I sure hope I picked the right tire. I measured the 160 today and I think it will fit. I won't put the tire on for a couple of weeks yet. I hope it fits When I do I will take pictures and post.

measuring off the rim will not give you accurate readings as the size will increase after inflation.

OAD

I kind of factored that in and it will be a tight fit. The only way to know for sure is to put that bad ass tire on and see. The tire itself seems huge and the only way of knowing is to put it on.

antdaddy in sacremento posted he has a 160/60 you might pm him for some pics and clearance measurements just to be safe. Also have him look at the springs just to check for rubbing.

Diablo rear tire update
Today I rode with Luthor down to Chattanooga for the first ride on my new rear skin. Going down I took it pretty easy on the corners just scrubbing it in Ya know. On the way back I got more agressive with it and man does it corner nice. When we stopped for gas both he and I noticed my tire was quite a bit taller than his MGS and looking closer my new rear gave me atleast 1/2" or better of more ground clearance . On to the the settings. I road it with 34 lbs press shocks set on the 3rd hardest postion and my wieght is 185 . I will keep the press where it is at as the grip and side felling was very good. I would reccomend this Diablo 150/70 as a great replacement for stock GTS 24 or the MGS.

I just got a 160/60 Pilot Sport on my 500. Fits fine and rides great. There's about 1/8" gap between sidewalls and shocks. The extra height OAD mentions is a strong point for the 150's, though.

Well, here's a shot. Apologies, I'm not much of a photographer, and this shot was intended to capture the LV exhaust. Maybe I'll try to take a better pic tomorrow. Worth noting, my 160 is a Michelin Pilot Sport (my fronts are the same and I decided to match them). I measured the gap between the shock and sidewall to be an 1/8". I've ridden it for a couple of days and I've yet to detect any visible signs of contact on the shocks.

It looks great and rides swell. I do like the added height that OAD talks up on the 150s, though....

reno the pilot sport is not even close to the Diablo. I have yet to see any pics of a Diablo 160 mounted and installed so you'll be the first to hopefully post a pic.


edit I just reread the entire post and saw AK had posted a pic of his 160/60 , so hopefully it will work for you.

Thanks for the photo.

Just a request: Would someone please take a photo of the "gap" while a rider is seated on the MP3, suspension locked and loaded down without the center-stand?

That's what I am hoping for. When I take the pic's I will have the 400 up on the lift so I should be able to get some good close up shots.

Say, this isn't particularly to me in southern california where it seldom rains but it might be to others...

The Diablo rear tire was designed with scant tread in the center; the front one has a lot more in the middle. The thinking behind it was the front would cut a path on wet roads that the rear would follow through.

Does this pose a problem for our 3 wheelers?

here are a couple of pics of the rear shocks compressed with the Diablo 150/70.

the clearance is good, approx. 3/16" on both sides even thought the pics look worse than that. I am good with the amount of clearance as to not ever have a shock rub issue.

Ok 160 on


Ok today I installed the 160/60-14 Diablo. Here are the pics. I haven't had a chance to ride very far but it feels really nice. The old MGS was wore out and the back end feels really planted now.

Right side.


Left side.


Without muffler.


With spring a little compressed.

Fantastic!
Thank you so much, OAD, those loaded suspension shots really tell how close the rear tire is to the springs. Great job!

reno bob, the 160 looks awesome on the 400 and happy to hear that you like it so far! Just wondering how close would the rear tire come up to the springs with (you) the rider sitting on it without the center stand?

The 400 is sitting on the floor of the lift. I attached the the straps and sucked the springs down to about where thy would be when I ride. The 2 close up shots of the spring and tires were taken then. The tire is close to the springs but I think that there is enough room that they will never rub. I really do like the Diablo. Just put 1 on you won't regret it.

Thank you very much, reno rob! I know you're right about the Diablo. Personally, I've had great experience with the Diablo (on a different scooter). That's why I'm having a 160 fitted to my 500; but it has been sitting at the local Vespa dealership for a week and a half now, and they haven't gotten around to it yet...?

The rear wheel on the 400 is much easier to change than the 250. No messing with brakes or hub nut. Remove the wheel yourself and take it and replacement tire to any reputable motorcycle dealer to mount the tire. They will do while you wait and will probably save over $50 in labor cost.

Fuzzy

There is a hub nut on the rear of the 400 and there is a sealed bearing on the swing arm that you have to remove. The 400 is easier than the 250.

Of course haven't done it yet but told the swing arm comes off with the hub nut still in place and then the wheel can be removed from the hub leaving it and the brake disk in place, more like removing a car wheel once the swing arm out of the way. Didn't got too far into it as I have another 4,000 miles at least I hope before I need to do it.

