not TT1/F1 but who else would have these....

thought i had 1989 900ss forks on the 750 Sport project but the 320mm rotors dont let the calipers bolt up.

pretty sure it will be the 907ie BB1 forks that take the 300mm rotors then. annoying.

anyone have some rotors hanging around?

or a whole wheel......

Sean

Looks to me that you have 89/90 900ss forks there but they actually did come out with 300mm disks as did the 91 907.In 92 the 907 went to 320mm disks.sorry cant help you with disks but i think the 300mm disks will be what you want

Hey crowster,

so these specs are slightly wrong then?

yep i would say they are wrong.I bought a 89/90 model ss from new and mine had 300mm disks and the same forks as you have on your bike.In my falloon 2 valve book he also confirms this

One or two months ago this fellow, Nick, had what you need. If they are gone then you can look for Yamaha TZ discs (Yoyodyne); same in every needed measurement. MikeV

And, there are these: http://www.ebay.com/itm/Late-Ducati-300 ... 1e&vxp=mtr

Do those Supersport 300 rotors have the same pilot dia. and mounting hole pattern as the 320 rotors?

And Mike, are you sure there isn't a small offset difference between TZ and Ducati rotors?

Bill. I'm not sure of anything. But the bolt holes on the new ones on eBay (they look like take-offs to me) are 80mm, and the seller would certainly help with info. I have a set of Brembo 300mm TZ rotors, and they are "flat", like all the Ducati versions of the 1990s-2000s, often shown as 10mm offset. The centerline of the discs on later-version wheels is 120mm, same as on many Ducatis of the 90s and after. If they are that close something can be made to work. Someone one eBay is selling 2-6mm spacers for the 64/80mm pattern now. MikeV

Thanks for all the help and info
