Imagine taking one of these in to your local shop to get a new tyre fitted.....could ask them to re-spoke it I suppose....tell them "they all fell out" :rofl:

They could make that look really good. Shame they made them look all concept like

Bloody good idea, those wheels.
The most efficient flywheels have fuck-all mass in the centre and heaps of mass around the rims.
Those wheels are the ultimate flywheels - absolutely zero mass in the centre - they're nothing but rim.
The gyroscopic effect of those wheels would surpass that of any standard wheel. A motorbike is essentially 2 flywheels/gyroscopes held together by a frame and we use that fact to steer it, keep it upright etc.
I saw something like those wheels on "Beyond 2000" may years ago on an experimental bike but this is the first time I've seen a production machine using them.
Dunno if I'd go for the designs they have, but I'd certainly be up for hubless wheels on a bike.

Wouldn't be that good for handling as it would want to keep the bike upright instead of going to the side and turning. Would make a very stable cruiser though
Wonder why they stopped that "Beyond 2000" show...

Countersteering, unless I'm way off, works because you're turning a gyroscope (front wheel) which causes it to tilt and thus the bike tilts - despite the gyroscopic "stabilisation" afforded by the rear wheel. Surely with an improved gyro on the front, your countersteering would be more efficient.
Physics students feel free to correct me - I wimped out and took chemistry (so correct me politely or get used to checking your ignition systems every day... :devil2: )
On "Beyond 2000" the test rider reckoned it handled beautifully.

As far as I know, the lighter the rims, the easier it is to flick the bike from side to side because you don't have the gyroscopic resistance. Thats why carbon fibre/magnesium rims are so cool

So if you dropped a bearing at 200 clicks the rim would fall off?
No thanks :no:

Wondered when people would start putting those on sport bikes.

they would look awesome on any bike really.
Can anyone photoshop one for us? (i would but i am no good at using photoshop, and don't have it anyway)

Hmmmm. Thanks for the links. Dymag seem to be making the complete opposite to an "ideal gyroscope" - weightier hub, light rim. I would presume they are doing it for a reason, that it is what the performance riders are demanding.
Blows my theory, big time.
Also very polite, alarumba - you can start your vehicles without fear...

I thought the lighter the UN SUSPENDED weight, the eaiser it is to flick around?

I'm just going by what I've read and been told
I'll save up for a set maybe. Could get a F3 bike for the same money though

Bit pricey. Would be interesting to see how it effects your bikes handling and performance
Awfully tempted to save up for a set. Not sure if streetstock rules would allow them

These ones are for the GP125s so should fit my CBR. A front rim weighs 2.2kg!
