Not only that, but look at the price! Clearly out of his mind.

 

^^^^^

Begin, obviously. I think those spinning wheels do something odd to the
mind....

 

Wouldn't that **** up the handling completely as well , having what looks to
be a substantial weight rotating at a different speed to the wheels?

I saw wheels like that on a Merc CLK the other day - they look
unbelievably gash.

 

Merkins. Take a perfectly good Jap or European sprot bike and make it look
like a proverbial tarts handbag. Arse up the handling to the level of the
Merkin home product. Ugh.

Could someone please provide a rationale behind that product, and could the
OP redeem themselves by explaining WTF they were searching for?

 

No.

To set your mind at rest, I saw the link in
alt.binaries.pictures.motorcycles.sportbike from a guy who said:

"Check this out"

obviously a little excited by the whole thing. I just couldn't believe that
anyone could do something that sad.

Good argument.

Sadly enough, I had a look at their website, wanting a bigger picture
as I'm struggling a bit in understanding wtf these wheels are. Same
tiny pic, no explanation. Oddly, _no_ customer reviews, either.

I assume that these are the same thing that's been about for a while -
that the wheels are fitted with a bearing-supported chunk of metal
that continues to spin when the wheel is stationary?

I'd like one of the resident fizzicysts to advise on the implications
for handling; not to mention the rather silly addition to unsprung
weight for cosmetic porpoises. I really can't see the point.

 

Its got me convinced

Yes.

 

I forgot to include the long version.

Firstly, gyroscopic effects are orders of magnitude too small
to affect the handling of a bike. If you think that gyroscopic
effects are the reason that countersteering works, i.e. that a small
push on the bars gats a bike well banked over, just think what effect
getting both wheels (and the whole bike) rapidly over at 45 degrees
would have due to those same gyroscopic effects.

Secondly, the free spinning disc is lighter and closer to the
spindle so has a much smaller moment of inertia than the rest of the
wheel, so any gyro effect will be an order of magnitude smaller again.

Roger.

 

OK, you're redeemed. I really would -not- like to ride a bike equipped with
those things with anything approaching enthusiasm. I don't know the physics
behind it, but I will hazard a guess that they do some very odd things to
the front end.

If they in any way assisted the handling of a bike, you can bet the Japs
would fit them as stock within the constraints of production engineering.
Quite a good arbiter that, IMO.

What next?, valve caps that light up?, leading link springer forks?.

Might help if you wanted to countersteer a shaftie.

 

Why would a shaftie be different from a non-shaftie ?

 

<applause>

There was a guy back in the last century who built a bike with heavy
steel rings running on rollers inside the tyres. He wrote it up for
Motorcycle Sport in about 86 or so. When he had built the thing, he
went for a ride to get the rings spinning, then come to a
halt...waited...fell over.

Cyclists - the lycra mob, on those spindly things with no engine - their
wheels weigh 3/16ths of **** all. They use countersteering.
Countersteering is powered by the magic of geometry, where you steer one
way, and your track goes out from under your CofG, and you fall the
other way.

Funnily enough, I ask myself "Does Rossi use an RF900?" and when the
answer is negative, I know that's why I'm not as quick as he would be.
See?

It makes sense in my world and I'd thank you not to disillusion me ;-)
