    Agreed. In fact viewed holistically the motogp vs superbikes is a wankstain!....remove Rossi from motogp and folk would turn away in droves.

    Much better to have a true prototype class with bugger all rules [i.e 800's, 500's and 250's all 4 strokes] and keep the present superbikes.

    WKBS,

    Pnuematic valves haven't made it to production yet because the existing systems leak. The race bikes have a back up reservoir, if the pressure in there drops below a set level, the engine cuts out. That's a much cheaper option than it keeping running (momentarily) with valves stuck open. All very inconvenient on a road bike.

    Carbon discs work at very high temperatures. They don't work in the rain.
    Moto GP bikes change to steel discs in the wet. Most street bikes will occasionally encounter rain, so as it stands, carbon is not an option for street bikes.

    Maybe one day...

    Dude, I already knew all that. Thats mainly my point that motogp stuff never seems to trickle down because it's all designed conceptually to last one race with max power. He said if the idea's a dud it dissapears, where as the good ones are passed down to proddy bikes. MotoGP specific idea's for instance like carbon disks, high output v4's, pneumatic valve control, and other stuff like that are only ever going to stay with MotoGP bikes because it's either too expensive to produce (v4's) or as you said it just isn't viable to have to rebuild a bike part between rides (pneumatic vc/carbon disks if you can use them usefully).

    Sure, the cross-plane crank off the M1 is worth it, it fits into the current engine with no huge change in production cost compared with making a v4 with twice the valve train which is going to make it a lot more expensive to produce isn't it? That's about the only major trickle down effect I can think of besides just general improvements in design which isn't really due to MotoGP is it?

    Fuck all people can fully utilise the capabilities of current sportbikes, whats the point?-See below:

    So are 200hp+ road legal sports bikes... That said, I'd buy one if I had the money!

    So would I, but I'd also spend the purchase price of the bike in the first six months running it. Did you consider that side of it?
    That's what I mean about being able fully utilise it, it's not just about being able to ride the bike, you have to be able to maintain it.
    It's hard enough with 100hp let alone 200, trust me I know.

    Are you talking about an R1 for instance? I would have thought they'd be cheap to run... I'll take your word for it tho

    I think they are a brilliant set of rules , as a Engineer all the obvious avenues a nailed shut ,,, but the there is more than one way to make a bike go fast,,,,

    Remember it wasn't just Rossi ...who won the championship ..it was Rossi and burgess and co ,,, , How many Gps did Honda win after burgess left???

    Sod the motogp ..this class will be interesting ,,,,

    lets think of a few things that have trickled down;

    Aluminium frames , Suspension , radial tyres , The 2 stroke expansion chamber, ( the Oval piston !!) .... short rod ratios , pressure casing ..................you can add to this if you want ,,,,

    Racing is a business , and helps shift bikes off the show room floor , .....it trickles down all right


    I race , a vintage bike its used as a rolling test bed .....

    Come on man! Just think of the things that have filtered down from motor racing: The wheel, the internal combustion engine, petrol, the ball bearing, aluminium...

    Just to counter my slightly negative earlier posts, I believe the biggest thing that has already started to filter down from the modern 4-stroke GP racing is electronics.
    It's obvious that even the Rossi's, Stoner's and Gibernau's of this world can't use all the power of that the bikes have for at least for the full duration of the a GP, tyre technology just doesn't allow it yet.

    Switchable ignition curves aren't exactly new, but corner recognition software in the engine managment system is an example of what's achievable, how that could be applied to roadbikes is a matter for conjecture.

    The change to 21 litre fuel tanks has also had a dramatic effect on how long the bikes can run at their full potential. Ducati together Shell have been the leaders in this field, I was positive Casey's bike was going to run out of fuel at the 07 Qatar GP but the bike ran hard right to the end of the race, though I don't think there would have been left for slow down lap shennanigans.

    So oils and fuel technology could be some of the things that filter down relatively quickly, a bit boring compared to pneumatic valves and carbon bling widgets but it all goes towards making machines work better and perform better and that can only be good.

    Back on topic, I just can't see how the the rules as posted for Moto2 are going to further any of this development.
