Re: PVM Wheels
For the weight difference you might as well get the "Y" spoke.
This is from 1000RR.net:
So I finally started wrenching my 1000RR in preparation for upcoming track season. Since I was taking the bike apart I though I'd put some parts into scale as there has been a lot of discussion on where one can save weight and how much this and that weights.
So here we go
Front wheel: 4000 g (without disks, bearings installed)
Rear wheel: 5500 g (without disk, bearings installed)
Chain: 2400 g
Swingarm: 7280 grams
Shock: 2780 grams (in comparison my WP shock weight 2920 grams, but that is with remote preload adjuster)
OEM rear sprocket (530/40): 540 g, my 520/42 alu Renthal is 240 g
OEM Battery: 2900 g
OEM rear brake disk: 800 grams
OEM exhaust: header 4750 grams, muffler+valve 4800 grams, heat shield 500 grams
OEM Clipons: 330 grams each
The OEM wheels seems to be quite light, when compared with for example PVM forged alu aftermarket stuff: PVMs are 3500 and 5000 grams, so only a total of 1000 grams gets saved. Forged mags are a different story, PVM's are around 2000 g front and 3000 g rear. As a side note RC51 front is 4770 grams.
Unfortunatley, I don't know the conversions.
