180 rear - R1

[R1GEEZA]

iv just had a pair of diablo rosso corsas fitted on my r1 after being convinced to try them. however, when gently scrubbing them in and checking how much lean angle i still had left i noticed the rear was fully scrubbed rite to the edges yet the front still has 10mil chicken strips.... i thought this was a bit odd and after double checking i realised thed fitted a 180 on the rear....... wats up with that? im thinking about going back and asking them to swap it for a 190 at there cost as i did ask for a 190. is this a mistake by them or what? i thought id ask for some advice before i go and make a fool of myself at the dealer lol
any input appreciated....cheers

Well if you asked for a 190 it is what should have been fitted. Probably a simple mistake at the shop as the 180 is so standard on bikes now. If you have a good relationship with them it should not be an issue to have it changed.

I once had a shop go down from a 130 to 120 rear as the 130's were out of stock (yeah it has been going on for years) it pissed me off during it's entire life (which I shortened with a burnout :innocent:) only because it looked 'skinny'.

I've noticed every bike wears it's chicket strips differently some fairly even front/rear bit most leave more rubber on the edges of the fronts.

How did you find the 180 over a 190? In theory it should turn in quicker.

yea it definatly turns qicker but because its a 180/55 rather than a 190/50 that was on the bike wen i bought it its hard to tell how much the width alone is affecting this. to be honest i like the fast turn in i was only worried because of fear of low siding due to over doin lean on the rear or it spinning up on corner exit? how common is it to be running 180 on a liter bike?? im still abit uncomfatuble with it and need to make up my mind befor i put any more ks on it. sumhow i dont think theyl be swapping it if i take it back to them half worn! lol its the first time iv been in this particular shop but they seemed very helpful and plesant at the time but in saying that who isnt wen ur handing ova a fistfull of ya hard earned! on the fence........help!

It'll be fine. If you're happy with the turn-in, sweet. If it's fucking with your head, get it replaced with a 190.

[White trash]

190/50 is a hprrible shaped tyre which will slow the steering. I rode for years on 180/55 on my thou's and 750s. Later, when 190/55 tyres became readily available, I switched to them. 180/55 will also probably give you more edge grip then the 190/50 but less straightline footprint. I also found the 180/55 to wear better.

Agreed. I run 190/55's now and find them to be excellent.

[R1GEEZA]

thanks for your imput guys. think im going to go try get it changed, even if its just a mentel thing i dont want it fuckin with me for the next how many thosand ks. fingerscrossed!!!

[White trash]

At the risk of causing offence, which is entirely not my intention, if you expect to get thousands of kays out of a rear tyre on an R1 then the size of tyre you have is not going to be noticeable.

That being said it's best to go with what's comfortable.

[R1GEEZA]

no offence taken and your rite, i dont know how long theyl last i used to run supercorsas on my duke 748 and they didnt last long but am hopeing to get more out of these. at the end of the day 500k or 5000k if it doesnt feel rite i dont want it end of story

[NZsarge]

Lovin' the 190/55 on the back of the ZX14, its a good step more fluid to ride now.

I have never purchased tyres for a thou, but I think if you are going to track your R1wouldn't you want 190/55 not 190/50? Just asking the hoards of experts on here?? haha,

If ur bike came with 190/50 maybe the previous rider was looking for a high milage tyre rather then a elbow on the ground, power slide that bitch "my tyre lasted one session" kinda tyre

haha yea i didnt like the 190/50 but wanted a 190/55 not a 180/55. this is really pissed me off cuz i dont know how long it goin to take to get it sorted and i wanna ride as much as poss while i got time off work........

[Quasievil]

I got me a 200 on the back and its awesome, cant get it to the edge tho.

[jrandom]

I second (third? fourth?) the 190/55 recommendations. Not so good if you do a lot of motorway miles; the pointy profile squares off real quick. Brilliant to ride on, though. Tippy and grippy.

Just go thrash the 180 until the shop opens up again and then get them to sell you a 190/55 at cost.

[R1GEEZA]

thanks for all imput. i think the overall verdict is go with the 190/55 which is what i wanted to hear! why would the use a 180 if a 190 is wat was designed for the bike!!! duhhhh

[miSTa]

Interesting of all this talk of the 50 vs 55 for the 190, hadn't really considered the difference that much before.

This image says it all (borrowed from http://www.sportrider.com/tech/tires/146_0302_rear_motorcycle_tire/index.html)

Shame I've just bought a 190/50, maybe next time.

No one has mentioned it but is a 180 not standard issue for those older R1s ??? Check a manual. ( Just asking I don't know )

Nah, they were a 190, same as the Gixxer.

I've previously run PR2 190/50 on mine. I changed to the 190/55 yesterday. Shit what a difference. Nearly have to lift it back up from the corners. It just falls over when you head into a corner. Marvelous.:woohoo:

Amen brother, I won't be going back to a 50 series if I can help it. Didn't make that much difference to the overall gearing either really according to my GPS, actually my speedo is now slightly more accurate.. :niceone:

Cheers bud, my 06 runs a 50 profile standard.
I'd benefit going to a 55 ? Must say I preferred my bandit with a 180.55, when I tried a 190.55 it seemed to over tyre it. Maybe just my preference.

Pretty sure the GSXR rear rim will be wider than the Bandit rear Gaz so you probably wont get that same "over curled" feeling.

If you wanna go stupid, get your hands on some 195/65 N-Tech rear with a 125/80 front. That makes em steer pretty fuggin quick :)

Based upon my experiences yes.

