190/50 or 180/55, i thought the 180 would allow for slightly better handling, although the 190 size seems more common these days, was gonna go with a set of either Pirelli corsa III's or Diablo rosso's, anyone tried em?

I would stick w/ the stock 180. A 190 will slow the handling down immensely and the handling is the whole point of owning a Tornado :)

I have a set of Corsa III's sitting in the garage but haven't tried them yet. Have been running Pirellis on the track for years (slicks and SuperCorsa Race DOT's) and they run a nice balance between Dunlops and Michelins.

well i drive 190/55 Diablo corsa 3 it is as good as 180 in handling and as good as 190 in grip, may be this is the reason why it is the stock size on MV Agusta

I think the stock tyre for the Tornado is a 190/50 or a 180/55. It is only the LE that has the 180/55 fitted from factory. There is a missprint in some specs that gives 190/55. I assume it must be wrong as they come from factory with 190/50.
I have tried 190/55 on my Tornado and did not like it, the Tornado has a very high seat and the 55 tyre I fitted made it about 12mm higher.I personally would not recommend a 190/55 on a Tornado, but it may be good on a TNT.
I will prob try a 180/55 LE style next time.

If the wrong tyre size can slow down the handling, is it the width of the tyre, or the height, i.e. profile, which has most effect? In other words, would a 55 profile tyre turn as quick, whether it is a 180 or 190? In theory I would have thought that a 190/55 would turn in quicker than a 180/55, because the greater diameter would steepen the steering angle. So, where does that leave the 190/50? Discuss.....:D

Cheers

The 190/55 is the stock tyre for the Tornado. They were shod on Dunlop 190/50's as they were a cheap deal and dunlop dont make a 190/55 in the D207. A 190/50 is perfectly fine to use but will slow the steering down over the 190/55.
Fitting a 190/55 will raise the bike by 9.5mm. If youre short in the leg, back off a bit of preload.

It's about the profile of the tire, you want the largest contact while at full lean, not while upright.

180/55 is: 180mm wide - 99mm tall
190/50 is: 190mm wide - 95mm tall
190/55 is: 190mm wide - 104.5mm tall

A 180/55 is a great tyre for a sportsbike, turns quicker than a 190/50 and has more contact patch at full lean. Why you would fit a 190/50 ? :doh:

A 190/55 is an excellent tyre for the Tornado iif you are ok with the height. Nice and stable, turns quick and good contact patch whilst cornering.
The taller the tyre the more theoretical side/lean angle grip you should have.

I used a set of 180/55 Corsa III's for a blast around the Pubic Isle last year and was most impressed. Got 5,600 km out of it (6600 out of the front). I'll definitely use them again.

Running 190/50 Rosso's now - asked for 180/55, but the shop stuffed up. They don't turn in as quickly due to the fatter size, or instill you with the grip confidence the Corsa III's did, but they're still excellent, have already done 5,000, with a few thousand to go. Curiously, the rear will outlast the front.

That would be why I feel that mine is slower turning in, and tends to run wider mid-corner, because I have a 190/50 (Diablo Corsa 3) fitted. I may try a 190/55 next time, to feel what difference it makes.

Cheers:D

I think mines still on the original pair of Dunlops at 6000 miles not bad I found them to be nice and stable....Has anyone used Continetal Road Attacks ? I don't want mega stickies I prefer value oops longevity :)

No, but, if you want a hardly worn original front D207, I've got one going cheap....:D I'm coming to Sussex in 3 weeks....:D

Ian, I hope you dont mind me carrying on with this dispute;) , but If you are taking the size from the manuals,it is missprinted . It does say 190/55 but it also states 73w. A 73w is a 190/50 or 180/55. A 190/55 is a 75w type.
If you check data from Benellis web site the sizes I say are stated.
The LE only gives a 180/55 and it has a narrower rim than the tres (5.5)(tre6)

Colin, Having refered to the workshop manual, as opposed to the owner's manual, I can see where both you, and n33ly are coming from. The owner's manual states 190/55, while the workshop manual states 190/55 (/50 fitted)ZR17 (73W). The latter appears to me to read that they fitted what they wrote in brackets - (190/50)(73W), as opposed to the 190/55ZR17, which was the original design specification tyre. That bears out n33ly's theory that the D207 190/50's were fitted for convenience, and also, why you believe that the original rear was a 190/55. It was, but it wasn't intended to be....maybe:D .
Most people seem to be happy with a 180/55; turns quicker, larger footprint at full lean, etc, than the 190/50, and the 190/55 should give similar characteristics, whilst raising both the gear ratio, and the seat height, the result of which would be to steepen the steering angle for quicker steering, but more twitchy.
You pays your money and takes your choice, I reckon, but it all seems to leave the 190/50 out in the cold. Unfortunately, I have heaps of tread left on mine yet :doh: .

cheers,
Ian

+1 on that Ian

The Tornado was designed with a 5.5" rim (180/55) or a 6" rim (190/55) and as you pointed out, these tyres share very similar characteristics.
The 190/50 is a cheaper tyre than a 190/55 - that's why Benelli ended up fitting them.

If you prefer a 190/50 with slower steering characteristics and less grip at full lean (but more upright) then go ahead. I suppose it depends what you use the bike for.

That is why I ended up with a 190/50, I guess. I bought them as a front and back tyre deal; 190/55 wasn't offered in the deal, although there was an option of a rear 180/55. I went for the 190/50 because that was what was originally fitted. I should have guessed....:doh:
This forum is great, isn't it? :clap: :clap:

I would stick with the 190/55 as 190 section tyres are designed for a 6 inch rim. 180's are designed for a 5.5 inch rim. You can fit a 180 to a 6 inch rim but as the wheel is half an inch wider than the 180 was designed for it will "flatten" the profile slightly.

A 180/55 on a 5.5 inch rim v's 1 190/55 on a 6 inch rim will share an identical profile but the 190 will have a bit more shoulder. Both will turn in the same and be equally as stable.

If you fit a 180/55 to a 6 inch rim it wont turn as quick as a 190/55 on the same 6 inch rim.
