The dealer may have been looking at the product data sheet(as seen here from the Pirelli website). In this, if you look at the Rear..you can see the 140/70 S has RIENFTL next to it whereas the 150/70 does not.

I believe(though I could be wrong) that this means "reinforced tread". It does have some bearing on the side wall, but from what I've read pertains more to the rubber on the road and the 'stickiness' of the tire.

While we ponder await more info on that, I have a quick question that I was discussing with dcappy this morning...If the new 250 is basically the same build bike with different grill and some extra buttons..I wonder if they actually went through the immense expense and trouble to change the rear hub bolt pattern and if not, can you just take the new 14" tires for the new 250s and retro fit them onto the old ones? I find it hard to believe that they would adjust the exhaust/support arm/ etc just to fit a new tire in.

I thought I'd add an update on my Pilot Sport 160/60 experience:

There's no rubbing on the shocks; it fits well and looks great.

As for the ride, I believe the increased width and different profile of the tire does change the bike's lean characteristics. For me this was slight, but my mechanic picked up on it straight away. Essentially, the wider flatter tire likes to stand up more and might require more effort to get on it's sides.

It's not a big deal, but I will surely try the 150/70 at my next tire change.

Anyone been in the rain on a Diablo yet? I'm still a little wary of that tire given the designer's rationale for the tread design (i.e. none in the center of the rear for stability under load, with deep grooves in the front to cut water off the road surface for the rear to following through). Obviously our 3 wheelers work counter to that line of thinking.

I rode in the rain plenty on the one on my 250. No problem. A little wet weather with the one currently on my 400 and no problem.

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.
Most motorcycles get speed reading from the front wheels. As far as the wheels going different speeds this has been dealt with in cars for years, they use the average.

In my experience the speed log on a car is in the transmission final drive and therefore is a single signal, vice the two apparent signals that must be crunched from two separate sensors on the Mp3 front wheels. Can't speak to really newer cars but I would be surprised if it had changed much. Never really considered or knew much about motorcycle speed indicatorsother than having seen a few mechanical devices on hubs before.

schifo: I was caught in a light storm the other day on my 150/70 diablo rear. It performed very well. The tread in person has very deep grooves. So, while there are not many grooves, the depth makes up for it in wet conditions.

Overall, my findings with the 150/70 are:

1. Ride height up by 1/2 inch.
2. Center-stand scrape is just gone.
3. because of the rounded profile of the tire, I have found that leaning over comes much more easily, and deep banks a very stable with much less rear jumpiness.

There is no doubt in my mind that this is the tire all 500s should have from the factory. The stocks really neutered the ride for me. i thought it was fun before, but now? Wow. Just wow.

I'm certainly considering it, as a new tyre is due on my Fuoco in an estimated 1000 miles.

Surely as soon as my 160/60 is used up I'm going to fit a 150/70. Being able to avoid dragging the center stand would be welcome. With the 160 I'm still dragging the stand and I still have 1/2 inch "chicken strips" on both edges of my tire.

And for those of you yet to go wider, I would recommend the 150/70.

That's the way I like my rear, fat and wide
Just got mine back yesterday with the Diablo 160/60 installed! Initial 4-mile test result: ride height slightly lowered, solid grip, "quicker" acceleration. Be back later with a more detailed review.

The Diablo is a *lovely* tyre. I'll be choosing a 150/70 though.

I like!
After a very casual 90-mile run (20% streets + 80% hwys) yesterday, I am pleased to say that the slightly lowered profile of the new 160/60 rear tire suits me well. I no longer experienced the forward-leaning ergo which was a bit bothersome while I was running the 140/70 (and I ran it for 8,150-miles). Now I not only sit lower, but it feels more stable and more comfortable (on my back). (*I am 5'10", with a 32" inseam)

Amazingly, the wider rear tire does not rub against the rear shocks at all, which is a real good news!

I love my new 160/60 Diablo rear!

