Apologies in advance if this has been discussed in depth somewhere else, if so just point me towards it. Also, since I'm not sure if this should be in Tech or A&M, mods please move if you find appropriate.
What I know so far: 6 bolt disks have a 10mm offset while 5 bolt disks have a 15mm offset.
What I don't know is: do triples and calipers matter?
Case in point, I have a 996 frame and sbk forks (65mm offset) and now I'm looking at front wheel options. I've found a few 999/749 complete (rim + disks + bearings) front wheels on ebay in good condition, these wheels have 5 bolts and 15mm offset.
My question is: if I get a 999/749 top triple, will everything else bolt on? Or do I need specific brake calipers as well?
Thanks in advance to anyone who can help me.
I'm not 100% sure but I think the rotor offset is in the fork lowers. So to install the 999 wheel you would need 999 forks, or at least the lowers off a set of 999 forks. Or find a source for 5 bolt rotors in the correct offset.
Thanks for the answer, although I was hoping for a different one ;) Unless I can find some 999 forks on the cheap, I'll pass on that.
I guess the obvious question now is: 'where do I find 5 bolt rotors with 10 mm offset?"
i believe the offset is in the discs and forks, if u look at this page http://www.gothamcycles.com/servlet/the-Brakes/Categories (http://www.gothamcycles.com/servlet/the-Brakes/Categories) they list the different disks for the various bikes and their disc offsets. i believe the wheels are the same width across the range so you'll just need to find a wheel and disc combo to suit the 10mm rotor offset your 996 forks need or modify to make it fit.
Where i know the wheels vary is in axle diameter and bolt pattern. So you'll need another wheel with the correct axle size or to change the bearings to make it the correct axle size. You'll also need a wheel with the correct 10mm offset rotors that the 996 forks cater for or find an adapter to space your callipers back 5mm or if u get a 6bolt wheel you could use your existing 996 6bolt 10mm offset rotors or find some 5 bolt rotors with a 10mm offset to put on a 5 bolt wheel. i also believe all the 65mm callipers have the same offset which allows all this to happen.
CAN ANYONE CONFIRM THIS!?!? this is only my researched understanding.
Thinking about it i have a 748 wheel here for my bike, it would be a direct fit for your 996 as would a 916 wheel. they are all 6 bolt 25mm axle wheels with 10mm offset discs.
999 wheels are 5 bolt 15mm offset std and 25mm axle
so if all i said in above post is correct then you could use a 999 wheel as long as u space your callipers out 5mm or find some 5 bolt 10mm offset discs to suit. quick look came up with hypermotards having a 5 bolt wheel with a 10mm offset disc but im unsure if they will work. maybe you could use a hypermotard disc on a 999 wheel. more research needed but thats as much info as i found when researching wheels for my bike.
good luck, Cheers Clint
this is all correct.
the 999 fork lowers would place your calipers 5mm further from the location of your stock disks, just adequate enough to fit the proper 999 wheel and rotors in there.
i have 999 forks on my s2r 800, and to accomodate my stock wheel and brakes, i had to use 5mm spacers (and longer bolts) on my calipers.
the offsets here are independent of triple clamp dimensions.
technically speaking, to fit that wheel to your forks, you would need a -5mm spacer for your calipers (which is impossible), or you need to change the offset of the rotors to 10mm (which i dont know how to do).
general rule of thumb i think is that if it's 999 or 749, it's not going to fit anything else... without some help.
any other sbk stuff usually works okay.
so next is the question of hypermotarrd disc on 999 wheel, or just hypermotard wheel and disc. anyone tried that?
suppose it kinda seems a little pointless, unless the price i really good on the 999 wheels you would just go with 748/916/996 wheel.

actually i have seen this, on this forum aleast once im sure. they use a adapter block that moves the calliper further down around the rotor and steps out from the original mounts.

I've read about another solution which is to shave off a few millimeters off the calipers, the caliper mounts on the forks and the disk mounts on the wheel to compensate for the 5 mm.
Come to think of it, -2mm at the calipers + -1 at the fork mounts + -2 at the wheel and it's all set. Of course with any such project it's much easier said than done. Especially ACCURATELY done :-\
As for 748/9*6 wheels, I've found plenty of them but they're all 3 spoke "heavy" aluminum cast. I'm looking for something a bit lighter without breaking the bank. Thanks tho. [thumbsup]

I THINK the hyper uses a 305mm rotor, which tosses that idea out.
999 forks - easy to use 999 wheels/rotor/caliper setup.
You have 2 options as I see it:
1st option you have is IF the rotor mounting area has enough room, you could have the wheel machined down 5mm on either side.
2nd option. Use a galfer GSXR rotor. 0mm offset, and a 5mm spacer. Same bolt diameter as I can see, 320mm rotor. That would work, and probably be easier, although you'ld have to buy the rotors and spacers. Would be cheaper to just buy a 999 front wheel :)
The hyper is the only duc with a 5 bolt 10mm offset weird diameter rotor. WHY ducati!

do u mean 996? ;D
Not if he wants to run 999 calipers on 999 forks without the above fixes... 996 needs the 10mm offset rotors, and 5 bolt 10mm offset rotors don't exist.
If you've got the 996 wheel, get a set of the GSXR 320mm rotors, and a 5mm spacer= now you've got a 10mm offset.
- or machine the wheel down, ONLY IF there is enough meat there to still get a good bite on the disc bolts.
i didn't read everybody's replies, but just wanted to say:
the triple clamp doesn't effect the wheel choice. the fork lowers dictate which axle, wheel, caliper, and rotor one must use.
that's the simple rule.

Thanks for the link, that seems like a pretty sweet deal! And thanks to everyone for the replies.
'a m' your post pretty much sums it up.
I've decided that if I can get a complete 748/9*6 5-spoke wheel for the right price I'll go for it, if not I'll get a 749/999 wheel and forks. It'll just come down to $$.
Just mind your brake requirements: if you have 40mm mount calipers and get late 9*6 or **9 forks with 65mm mounts, you'll need adapters (and vice versa if you have 65s and get 40 lowers). Also the **9 lowers have funky fender mounts.
