What about Helium:lol::roll:

i remember from school that compressed helium weighs more than compressed air anyway....

Is it not something to do with Helium being less heat sensitive !

why do balloons filled with helium rise then?

The air in a tyre will weigh about seven times more than helium in the same tyre at the same pressure and temperature.

It look like you have access to some data and I was wondering if yoy knew how much the 3 spoke Brembos weighed in at.

When you list the weight of the OEM 5 spokes I assume these are the as delivered items (as opposed to the forged items) that first appeared on the 2000 SPS and now grace everything including Monsters and STs?

Thanks,

Marchesini magnesium 5-spoke ... 6.8 lbs ... 8.7 lbs. rear
Ducati OEM aluminum 5-spoke ... 9.3 lbs ... 12.0 lbs. rear
Ducati OEM aluminum 3-spoke ... 11.5 lbs ... 13.3 lbs. rear

Ducati lightened the wheels in 1999 compared to prior years. I don't know how much, but they said so in their '99 brochures. Could be just a few grams.

Wow, so if I had the dosh, changing the Ally 3 spokes (with Dunlops) on my 888 for the new Marchesini Mag 10 spokes (with Bridgestones) would be like halving the current wheel mass. Wow.

Thanks.

Y shaped 5 spoke
 

Hi

When you talk about the Marchesini 5 spoke are you referring to the new Y shaped in light alloy that come on the 999/749s?

If not does any one know the weight of these to work out if its worth changing for magnesiums?

Thanks
Peter

TOTTO NO

Your thinking of Nitrogen mate.
