Quick question...what's the biggest rear tire can go on a 696? It has a 160 now and I'd like to beef it up to 180 or 190.

If i swap out the swing arm with a 796 or 1100 single side, will that accommodate bigger tire? or do i need to make adjustment at the front sprocket as well?

Thanks!

if you like the handling of the bike now, leave as is, you have a 4.5" rear, to even fit a 170 you would need a 5.0" at least . . . wider tire would also "slow" your bike's turning ability . . .it will also feel 'heavier' . . . you might have issues with clearances between chain and tire and it might be difficult to get a 5.5" rear for the bike unless you go aftermarket . . .

the 696 still not as nimble as the 620/695 but . . . I might be biased towards the old full trellis frame bikes . . . the turn in with the OEM Pirelli tires was good, with the second set, Dunlop D220 it was even better and now with my Michelin Power Pilot is even better . . .

What he said.  The wider tire will slow down handling and weigh more.  If you go wider on the rim, you will very likely have to shim the front sprocket out.

What's driving the desire to go bigger?  My M750 with its 160 rear handles quite well.

Ducati sold a wheel set (5 spokes, 5.5" rear) and it didn't require any mods, no change in sprockets or anything (says the internet). Other manufacturers might position their rear sprocket differently, but then should be able to tell you if they've done that and if it requires mods to the front sprocket.

The point is that it seems to be room there for a wider rim and tire (again, if the internet can be trusted)

It's more about the wheel size (width) than the swing arm. But of course if you swap to a single sided swing arm, you need a different wheel.

And not a 160s are created equal, some like the Q2 or Q3 are about 169 wide at their widest point, though they are a 160 size. On my sumo, pirelli Rossos fully cleared the chain, the dunlops *just* make contact when the tires deformed from load and track flogging.

Dunlops are always wider. I recall something about them being the DOT limit for width on wide-ness. And who cares if it hits the chain... they'll work it out quick enough. ;D

Thanks for all the inputs. This bike will be a custom build and I'm planning on building a new trellis swingarm. If the stock swingarm can accommodate a bigger tire then i'll build the jig to the same specs of the stock swingarm. Because if it does not then I will adjust the swingarm width when making the jig. I'm not looking for something too crazy, 170 will do and 180 will be very nice.

can someone post me a link to one of these wider wheel sellers?

thx!

Hi Daz, just buy used Ducati 5.5" rear wheel and put on a 180. Or research other bikes' for one with 6.0" wide wheel and put on a 190. If you're building the swingarm, all you need to do is line up the sprocket with the front one. Bug Norm.

Great info, thanks. I remember a while ago someone was talking about building the trellis swing arm. Has that been realized? I'd rather buy it from some shop then start from scratch.
