Title: rotors - 320mm, 6 bolt, no offset - what bike?
Post by: junior varsity on January 16, 2011, 05:55:29 PM
i ended up with an extra set of rotors that are 6-bolt, 320mm but have zero offset.

Any idea what bike would take these?  I'm guessing non-ducati.

Aprilia used the same setup as does MV.  I had a set of Aprilia narrow bands with a VERY slight offset, but I sold them.

These are perfectly flat... so does that eliminate Aprilia/MV? I thought Aprilia used the 6-bolt 10mm offset 320's that are on all the older ducs...

for most of their bikes.  They used a narrow band rotor with the same offset as the SBKs but with a 6 bolt pattern. 

i've not seen any genuinely FLAT rotors except on older bikes and usually iron rotors.  you mic'ed them right?

Huh...  Odd. Looks like the Ducati 6-bolt pattern (64/80), and the carriers look like Discacciati's other stuff...

Dunno, maybe one-off's?!?

I ended up with them without being able to put my hands on them really (not quite sight unseen, I saw the 6 bolt pattern but was in the dark as to the offset.) luckily I'm out almost no dinero.

nope berringer 6 pots. fwiw harley has a upgrade brembo rotor package for the streed rod (or whatever its called)  i remember that the rotors and calipers were all silver like that, cant remember if it had 1 or 2 up front though. [bacon]

uses those two-piece calipers...

theo might be able to shed some light.

all 999 = 5 bolt rotors, these are 6.

6, and these are WIDE band if there ever was - lots of surface area for the pads.


they become sweet looking really heavy clocks if I can't figure it out.

If they are around 5mm thick and have an 132mm center and the bolts are in a 150mm diameter pattern then they are for a Yamaha YZF.

I only know this because nobody makes aftermarket rotors that fit an 02 Duke II, so I was looking into getting a 5mm mounting plate fabbed then using one of these rotors bolted onto the plate.

You can make spacers to give them the offset they need to work on a Ducati. 5mm thick section of round with 6 holes in it and a real big hole in the middle. I think Jeff at Brake Tech has those for sale. www.braketech.com (//http://)