MSG 150/70 - 14
Ok, so I've put about 150 or so miles on my new MSG 150/70 14. I'm not sure if it's much better than the OEM MSG 140 or not. It's different. She's quite a bit more sensitive to any and all steering input and a bit more "twitchy" is the best way I can put it. The biggest surprise to me however is how different the front end feels now compared to the way she used to handle. More of a "diving down" feeling when you lean her over hard. Also, it seems to require much less effort initiating a lean as well as pulling her back up. She pops up much faster coming out of turns.

In general I'm pretty happy with it so far. Maybe more break in is in order before I can really judge... It's not so different that I can't get used to it. It's just different. That's my report so far.

Got mine 150/70 pilot city today




totally agree with dkrz123 about scoot's behaviour. It became more lively and agile. Better lean in corners too) and raised tail is useful on the bumpy roads So I'm very pleased with it)

ps MGS lasted for 11k miles. After 600miles of weekend trip it is totally destroyed

burn it baby burn it. you'll be happy to ride with the Diablo 150/70. just make sure you have it on hand before you tear up the existing rear.

150/70-14 first

ditto.

Just don't want step two sizes up in one fell swoop without going the 150/70 route first. I'm concerned about the width of the tire near the shocks. It'll be interesting to see how different it feels with a 150/70. Most likely will make the move to it around the 12K mile service check in another 3 months.

Another thread seems in order as a kind of "reports page" on the Pirelli Diablo and new users experience with this tire. Different experiences of how the bike reacts with a slightly different rear tire size are starting to pepper a lot of these reports.

It appears that although advertised the 150/70-14 isn't in existence in the UK.

I may try a 150/70 MGS.

Just got my 150 70 14 Michelin, and in the short ride home I noted most of the things others have said, quicker turns, a little higher seating ( seems I am looking higher over my screen) but all these things are somewhat subtle and nothing too concerning. It hardly even looks very much different, so its amazing how little it takes to affect the ride.
I am curious to take it on the highway, and see if that seems different.
So far so good.

How else are you gonna find out? And throw in some twisties while you're at it.

Happy to do twisties, but the bike will ace that no doubt. It is the straights of a highway I was kinda concerned with, as the small wheels up front handle quick enough there already, I didn't want to get any twitchier.
I put a larger tire on the back of a vespa once, and it went really twitchy up front, changed it back pretty quick, so from that experience the highway was my largest concern. Seems it will be fine. Should know by tomorrow.

Lower is better
I guess that's why I am fairly satisfied with the recent change from 140/70 to 160/60. Now I sit a little lower, barely noticeable, about 2mm according to my calculation. Overall, after 100-miles or so, I would say it's pretty close to perfect (I am 5'10" with a 32" inseam).

Lower just might be better. I took it out on the highway, and it did just fine, but I do notice the steering feels just a little lighter, just a little less planted.
Highway is the least of my riding ( usually twisties and around town) so I can live with that. However, I always have thought the front wheels compared to a more normal wheel in the front require a little more attention as they steer quicker and there is less seeming gyroscopic effect at speed, so lighter steering there is not all that welcome for me. But it will likely prove even more fun on twisty roads, a trade off.

Give it a couple more days and you'll forget how the bike used to handle with the OEM 140 completely. I now prefer the more responsive nature of the handling as I feel more in control whether at speed on a highway or doing tight twisties.

I'm really enjoying my MSG 150/70 now. Had some concerns at first but I'm sure this will be my tire of choice from now on.

Old thread but hopefully you guys are still here. Are you putting 160/60/14 tires on stock rims? Just curious because I have a flat and going bigger sounds like the thing to do. Just wasn't sure if I needed a new rim as well. Thanks!

no new rim needed, a 160/60 will work but take into consideration your decreasing the height of the tire so scraping the center stand WILL be alot more.

There is life here! Thanks OAD. Not super concerned about that. It's annoying now, so it'll just be a little more annoying but hopefully with some benefits
