Aftermarket wheels for new National SUPERBIKE rules

[White trash]

Hey you could blow off a few more competitors

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

[Sidewinder]

We run the heavy ones actually

i know thats why we get you to race with the 2nd hand ones because they have less rubber. my thought on light rims is like having a light or no fly wheel heaps of top end but no tourque

Yow There Sidewinder - Imagine though just for second what would happen if you ran Lightened Wheels and Tyres given of course that Wheels have a broader Plan of Mass than a tyre does across the Diameter of the Wheel. Carrozzeria Wheels Have a Whole Lot More of their Mass small though it is - at the centre of the wheel, so Hey you could blow off a few more competitors using both these items and a finely tuned suspension set up - Now would'nt that just be a winning formula for race efforts. 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.

[CHOPPA]

How about we fill the tyres with helium?

just dont forget to bring your jug

done deal!!!!!!

You should be using nitrogen!

[CHOPPA]

You should be using nitrogen!

Tried it but it doesnt work unless you vac the tyres and thats too much hassle

[Crasherfromwayback]

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

and your to fat for lightweight wheels to make a difference!! eat some celery tubby...you'll go faster!!

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.
