Tyres for a 750 sportsbike - July 2008

[mouldy]

well why don't you go 190/55, instead of the stock 190/50

best of both worlds

Because that size is only available in supersport or race tyres . Stay with the 190/50/17 on the R1 only on TLS,s do you gain by going 180 on a 6" rim .
M3s are good but Diablo Rosso's are better .

rosso's come in 190/55 (http://www.pirellityre.com/web/catal...IABLOROSSO.xml)


It was a race type of tire, but they are starting to be become more main stream, with people wanting the contact patch of a 190 but turn in on a 180

Ah, I see. I always thought that the profile in the tyre code was the sidewall (around cars for too long - new to bikes) - but indeed if you get a steeper profile I see how your turn in ought to be sharper.

I'd have a play with tyres if you have the time and money Mike... I remember not reading that long ago about one of the PB staffers that went R1 racing. Was halfway through the season before someone told him that the 190 was always ditched for a 180...

PB?

I'm not going to eat tyres just for the hell of it. I just want to try and get it as close to right as possible in the first go - then we can always try and improve from there.

Not in this country they don,t . Nationwide hasn't got any on order yet otherwise I'd be running one .

190-55-17 the "55" is the sidewall height. It will make your bike tip in because it will raise the height of the arse end of the bike by another 5% of the tyre width. Raised rear ride height.

Manufacturers choice the tyre size to be applicable to many different riders of many different skill types for most of the different purposes it could be used for a 180 may be better suited to some applications but unless your willing to play, stick with the 190, unless recommened by someone who knows how you ride and what effects it will have.

Get a sticky frount tyre dude, real sticky Sorry.

go the Rosso's cause I want to know what they are like.

[MIZXR]

I prefer the pilots because of the quick turn in, saves having to raise the ride height to speed up the turn in thus decreases the chance of tankslappers.

Metz were not all that fun on mine.

Also consider a sports touring on the rear insted of the stickier version, seems more usefull for the riding we do. Warm up is quicker and only becomes a problem at the end of a session in summer. Or on occasion to Akaroa on hot days it starts squirming everywhere.

When you ride like OAB or Bren then consider the super sticky

From what has been posted in this thread and what I have been told by other I'm pretty set on trying out the M3s.

Anyway, my bike has a 17"x6" rim and a standard tyre size of 190 mm. Now I understand perfectly that there is an amount of wank factor about fatter tyres (just like cars) - on the other hand I can't believe that the factory would put out a bike which is less than ideal just because of the wank factor.

So what are peoples take on this subject? What are the disadvantages of dropping down from 190 to 180 mm? What is the difference? I always get suspicious when people say "it'll handle better and it's cheaper too"... So what's the verdict on this matter?

what kind of bike?
"sport" riding I would sugest some bridgestone 016s, their pretty good in the rain too.
for commuting /weekend thrashes then pilot road 2s.
for just commuting then bridgestone 021s.(their slightly harder than the pilot road 2s but same type of tyre.)

I wouldn't.

But then I am struggling to understand how one would "go down" from a 180 to a 190.

If that's a 6 inch rim on the back, stay with the 180. Folding a 190 onto it may give the rear a markedly different profile from the manufacturers intention.

a 6 inch rim takes a 190.
a 5.5 inch rim like on my 750 takes a 180.

It comes with a 190 as factory standard. Then the question is, would it be better to go down to a 180 instead? I never contemplated going up from the 190

I have seen a 200/ /17 tyre, It was big...
usually if your bike feels to heavy for your liking and you dont want to play with suspension a 180 will make it feel lighter.
it will also be a bit flatter on the rim meaning smaller"chicken strips" for the same effort.

Now where is the fun in that?

Nah, I've decided to try out the Metzler M3s. I'll stick with the factory standard tyre size.

Cheers guys!

Soooo . . . what was the outcome? I've got a similar decision coming up!

Come on Mikkel, what say you..? two months worth of M3's.. we want to know (and what they're on too please, so I know if it's similar to mine..) what you think of them, how they wear, what the grip is like, and how hard you ride them..!!
