Thanks, Mark, I`ve been meaning to add -

Rick Oliver upper radiator - 900g

(well it`s lighter than HRC...!)

i know the rear 3 spoke dymag is approx 1kilo lighter than standard 17''

Updated with this new info!
Thanks guys.
Kay

Here´s a little contribution, rally.

Rear shock springs (to compare relative weigh, spring rate and leght should be taken into account)
showa nc35 1108 gr (Free length 188mm, 140Nw mm??)
öhlins 1106gr (Free length 147mm, 150Nwmm)
Wilbers 1010gr (Free length 150mm, 120Nwmm)
RCS 650gr (Free length 147mm, 120Nwmm) Titanium coil, öhlins fit
Titanium will be around 40% lighter than steel, same as with nuts and bolts.

I am currently running the RCS on a öhlins,15mm preload, but would be better off with a 130Nwmm, even though I´m a light jockey (60kg)
Cheers

The Tyga Twin Stack alu muflers are 900g each

Updated with the two above and my new puchase.
A 370 gr durbahn 2,3A battery!
And it has a CCA of 300A so it will be more than enough for a carbed bike.

Keep them coming!

Hi

late type NC30 forks, only the fork legs (no yokes, spindel, mudguard or brakecalipers), but ready to go (meaning springs and oil) 7.1 kilo

When you have done all you can to lighten the bike, then get your weight down as much as possible.

Finally, Casio do a titanium watch and Specsavers do titanium framed spectacles for those that wear them.

arsey.
Since last winter i am down 20 pounds, the Specsaver titanium i allready got, but the watch is a good tip.
Thanks! :D

err or u could just take the watch off.....

for the true weight contious the way forward is riding stark bollock naked with knee sliders duck taped on, o and mabe a neck tube...wouldnt want to be getting cold would you :D
