Halfdoesyn Posted August 5, 2016 Share Yes http://i.imgur.com/5EGjdIT.pngMight be, but a single disc on a wheel does not cause it to pull to one side. The purpose of 2 brake discs might be:to increase the braking powerto introduce redundancy - provided you have separate circuitsfor blingIf a single disc would cause such an effect, I'm sure we would have noticed SOME evidence on single disc implementations.

Buells are notoriously bad when trail braking into corners, and the feel is different trailling to the left and trailling to the right. And as all motorcycle racers know, feel is extremely important. That's also why the lightweight GP bikes run two tiny disks, as opposed to one large disk. Sure, overall weight might be higher, but the mass is located closer to the centre of the rotation, improving resistance to rotation and providing much better feel and modulation. http://i.imgur.com/NYrQnJP.jpg Link to comment Share on other sites More sharing options...
NotSoBigBen Posted August 5, 2016 Share I have have a 180/160 combination on my bike. I weigh 94kg. Should I fit a 203/180 ? Ps. I only ride the spruit. For the Spruit I would take no less than a 203mm Carbon Fiber rotor with 4 pot calipers Link to comment Share on other sites More sharing options...
dave303e Posted August 5, 2016 Share Even cars have this bias, look at bakkies especially, a lot have disks up front and drum brakes rear, or bigger disks up front... Link to comment Share on other sites More sharing options...

Captain Fastbastard Mayhem Posted August 5, 2016 Share Damn! Almost worked. My only point is that a single disc does not cause a bike to pull to one side.Exactly. On moto3 bikes, it's solely to do with brake fade and avoiding it as much as possible when you're constantly braking from very high speeds. Road bikes don't *need* it as much unless they're doing track days and go over the speed limit all the time, but it looks cool. Link to comment Share on other sites More sharing options...
