50 or 55 profile rear tyre

Why do some riders change from a 190/50/17 rear tyre to a 190/55/17.
I obviously realise it would make the bike longer geared slightly.
I bought a 2010 cbr1000rr earlier this year and it has a Avon av80 190/55/17 but I've noticed the original spec is a 50 profile, the tyre hasnt last very long at all and is down to the markers so I'm going to need one soon.
I'm just wondering whether to put a 50 or a 55 profile back on

Thanks

 

Stick with a 55, it's not for the gearing, it makes the bike turn in quicker as the tyre is taller. It lifts the back end approx 8.5mm so is equivalent to dropping the forks thru the yokes without sacrificing ground clearance. The speedo is usually out by a certain percentage and I have read that this puts it back to a true reading. Not sure how true that is but I suspect it is so.

 

55 gives a quicker turn into corners.

 

Had a 50.......went to 55......prefer the 55. That's all I can tell you.

 

55

 

Thanks guys, i will stick with the 55 then.

 

55

 

Only issue on a Blade can be that the tyre may rub the hugger. Mine doesn't and as you are removing a 55 you should be ok.

 

Yeah it should be ok as there is good clearance now, the other thing to think about is I've just fitted a taylormade exhaust that is quite close to the tyre, I suppose it's only 8.5mm closer than normal.
Thanks for your help

 

Had 50... Tried 55 and went back to 50 ... The blade doesn't need faster steering.

 

I love the quicker steering on the Blade. Didn't you drop your forks thru the yoke?

 

I love the 55 profile, my mate on his R1 runs a 60,

 

55 on mine. I had to raise the hugger sligthly.

 

I'd say 50 for the road and 55 for track.

Combination of what you require on track and road.

 

you could try 200x55 or 200x60
but yeah I would say 55 feels better on road and track, so keep with that mate

 

Exactly this ...

 

Thanks for all your comments, I've only had the bike a few months and just getting used to it so I think I'm probably best off keeping it as I'm used to.
Thanks again guys

 

If anyone on a Blade prefers the 50 series tyre then maybe U shouda bought a VFR instead!

 

Tell that to Mr Honda who still supplies brand new blades with 50 series rear Tyres ...

 

Yeah right!

They've been told that their ABS is WANK too, but do they listen?