Going from a 180/55 to a 190/55 would slow the handling down I would have thought, probably not beneficial on a Bandit.
The benefits are coming from 190/50 to a 55 profile, the bike will turn more fluidly/easily and should feel more planted once leant over in a corner.

Poser:bleh:

[R1GEEZA]

went in to the dealer (yes bike dealer!) today and told him of the situation. luckily some 190/55 arriving tomora so they gonna swap it ova. apparently he spotted the mistake before i picked it up but because they had no 190s he left it!!!! not quite sure why he admitted that to me??? although i cant go for a ride now overall im happy with the outcome:woohoo:

something i only resently leared was the second number on the tire ie. 50 or 55 is a percentage of the first. so surely there isnt much difference in turn in speed goin from 180/55 to a 190/55 (55 percent of 180=99 vs 55percent 190=104.5) you just get the benifit of having more tire???? this is totaly just in my head and i could be, and probably am getting the wrong end of the stick??????

From the the (admittedly minimal) understanding that I have of it is the if your bike has a standard fitment 190/50 (like mine) and you go to a 190/55 (like I just have) you'll get a very slight sharpening in the geometry in the front end of the bike because the higher 55 profile has raised the rear of the bike ever so minimally but the biggest noticeable change comes from the fact that the the shape of a 50 profile is different to that of the 55 profile tyre.
The 55 is rounder and higher and rolls from side to side much more fluently than the 50 profile, the trade off for this is a slight reduction in straight line stability.
Going from a standard fitment of a 180/55 to a 190/55 (which i'll admit I have never done) would slower the turn in of a bike down making it feel lazier or slower to bank over into corners and slower to flick through from left to right (or visa versa) corners. Yes it would though have a greater contact patch once banked over into a corner, the only thing I would be weary of (particularly going from 180/55 to 190/50 or 190/55) is I guess it could introduce some kind instability into the handling somewhere.
You must understand these are only my thoughts and theories on the subject through a little of my own trials, there will undoubtedly be others out there that know much much more about it than that can back it up with known fact so take what I have said with a dose of salts, it's only what I have experienced that i'm relating to and relaying here.

Yes Sarge, instability was increased but mainly cos I had also raised the rear 25mm by fitting a gsxr1100 shock. This was a great mod for me, but the addition of the big rear 190.55 altered things just a bit too much. Inducing some fearful wobbles.

Holy crap, 25mm is getting pretty radical!

What's up now?

[R1GEEZA]

haha sorry. i just dont think i explained wat i ment very well!!!
i was on the same line as you as regard the difference between a 190/50 profile vs 190/55 profile but wat i was trying to say was 180/55 should have the same handleing characteristics as a 190/55 as they are both 55% tall as they are wide. i dont know if this makes anymore sence???? lololol

[roogazza]

Holy crap, 25mm is getting pretty radical!
Here's the beast, you can see the high arse.I thought it handled pretty well.227434

[Owl]

Keep in mind that tyres may vary substantially between models and manufacturers.

As an example, an Avon VP2 Sport/SS 190/55 (180mm) is narrower than the VP2 180/55 (181mm), yet has a larger diameter.:scratch:

WAT THE HELL!!!! took bike in this morning. wen i came back they had put a 190/50 on it....... wat is goin on? how hard is it??? i know i might hav a slight accent but ud think i was talkin fkn russian or sumthin.... aparently there are no 190/55 in the country. hav been promised my next set of tires at cost with free fitting tho. i give up!:argh:

What brand? I just fitted a pair of Michelin Pures to my bike, 190/55 rear, $468 fitted to rims locally.

[R1GEEZA]

pirelli rosso corsa mate. 600 bukka too! if id known the rigmarole id be facing i wouldve gone sumwhere else. keen for that ride tomoro?

Jeepers, so I'm guessing you are walking a bit funny this evening?

Darn good price.

[AllanB]

Bike tyres - they fuck with your head. You spend ages deciding what brand, style to fit, agonize over the horrendous price and hope they live up to your expectations.

Car tyres - you go to Tonys or similar and haggle over the price of a set of hoops and get 4 of them for 3/4 the price of 2 bike tyres and the car ones will last 30 -50,000 kms! Plus the car tyres can lose 30% of their air and not spit you off the road!

Can't make it tomorrow, got my two girls with me until lunchtime, then I'm off to pick up some new toys for the bike that are waiting for me at the courier depot.


Holy hell that's a bloody good price! Special deal?

I thought so, but I've heard of others paying similar money so maybe Michelin are pushing them currently.

Shit Dude. Where did you get a deal like that? I just fitted 2 of the same and i paid way more than that for them. BUGGER! Mine was the big rear one too.:sick:
Actually they were Pilot Road 2's but all the same....

[NZsarge]

I thought so, but I've heard of others paying similar money so maybe Michelin are pushing them currently.


Indeed it is a very special price compared to what I paid and I thought what i paid wasn't toooo bad.. For the set I bought with a 190/50 rear it was $570 + fitting! That was the cheapest set of tyre I had bought in a long time so I thought I was doing alright.

[owner]

Name and shame the dealership I reckon
They fitted the wrong size tyre to your bike twice!!! WTF
I wouldn't be going back there
I bet it WASN'T Hampton honda or Pitlane

[shafty]

Dont go past Drury for bikes tyres............

lol yea it wasnt either of those. i went there cuz i work very close so was easy to drop off/pick up during work time. i will be going back for my next set at cost and free fitting but i doubt i will use them again for much else afta that

[ClutchITUP]

I dont think I would go back either
