Yeah, brake discs are different part numbers between RR and R. And as far as I know, the RR wheels are not lighter than R wheels. So it's purely an aesthetic thing. They do look great though.
I wonder if there's a weight difference between the RR Marchesinis and the aftermarket ones. The RR wheels have smooth spokes while aftermarkets have some definition in them. The aftermarkets are most certainly lighter than OEM R wheels--but how much depends on the alloy. Magnesium are probably lighter than Forged aluminium. The RR wheels are Forged Aluminium but are they the same? I have asked a few people and I keep getting different answers. Some say RR wheels are a few pounds heavier and other say they're on part with R wheels. I wish there was something more official on this. The only thing that's confirmed is the better weight distribution of the RR wheels and they look dank as fuck.The Ninja ZX-10RR runs forged aluminum seven-spoke Marchesini wheels, with Pirelli Diablo Supercorsa SP rubber.
Are the Marchesini wheels built so the weight of the wheel are toward the center of the wheel for less gyro?Are they suposed to be 25% lighter and stiffer than stocker anyways? I am confused? You talked to the wrong folks!
Conformed. This is correct. The RR OEM hub is different than the standard Marchesini wheel hub.So the Kawasaki parts catalogue says the ZX-10RR rear hub and sprocket are the same as the standard R version. Can anyone confirm this because I'm trying to buy a set of Marchesni wheels for my R but don't want to buy a whole new gear set. Thanks.
