Though I don't really see the point; there was once a time when nobody saw the point of ABS and Traction Control on a super-bike. Who knows, this could be the next big thing. Right now Im happy with rear wheel drive, and standard braking; and I dont ride near fast enough to need or use traction control.

would make it difficult to do a rolling burnout... or any burnout for that matter.

steven32 · 08-15-2010, 11:11 PM

i wonder if it would feel any different to ride.

loopy · 08-15-2010, 11:29 PM

some things bother me about this one a leak in the drive system causing a traction issue . also if that front drive locked up at any speed your in for a ride of your life !!! cool idea though it would be somthing to ride for sure if the safty bugs could be worked out !!

Unlimited endo's. You could ride the front wheel for unlimited distance.

I wounder how much power will be lost by the bike having to drive that pump?

And as for the guy with the "Unlimited endos", you can have that.
The word Endo is a term for end over end. Flipping over the front of the bike once, would be too many times for me........

Endo - The art of stopping a motorcycle and having the rear wheel lift off the ground. Also called a stoppie

Might technically be the wrong terminology, but endo is often used interchangeably with stoppie.

As for the power loss...

Quote:

The quoted weight of 8kg additional weight was about right. Power up to 15% could be transferred to the front wheel, that was right too. But people were wrong about the power losses – it was only about 2.5bhp at 150km/h.

Another article on the subject.....

Power loss wouldn't be an issue, no one uses that much power as is.

The machines are far more advanced/have more potential than any rider this world can produce.

I don't like the idea of a hydraulic pump, it just seems like it would be unreliable. In a world where one minor hiccup can be disaster, it would make me uneasy. I would think you could burn it up pretty quick to considering how fast those engines are spinning. I could be completely wrong.

Ryan@IdahoSportBikes · 08-16-2010, 11:45 AM

It does make sense that traction would be better because you are spreading your power across a larger contact patch... but I don't know if that will actually mean you could lean over more or reach a faster top speed through a corner. Sure the average rider may be able to corner with increased stability/traction, but would motogp racers get better lap times? The only reason I pose that question is because it seems most things don't hit the market (on a large scale & by all major companies) unless the top racers in the world benefit from it.

HOWEVER... I did hear him say they do have whoses connected to the murder with more whoses connecting to the hump.
So I'd buy one....

I think wheelies would become very hard/impossible...

The motocross racers will know what I mean. Here's why I think it would be very difficult.

When you are jumping a dirt bike, if your front wheel is too low you give throttle & the rear wheel will start to come down. You actually level the bike out. Also you can do the same thing if your rear tire is too low and you want to bring the front down by hitting the rear brake in the air.

So I would think if you tried to wheelie a 2 wheel bike the front spinning would pull down harder and harder the more throttle you gave.

I would think stoppies would still be possible cause you wouldn't be giving it gas...

they show it doing wheelies in the video

Clearly I paid a lot of attention!

I think wheelies would be more sustainable. Once the wheel comes up I think it would be harder to go over the balance point. I don't know if that makes sense. What I mean is it won't just jump right up in to the balance point but rather allow the rider a little more time to reach the balance point meaning less chance of flipping over. Don't get me wrong I'm sure flipping it is still a possibility. The other advantage of having the front wheel rolling at the same speed as the rear while doing a wheelie means less chance of head wobble when coming down from a long wheelie that causes your front tire's rotation to decrease.

LckyTylr · 08-17-2010, 07:27 AM

I don't see how two wheel traction would be any better at any given time. If a bike wheelies, which this one obviously still does, then your front tire can spin for days and it won't make any difference. Same is true the other way, shouldn't help much under extreme braking as the rear wheel hops and dances. Has anyone thought about what it would be like to go into a corner really hot and dumping gears really fast to use engine compression to aid in braking......without a really good slipper clutch, even the hydraulic gear up front is going to give you some issues with jerky negative acceleration each time the clutch is released. downshift....stoppie......downshift.....stoppie... ...downshift......stoppie..... just a thought. I think it is really neat, very impressive engineering, but I think it's almost useless for a sportbike. it might have an application for touring bikes, cruisers, commuters, as those are rarely ever ridden on one wheel or barely on two wheels. dirtbikes, well yup, it's very useful for dirtbiking.
