Here in Italy, that Ducati document has no worth, so it's no way to ride legally a Paso with tires different from 130/60 r16 and 160/60 r16...

That`s the most stupid thing I ever heard but italians are known to make their own life difficult

I'm glad we don't have to deal with that legal B.S. here in California

I wonder how many accidents happen because guys who don´t know if a bolt tightens clock- or counterclockwise do modifications on their vehicles.

Swing arm changes include 3 basic mods

mod 1 change to a 907 swing arm( or similar 17 inch swingarm)

mod 2 Skins picture of a modded cross bar

mod 3 cut and lengthen the 16 inch swing arm

Anyone have anything to add ?

Higgy, are you referring to 16" alternatives ? If so mods 2&3 can be avoided with the halfrings which would be option 4. That´s less radical also.
Mod 1, is the easiest if you do a 17" conversion as it`s plug`n`play but if you keep the 16" wheel it`s the most complicated option as nothing will fit. I`m probably the only one who did that keeping the old wheels as IMHO it`s the most elegant solution and one could swap to 17" wheels in 30 minutes. If you combine a 907ie swingarm with the 16" Oscam wheel you`ll need new bearing spacers due to the different diameter axle (the ones from a 750 Sport can be used), then you`ll need spacers to center the wheel and at the end you`ll notice that there`s a problem with the brake as neither the the caliper bracket of the Paso nor the one of the 907ie can be used (first won`t fit with the swingarm and axle diameter, second not with the 16" wheel and the bigger brake disc - 270mm instead of 245mm). As the 907ie swingarm is slightly longer the bike will become a little higher and hence the stands too short.
Another positive thing though is that there won`t be any tire-swingarm clearance issues anymore and it still looks good.

I have two Dunlop D205 180/60-16 tires and they have a considerable lip/width that probably requires more than just a 1-2 mm grind off the side. This is the main reason why I'm attempting the sprocket shim - so that I am not limited to only one brand tire. If my machinist will quit over-heating the rear wheel spacer and warping it while turning it down during his lunch break, I'd have the bike back together and tested, already. I can't complain since he does everything for free.

If spacing the sprockets outward ends up to not be very feasible, then I will probably go with the Shinko, as Mike has done, and then, if Shinko discontinues that tire or changes the profile, I'll do a 17" conversion.

This would mean that the order of my attempts on the tire crisis that we 16" Paso owners are having would be:

1) Space out the sprockets for any brand 180/60-16" tire
2) Use a Shinko 180/60-16" with ground side lip for clearance
3) 17" wheel conversion (with 907 swingarm that I already own)

I believe any 130/70-16" front tire works with a fender shim, and Mike has a tried and true solution with the Shinko tires, if you don't mind taking a grinder to the tire. This is probably the quickest and easiest "fix" for anyone to do - if it is legal where you live.

I will try a very sharp razor knife to trim mine

For trimming rubber, either use a wire wheel on a drill motor, or a surform planer.

They work great for rubber. Avoid the temptation to do this with the motor running, the bike in gear an on a center stand. That technique has created disaster before unless you have someone at the controls.

WTF is wrong with you guys..... Either everyone has an engineering degree and works for the govt which makes it necessary to make everything so freaking complicated to justify the wasted years of your life you spent in college to learn nothing..... or have taken so many yoga classes that you think having your head up your ass is normal.

It's this simple, put tire on rim, remount on bike (yes chain and all), wait dont take bike off of rear stand yet.... get out regular old trusty angle grinder like this one - http://www.makita.com/en-us/Modules/Too ... ?ID=316402 Have a friend ect... spin tire by hand at an even and consistent speed while you grind off enough rubber to stop the tire from contacting the chain, (yes just use the normal freaking grinding disk.... yes the flat surface of it you douchebag) then grind off a little bit more just because I said so. By the way if you and your friend are dumb enough to do this without eye protection on good, maybe you will learn that you should by losing a freaking eye.
Now take bike off stand, put on your riding gear and ride the damn thing.... no don't bother looking at the thing again and re over thinking it, just lube and adjust chain, and keep proper air pressure in the tire.... if it rubs a little so what that will keep that side of the chain clean. JUST LEAVE IT ALONE NOW UNTIL THE TIRE WEARS OUT.

