked, certified, attested,
 > 24-carat, 99.99% fine nonsense.

So you're acknowledging that it's 0.01% true?

*Some* big sportsbikes might do it. Got to leave a small percentile to
chance ;-)

Bullshit. You can take a brand new sportbike with brand new tires and
have the chassis aligned with laser beams and the bike will still
speed wobble or speed weave (according to which tire has less than the
required traction) when you
cross rough pavement (causes wobbles) or ride on slick surfaces
(causes weaves).

I helped a friend who owned a GS1100 to take it to Buchanan's in Los
Angeles to have the rear wheel aligned with the steering head and the
steering head angle checked.

Buchanan's couldn't find anything wrong with the alignment, so he put
the motorcycle back together and sold it, because didn't like a
motorcycle that
speed weaved around 120 mph.

It was a case of "they all do that, sir."

The rest of us put wider rims and wider tires on our GS1100's and I
even pulled the front forks up through the triple trees to get the
stability I wanted on the race track at the expense of easy steering
in parking lots.

My friend didn't want to go through all that, so he bought a BMW R75
which did all kinds of weird shit due to drive shaft jacking and
torque reaction.

But he thought that his "Rubber Cow" was wonderful because it was a
BMW...

 



No, it won't.

You haven't ridden a modern bike, so your reference points are all the
antique bikes you owned....
 

... like this.


And it had a flexy frame, nasty tyres and spindly suspension :-))
