Has anyone fitted a 190/55 Rear Tyre To Improve Handling?

[Robbieben]

As per the title, on my ZZR 1400 I fitted a 190/55 rear tyre as opposed to the standard 190/50 and turn in on corners was improved and offered more sporty handling, has anyone done it with the GTR? or am I going to be the test pilot?

I think Debs did this, but I'm not certain

I run a 55 on pr4's and have done since acquiring the beast .ditto makes handling easier and more responsive..give it a try

I didn't as well, felt much better around corners and the same along the straights, improved turning in.

Thanks folks, that was my thinking. 190/55 it is then.

Yes, many over the channel are biking with that one

A word of caution - contact your insurance first and get them to verify its ok to do the change, they will take any route these days to avoid paying out in unfortunate circumstances if they have not been told of changes.

So if this is the case do we tell Mr Insurance man about the fender extender, Radiator guard, Top Sellerie seat, Hugger, top box, rear fender extender, grip puppies, laminar lip along with Uncle Tom cobbley and all?

I very much doubt it.

technically speaking yes you should   

Changing tyre sizes may be viewed as a structural alteration as opposed to the addition of an accessory   

[Robbieben]

a 190/55 Tyre actually has greater load carrying capacity so you could argue it was done on safety grounds

[PRD]

Be careful insurance wise if prob occurs they will use any excuse not to pay out. Also new bike under warranty if a prob occurs may say due to wrong size of tyre fitment. I would stay standard for mo. Not Worth risk for slight improvement in handling.

I know of several instances whereby people have lost their full claim because of none dis-closure of modifications. A tyre specification alteration would be considered a safety issue by altering the geometry thus the handling, albeit for the so called good. odds on the insurance would would see it as safety related.

Its the individuals call -- think on though can you afford to lose your bike and then afford to replace it like for like? in theory the new bike is double the purchase price ---   ask yourself is it worth it for a £150 tyre??

Better to be on the safe side

Have just renewed insurance on two of my bikes and one of the insurers said you was allowed up to 16 mods without having to tell them , don't know what they was , when I got some bst  carbon wheels for my ktm 990 I rang the insurers up and said am I covered , yes they said no extra charge but if the bike stole or crashed they will only payout on the standard wheels ,, ,,,,

A few years back 2007 I had a 7 week old bike written off in a head on crash (a woman hair dresser  didn't want to queue  )

I had had original parts fitted when new pannier frames top box heated grips alarm etc and the bill of sale stated this but insurance still only paid out for basic bike as said on here I had to sue for the balance by the way this was insured with bennetts never been with them since
