Does any one know of any tyres out there for the 16" wheels, for track / classic racing on 851 tricolore or is this a case of changing over to 17's? If changing over does anyone have info on parts to do this?
Cheers

Avon do a set. AM22 & 23. I don't have any experience riding them. They are race only, I came across them while looking for tires for my RC30, but sadly, they aren't road legal in the U.S.

Golden Tyre from Italy do 130/60 ZR 16 and 160/60 ZR16 aftermarkets specifically as a replacement for the Pirelli and Michelin OEM rubber for 851, DB1 750S and the like. Check P42 of attached catalogue - downloaded catalogue from an Aus website
http://goldentyre.com.au/ or similar, there is also an NZ agent listed.

Mr.R
I've used "Track Formula" Avon AM22/23's on my seriously tuned 950cc 900SS Bevel, but they were obviously 18" and not 16" tyres.
They're very good classic race tyres but they don't last very long.
I saw off the lefthand side of the rear in an afternoon on the track on a very hot day at Misano, the track used to run the other way round back then.
IMHO if you want decent modern rubber on your bike you really need to convert it to 17" wheels.
We converted a mates 750 Laguna Seca to 17" using 600 or 750 monster wheels a couple of years ago but...
It wasn't a straight swap we needed to make up new centres with a different offset for the front discs, along with quite a bit more fathing around.
However we kept all the OEM parts so it could be converted back if need be in the future, as none of the mod's were permanent.

+1 for 17" wheels if you want easy to obtain, sticky, modern boots for your bike.

Hi Josh,
The feedback on the TT/F1 forum regarding the 16" Golden Tyres was good, but I believe they are only intended for street use. And I agree with everything Steve R. posted - it is a lot of work, unless you can come up with a set of wheels like the 17" Marvic three spokes that came on the '88 Tricolor Kit. Those wheels (and the new replicas) have the correct rotor mounting and offset for the older school (Pantah era) 280mm and 300mm rotors. The fork sliders on your '88 Tricolor Strada position your calipers for the older style wheels and 280 rotors, so if you switch to the newer 320mm rotor style wheels, you will also need caliper adapter blocks, or a set of the M1R fork sliders from a '89 or '90 851. An 851 on the race track needs 17" wheels - it's well worth the effort and expense.

Thank you all for suggestions, couple of options there and i have an 88 900ss which has 17's so might work through adapting those to fit the 851 and use for slicks and maybe use the 16s with road's / wet weather days...

I'll throw out a couple thoughts on your last post because I've been down this road before and I don't want to see you go down a dead end. Please correct me if I'm wrong. First - using your 16's for rains - those have 280mm rotors, so you would have to relocate your calipers every time you went from 17's with 320 rotors to 16's and back again (unless you came up with a set of the original style '88 Kit 3-spoke Marvic 17's also using 280 rotors). We have found that when rain is an issue, usually the bike is sitting there with no wheels on it until first call, so we can make up our minds about what tires to use at the last minute. Also relocating calipers at that point could be too time consuming, not to mention a PITA.
I was also puzzled about your "1988 900ss" statement so I checked my Falloon belt 2-valve book. According to Falloon, 900 Supersports were only '89 and '90. And while they used the white 1989 851 Brembo 17" wheels, the rotors used were an oddball 300mm size, although they do appear to have the same offset as the more standard 320mm rotors we're all familiar with. The '88 and '89 750 Sports all used 16" Paso type wheels and 280 non-floating rotors.
During the years around 1988 to 1990 Ducati's were evolving very rapidly and it is a little tricky mixing and matching parts from that era. Measuring your parts carefully so you know what you actually have is a good idea.

Thanks Bill,
Yes it i would say 89 900ss papers say 88, words of advise noted and for sure any swap on the day will want to be as smooth and quick as possible so will definitely try to have disc's spacings the same...
Will have eye open for the 3 spoke 17" but see what i can do with what i have at hand and or prey for settled weather!
Cheers Josh

the 300mm discs were also on the early 907.