After reading Old as Dirt's comments on the 150/70 Pirelli Diablo, I'm sold. The half inch of extra clearance in the back means less scraping of the center stand! Yay! Just ordered today. I'll go to 160/60 maybe later, after the brave souls who run them put in their $.02.

on an unrelated note, I only managed to pull off about 3200 miles on stock.

My Mich Golds lasted around 5K but they were pretty shabby toward the end performance, looks, and handling wise.

I may have said this already, but take a moment and clear your mind of numbers, weights, statistics....you can LOOK at the Diablo 150/70 on the rear and instantly say in your head "Damn, that tire is a lot better". It looks better, sits higher, had better tread depth and placement in my opinion, and is just all around a sharper looking tire. It really almost promotes the rear end to MC status. I have one on order already and I showed OAD my new Dennis Kirk catalog where I found Pirelli Diablo 12" 130/70 FRONTS! My mouth is already watering at the prospect of having all Diablo...

I got happy for a few secs...
I got briefly excited from reading the last post from luthorhuss, then the doubts set in. Checked it out a little further and came up with less than good news.

You know the photo of the Diablo on the DK page shows a rear (I know, I have two; yet it turns out the 12" they make it's actually a rear), and therefore misleading since us mp3 owners would think that it ought to (and it may very well) fit the 12" front wheel, right? Regardless, I just don't feel all that comfortable putting rear tires on the front, you know. The engineers hadn't intended for the rear to be in the front, right?

The Diablo front should look more like this:



Still pretty incredible with groove pattern that looks like lightening! Finally, I do agree with luthorhuss 100% that the idea of an all-Diablo-equipped MP3 500 would be awesome in every way! Only wished that they would make a 12" front to go with it, NOW!

p.s. my stock michelin gs rear had over 8,000 miles on it with rapidly fading performance (especially frightening in wet); so it is only fitting that it is now getting a Diablo 160/60 installed. pics after dealer finished the job, but for how much longer, they don't know??

Thanks for the dig, luthorhuss!
Like's:
    1. At least it's available for US buyers @ HelmetHeadCity.com
    2. Finally, Diablos all around. Cool!

Dislike's:
    1. Withholding the 12" front on the US Pirelli site (what, Americans don't deserve a little performance)?
    2. Front costing as much as I paid for the rear (160/60-14)?
    3. You gonna need two of these.

update on rear tire
no rubbing at all. its functioning perfectly. actually even better than stock tire for performance/comfort reason as described in my previous posts but also the rate of wear on the bigger tire if a fraction of what it was from my stock one...all around I'd recc the upgrade to anyone with a MP3500 (that is after the j costa...)

i also recently painted the foot floorboards black also. will try and post picks when i have time.

the tire upgrade to me is more important than the vari as that is what is sticking to the road and traction is more important than performance.

You must have great tires first
+1. Without high quality tires, much of the performance would be lost before it hits the road. You get more bang for the bucks by upgrading to the Diablo.

I plugged the three tire sizes into a spreadsheet and got this result:



Looks like the 150/70 will make the MP3's "optimistic" speedometer a little more accurate, and the 160/60 ever-so-slightly less so.

Anyone who wants to check my code can download the Excel file here.

Ramblerdan - surely the 150's wont do anything for the speedo as the speed is measured from the front wheels?

It will, however, make you just that little bit faster!

From the front wheels? You end with a question mark so is this the case? I did a quick scan of the shop manual... perhaps the "tone wheel and tone ring" is an encoder for speed (page SUP-6)? I'm curious now as to where the speedo picks up.

EDIT: Just reviewed the wiring schematic and in the lower right quadrant there are two devices drawn and named "left speed sensor" and "right speed sensor". The drawing is a somewhat pictographical representation of a rotary encoder so it appears likely the speed is determined from the front two wheels. Which is rather intriguing in that there must be an interesting algorithm that interprets the speed pulses from two sources and outputs one indicated speed... Perhaps this is why the speed registered and displayed is incorrect, except at zero!

Since it is evident from the schematic that speed is determined by two sensors, and there are two front wheels, logic dictates that displayed speed is gathered from such; hence, the rear wheel diameter should not affect registered speed. Nice catch, Steve.

The 150/70 diablo is on the monster. Soooo nice. That height difference really helps with the "center stand scrape" issue while dragging corners. One word of warning, however: my dealer mentioned that the diablo does NOT have a reinforced sidewall, and under extreme conditions (extra weight, extreme cornering), the bead might break. He could be full of it, but that was his word of warning.

I did some extreme corning on the Dragon last week and the diablo hooked up great. no scraping and I was fairly aggressive on the corners. I think your dealer is off base alittle as all tires have to have reinforcment in the side walls as otherwise the rubber will blow out just under normal air pressure.