So in short only these things are needed -
1. New Shinko 757 180/60-16R
2. Rear stand
3. Angle grinder with grinding wheel
4. Common Sense

I understand that some may be offended by this post, those will be the same ones who do not have #4 in the above list. My suggestion to them is to sell all motorized transport in there possession and utilize mass transit as a favor to the rest of us, and for the saftey of society in general

Terry, you must be already a year behind. Why not take an old sprocket and turn it down?

Talking about the side and center stand. This is my bike with the 180/60 Avon when the original swingarm was still in. Only one foot of the center stand touched the ground. On the side stand the leaning angle was quite extreme.

Thank you. Actually, the 180/60+ 130/70 combo is way too wide a set of tires to have for a nimble Paso. The original front tire was too wide for decent cornering, and the original rear fatty undermines the bike's cornering as well. Slimmer tires do make the 750 Paso corner better and accelerate faster out of them. I've got over 1500 amazing miles on my Michelin Pilot Sport 120/70 + Pierelli Diablo 140/70 rear and the Paso is better than ever. These tires wear well, they are soft, and the profiles are excellent. Also, they are inexpensive tires (about US$60 each) so I've picked up another set Thank goodness I live and ride where I can run whatever tires I want to. To me 'scooter' is not such a dirty word anymore. O.K let me have it, I have my Tyvek suit and safety goggles on. Best Wishes, Randy.

Do you have fitted them on the stock rims?
So, are you speaking about scooter's tires? What speed do they allow with its homologation?

no further comments on the rest

Obviously some here are way to concerned that others may choose a different solution than they have. It's obvious from the input of others that several alternatives exist. The idea should be to present known alternatives and let everyone decide which solution they favor, without ridicule. Some people are offended if others don't follow their example. That's silly and immature. And yes, I do have an engineering degree but it's not required for this situation. Lighten up guys, life's too short to sweat the little stuff...

The idea I had was to put all the variations into one post,all comments are welcome and don't worry all will get sorted

It`s not about that at all. There`s only a small number of size alternatives if you think about reasonable ones. If you say you ignore manufacturer recommendations for use or max. rim sizes (which have a reason), if you don`t care or don`t know about a tires speed index, the weight index and their coherence there are as many alternatives out there as you wish not mentioning slicks which someone long time ago seriously suggested.

Well...now that you mention it.....Mechanical Engineering major for four years at Clemson University from '87-'91, worked in a couple of engineering departments for several years, and I am now working in an R&D facility for General Electric. Throw in I like a fun project that has a little bit of a challenge to it, I have multiple bikes so one out of commission for a while is not a big deal, and I've been accused of being borderline insane - why else would I be in the middle of this project?

Naw, no offense here....some of us not only view riding motorcycles as a fun thing to do, but also screwing around with them and tinkering is sometimes more enjoyable than riding them. I do like your no frills solution to the problem. It is probably the absolute best alternative for anyone who is not mechanically inclined, has the Paso as their only bike and doesn't want much down time, doesn't have some of the resources available to them as some of the others on this forum, and just want the quickest and easiest solution to reshoeing their Paso.

The only spare sprocket I have was butchered by a previous owner with a hole saw who drilled holes that were not spaced the same or even at the same radius. I just didn't want to have a screwy, jagged spacer on the bike, and my freebie-machinist wanted it to get the mounting holes properly spaced. If I really wanted the part by now, I probably could have it, but I've got too many other projects going between work and home....not to mention the graduate classes I've been taking.

Hey Randy
Ethan here . . .
I was just catching up on this ever expanding topic and read your posting on your experience with you tire choices. I know the weather has been Sh!tty these last few weeks BUT I gotta see your setup. So if you plan your weekend rides more than two minutes before hitting the road let me know when you might make it up here to Tomales - if not maybe at some point I can drive down to the City and drop by (with my digital camera and notepad).

I'll PM my home number:
