    Sidewinder's renowned for blowing competitors in the pits, doesn't need lightened wheels for that. Choppa seems to do alright ontrack thus far without lightened wheels too

    yea just put more air in them and they will be lighter

Mind you it is only physics and not me just carping on about my really great product!!!
    Hey Loco, no-one for one minute doubts that such wheels are great. I think Choppa has eluded to it further along about lightweight tyres. He was obliquely referring to Dunlops that have a heavy carcass. Thats a disadvantage but arguably the Dunlops have strengths in other areas that more than make up for the weight and inertia penalty.
    I agree with you about the distribution of mass.

    Thats an interesting comment about light flywheels and I guess you are referring to 4 stroke motors. In a 2 stroke its not quite the same. If you lighten the flywheel the motor will spin up faster ( and pop wheelies too readily ) but will lose a lot of over-rev after peak torque. That because there is less inertia to let the motor rev on as the expansion chamber tuned length is past its peak.

    How about we fill the tyres with helium?

    You should be using nitrogen!

    Fair enough. I wonder if the GP and World Supers teams use it?

    You should be able to get around 98-99% nitrogen in it without any special gear, we've tested at work and that's what we end up with

    Well if thats the case it still changes pressure the same as air

    Nope, nitrogen remains more constant through a wider range of temperature. That's why it is used, and you should have some bottles in your line of work.
