Will it fit and will it work good are two different things...plus it will look like crap, but that's an opinion.

ive got a stock 900ss wheel 4.5 wide would a 180/55 tire fit on it?
ducati list a 180 alternitive on the bike and in the manual for my 800ss. 170 alternitve for the 1000ss.

the 170 handling better????? thats a matter of preference. the 170 has a steeper profile then the 180. and a 160 generally has a steeper profile then a 170 and so on. the steeper profile will make it fall into corners easier. maybe to easy for some? means less muscle to turn at very fast speeds.

as for as the FAT tire look, yeah thats gay. but a 180/55/17 is a good all around size and very common. i wouldnt go bigger then that on any bike. not even a liter bike that comes factory with a 190. not to mention the added cost.

btw i have a 150 on my fzr400 not even possible to get to the edge of the profile. much to steep. thats with knee down and all. but tire brands and stlye are all different so profiles may be steeper then others.

traction problems with a smaller tire? look at the suspension first.

it will fit but i wouldn't recommend it because the 4.5 rim is a bit too narrow for the wider 180/55. the narrow rim will cause the tire's sidewall/edge to pinch in and deform the tire's profile such that it will not perform optimally. the 180/55 should be fitted to a 5.5 or 5.75 optimally.

Yep, the ss with the 170s and 180s use the 5.5" rim. Your profile will be wrong on the 4.5 and it won't work right. Get a replacement rim in 5.5 if you want the big tire look. Save money and enjoy the 160 if you just want good handling. You can get most all the good tires in 160

Stick with a 160 on the 4.5" rim. As Rick mentioned, the profile will be completely wrong with just a 170 (not to mention a 180). I've mounted up 170's before on the 4.5 rim, only to take them right off because of that issue.
Also, the ss already have power to weight working against them, 160's are lighter.

so I'm taking it that you just want the fat tire look?

even after all that all of these knowledgeable people have stated?

stay with a 160on a 4.5" rim. I run that on my Hot Rodded 95' CR..it handles so much better... save the looks for poser .my.02

you also save 1lb. of weight by running a 160 vs.180 [this based on Pirelli diablo weights]
less weight=better handling

180 on 4.5 = more weight, carcass deformation, significantly poorer handling

But, looks cool.

you decide, based on what you do with your bike. If you only do frapuccino runs, ignore what I and everyone else says and do what you feel.

you really don't need the extra contact patch provided by the 180 until you exceed 100 rwhp [in my opinion]

so, taking this idea one step further, does anyone make a lightweight 4.5" wheel for the SS? I see 5.5 and 5.75 advertised, but I would rather keep my 4.5"/160 configuration.

I have a 180 on my 97 SS and to be honest it looks a little too big. I'm going with a 170 when I change the tire this summer.

I looked around a bit, and didn't find any. If you are going to go with aftermarket wheels, 5.5 was the narrowest I found. I wanted to stick w/ the 4.5/160 also, but ended up going to a 5.5

okay, one more question and I'll stop hijacking this thread. If there is no lightweight alternative for the 4.5 rear wheel, is there really much weight to be saved by switching to a cast magnesium/forged aluminum 5.5 with it's heavier rim and larger tire? Correct me if I'm wrong, but didn't the '03 800ss come with 5 spoke wheels instead of the 3 spoke? did it have a 4.5" rear? were they made by brembo? Sorry about all the spastic questions, I've had a lot of coffee this morning.

the new wheels are made my marchessini, not brembo any more.

As of 02, I believe all of the SSs came with the 5 spokes.

One question I have then: Is the swing arm from the 750 the same as the 900? Will it even accept the 5.5" wheel?

this post is extremely hard to understand.

Can you put some punctuation in there for us?

you just have to flip the front sprocket [flush face out] it effectively shifts the countershaft sprocket line, out 10+ mm to get the chain line straight for the wider wheel. there is no difference in swingarms.
