I have a friend here in New Zealand looking to replace his 320 mm Brembo rotors. These are the 320 mm brakes found on the Brutale 910 R model (probably others too but I'm not that well versed with the Brutale models). I do know they were also found on the F4 1000R / 312R & 312RR. See the picture below for clarification.

If you have a spare set of these available for sale (must be in very good condition) please send me a PM.

All the MV 320 rotors are the same through '09 model.....not sure the '10 +.....so basically any of the radial brake bikes should fit. I have some spare rotors, but not sure if 310 or 320. Will have to look. Not sure they are pristine enough for your friend either....they are used after all.

Not really, only the Brutale 910R has 4,0 mm min.th. rotors, all the other rotors (320mm) has the 4,5 mm min.th. Don't know why!

Laur.
Weight? The cooling requirements based on anticipated heating? F4 has higher top speed and slightly higher weight, so requires more cooling capability?
But the thickness will not prevent installation. All other dimensions are the same.

Very true! By the way, I have both thickness on my Brutale:smoking: and no problems (yet). That's how I bought it and found out after that.:wtf: As Donsy said about it: calipers don't know what they're squeezing.

Fill in the blanks:

Dave, or anyone else, if you could fill in the dimensions on the following picture, I can check to seek if the brand new set of Brembo rotors I have will fit.

Hi Chuck, I have been in contact with Jason (bogie1972) and we have come to an agreement on price so it would be very bad form of me to pull out of that deal at this stage so I'm not going to.

When you get a chance, please post up a picture of the Brembo discs that you have - I may be interested in them for myself.

Dave.

Chuck;
I was too lazy to calculate the 5 bolt circle diameter......I hate 5 bolt patterns, Offy cams are 5 bolt too

Ill be doing some measurements there myself today. I'd think that just measuring from center to center in a star pattern would be sufficient.

Chuck;
measure from the center hole to the inside edge of the bolt hole add 44.25mm and double it that's your B/C size

there's a formula going C/C but I don't remember it

It will be easier to simply unbox a rotor and line it up to the nice front wheel I have sitting in a box.....

Busy on the Night Shaft....I HATE NIGHTS!

I have just unboxed my rotors and wheels....it's a no go.
There is no appreciable offset (dimension F), and the center hole is too small to fit over the hub.

I simply tried to mount them on my nice used set of Ultra-Lights!

This is a full Brembo brake set from master to caliper, plus the discs, that was purchased to mount on a 1992 Kawasaki ZX-11. Iwas hoping it had the right demensions to help out. Turns out it doesn't.
