Anyone changed profiles to a 190/55/17 and got any feedback? Also do they have enough clearance on the rsv? Looking at a set of metzeler racetecs.

Cheers

I used to run a 190/55 and apart from the fact it was about 9mm taller and altered the gearing it fitted under the hugger ok and actually gave more chain clearance.

Since going back to a 50 profile I find the chain nibbles delicately at the corner of the tyre. Confused

I've not heard a bad review or opinion on going to a 55 profile.

I've read a few people run 180 width tyres. What's the crack with that and are they any good and better than the 190's on the rsv's?

180 lighter and has a steeper profile as is the same height as a 190/55 but 10mm narrower. Gives a quicker turn in and helps with direction changes.
 
180 or 190 in 55 would be my choice.

I've got a 180/55 on my 2001 RSVR. Was standard fit by Aprilia on the 'R' as opposed to the 190 on the standard bike although was also fitted with the Super Corsa tyre (Dragons in the day). The theory was that the narrower tyre gave a better turn in than the 190 but of course the more pronounced 'V' profile of the tyre would help this also.

Edit: Spoonz beat me to it.

I have power pures on mine in 190/55 and they run very close to the chain as in probably about 1mm away and it has a 520 chain, but different brands do come up slightly different sizes,just like when i order new jeans,i order the same size but they are always a tighter fit? but i do prefer the 55 profile over the 50.

Apologies for sounding stupid but will the 180 have to be stretched to fit on the wheel on my 03 rsv? So what size would be best a 180 or 190 :s

Cheers guys

No
 
180 was a standard fitment on all Rsvr's for quite a few years to speed up the handling as 190/55 were few and far between back then. A 180 is designed to work on a 5.5 or 6" rim which is what u have.

It's purely a preference issue as there is nothing stopping you running either.

Never tried a 60 to give a valid experience but the 55 works fine for me so have no reason to go higher.

180 - 55 is common size in all sports tyres a 180-60 is a racing profile and mostly only available in trackday tyres. Supercorsa SC's, Metzler Racetec K's, Contirace attack's etc.

So generally, picking a 180-60 is more about what you need the tyre for, it will handle better for sure, but track tyres don't warm up as fast, generally awful in any wet condition. if you only wanna ride on nice days, happy to go easy a few miles to get the heat into them, go easy after a slow pass through a town etc but want phenomenal high speed dry grip and razor handling..

If you want quicker warmup, sustained grip even on slower sections, safety if a shower lands, etc.. buy a good sports 180-55, like a sportsmart2 or Metz M5/M7, Bridge S20's, sport attack

So is the consensus that a 180/55 is better then a 190/55, which is better than a 190/50?

I'll be due new tyres before I go to the Alps in July so want to make sure I get the 'best' size Thumbs Up

I haven't tried a 190/55 but I went from a 180/55 to a 190/50 and I hate it Thumbs Down Have only got a few hundred miles on it but am going to be changing it in the next few weeks.

There is no best size 180 or 190. Some prefer one and some the other. The 190 has a bigger footprint but is heavier and wider so a different profile to the 180. The 180 will turn quicker but maybe have less ultimate grip in theory.
 
For the average Jo it's likely to make bugger all difference technically to be honest. Tyres are as much a phycological advantage as anything else. If you think your tyre is the dogs you will push it a bit more but in reality you could probably push a touring tyre just as much but your brain tells you not to.  It's easy to overthink it when really anything half decent is likely to have more grip than the average rider can exploit.

Also consicder that riding above snow lines means your on Shell Grip tarmac which is like sandpaper. The last 2 years in the Pyrenees i have gone through a front tyre per trip usually on the right side and not on sporty rubber. We even had to get a rear changed in Andorra on one bike as it destroyed it down to the canvas. If you run a super soft sporty rubber the tarmac will eat it very quickly.

Have been running Metzeler Z8 190/50, and I think I can say that the difference going to 190/55 was considerably noticable. Quicker turn in, and the bike did not want to straighten up as much as before. I know the Z8 is a sporty touring tire but it works very well in my area. We often see a bit of rain, and temperatures is mostly between 10 and 15 celsius. Never had any close calls. Also, it delivers decent milage.

While the 55 is more round it's more preferable for track, if you driving mostly road etc. the 50 tire is having slightly more long mileage.

I'm running now with 190/50 but while I'm a bit (too Cool  ) sophisticated with the weight my next choose is 180/55, maybe I'm then a bit more better driver too and can use tire more wide LOL  .

180/55 is better than 190/50 but also runs out of lean angle a lot earlier than the 190/55, and for that reason alone I now run the 190/55.  The rear and front chicken strips now  fade out  together.

Just check the clearance between tyre and swing arm.

Last Trackday, a guy in our garage kept getting black flagged for smoke from his bike, every time he pulled in, no smoke !

Turned out the tyre was expanding when warmed and at speed, and was rubbing on the swing arm at the front, but cooled and contacted when back in the garage, so rolled freely.

And extra link in the chain required....lol
