looky looky what i found...
"According to Carrozzerria......the '07 V6 front wheels are supposed to weigh 7.8 lbs and the rear is supposed to weigh 11.6 lbs which would make them lighter than Marchesini forged alum 10 spokes.. OEM stock 'Busa 3 spokes weigh: front 11.5lbs rear 17.0 lbs. The '06 V6s weigh: front 8.9 lbs rear= 13.1 lbs. "
soooo... if stock gsxr1k wheel wheighs about 6 pounds less than a stock busa wheel... and a stock busa wheel weighs 17 pounds, then a stock gsxr1k wheel weighs about 11-12 pounds.
unless he meant wheel assembly as in just the front and rear wheel maybe with rotors? what do rotors way 2 pounds or so?
17+11.5=28.5+10pounds(rotors,sprocket, cush) = 38.5?? then in that case each gsxr1k wheel would be about 3 pounds lighter than the busa wheel... too much thinking, my head hurts. so a 1k rear wheel by itself would be about 14 pounds then...
and the Carrozzerria's would be about 3 pounds lighter than the 1k wheels in that case.
