You'll get used to this small of change within 40-50 miles, if you don't do something silly. If anything, it will make steering feel a bit heavier - slightly taller tyre (due to the aspect ratio).



Really though, I'd say if you have to ask about this, you're not going to notice it as much as you're afraid you will.



Ride it, see how it feels. If it really bothers you that much, raise the forks 3-5mm in the triples. That should compensate for the slight ride-height change.

Sorry, I'm a bit fuzzy this morn: Yes, what they said about tyre.



Should have read it more than twice.

'cept for mebbe that "tighter turns" part.

OH! THANK GOD!

I don't think you will notice any real difference on your goof 2. Except any new tire should be nice compared to your shagged front. It seems to me most of the turning resistance that makes a difference comes at high speeds. i like the idea above of raising the forks a tad with a slightly taller tire, but you could probably also think about adding a click of preload to the shock. I believe dunlops stick good but are less stable at speed, in other words you can experience a little headshake on acceleration or a rapid pace. michelins seem to have less of that in my experience. i don't understand enough about profile and construction to know why this is. maybe its just me, but i doubt it. i use dunlops for the consistency mid corner.

Re: New bike tires... Handling change?
 
As AirHawk said, you can account for the taller tire by raising the forks in the triples. The most accurate way to determine the amount of difference is to measure the circumference of your current tire/wheel combo, divide by pi to get diameter, and divide the result by 2 to get the radius. Perform the same calculation on the new tire/wheel combo, and the difference between the two results is the amount you would need to raise the fork tubes in the triple clamps to have the same ride-height in front. All of this may be moot for you anyway. I would make the measurements in case, and just ride the bike after the change and see how it feels, gradually getting up to your usual pace. If it feels ok, ride it and don't worry about it. If it feels uncomfortable, make the adjustment to ride height. Don't forget to be easy on the new tires no matter what you decide, they can be slick!

Re: New bike tires... Handling change?
 
Don't worry about it, on a '93 CBR you won't even notice the difference. Unless you like spending money I'd quit buying Dunlop tires though, a little foresight and planning would have the correct tire lined up and waiting for you.

Hold on, I'm getting a rescue team together.



The good news is that I think we can reach you.



The bad news is the rescue team consists of Scott Glen, Chris O'Donnell, some English chap with a funny accent and myself.



We are going to take the most ridiculous and dangerous route and we need to wait until the English guy says something funny and falls off a cliff before we can get to you.



...I'm sitting here working and the crappy movie "Vertical Limit" is playing on FX right now. So bear with me.

He's got an internet connection and cant find a tire? The whole world is sold out?

The_AirHawk 03-17-2007 10:24 AM

Re: New bike tires... Handling change?
 
Nah, that's not possible. I'm checking right now, and there's lots of ..... SONOVA!!!



The whole World IS sold out!!

Re: New bike tires... Handling change?
 
What type of tires do Sonova make? Are they any good?

Re-badged ChenShen's.

The_AirHawk 03-17-2007 10:43 AM

Re: New bike tires... Handling change?
 
Oh, yeah - it's spelled "Sonova!..." - sorta like Buell does with the "Blast!".

The_AirHawk 03-17-2007 10:46 AM

Re: New bike tires... Handling change?
 
And right now, all they have is but two models of Track Tire: The "Ohshyte!" and the "AAAAAGH!".



I predict that once Privateers discover the brand, and how inexpensive they are; those two model names will be on the lips of Racers [i]everywhere...........

Could be worse. Could be Gigli.

Re: New bike tires... Handling change?
 
I'm not on a CBR, but I don't mix and match tires, especially with different profiles -- tried that with near fatal results -- so I'm a bit paranoid about it.



Check a different town... or the net (there are ton of tire dealers online) and have what you want delivered. Buy in pairs to make sure you're not stuck again.

Pirelli Diablo Strada. Stock sizes, they rock and last, win win.

Isn't that like Point Break with parachutes?

Seconded. Great tire.

No, It's like Cliff Hanger, except even dumber.



Vertical Limit is about mountain climbing...sort of.

Re: New bike tires... Handling change?
 
It was my understanding that he was getting two tires mounted - they just didn't have the stock 120/60/17 size for the front - rather a slightly-higher aspect ratio (120/70/17).

obandoj 03-17-2007 01:07 PM

Re: Diablo Strada +1
 
1st, 2nd and 3rd @ Daytona! I just got a set of Cinturatto's for my truck and they rock also, Pirelli is kicking but these days.

Re: New bike tires... Handling change?
 
AirHawk and all the others are right on: you'll only notice a difference over 60mph to the handling - you just need to use a bit more force on the bars because it increases the rake and trail.



You can reduce the rake and a tiny bit of the trail by raising the forks in the triple clamps (or to look at it the other way around, by dropping the triple clamps on the forks - 6-7mm should make enough difference). Personally, I wouldn't bother - I've been running 120/70s where OEM is 120/60 and I actually kind of prefer it.

Re: New bike tires... Handling change?
 
Well, got them installed (after reading the hilarity here), and they rock. Great handling and great feel, and I'm already getting used to the change in the feel (50 miles today alone). Thanks all!



as for getting other things: Everyone in town is sold out; everyone is getting their bikes into shape for the season

Dunlop was no more expensive than the Michelin... I'm confused, what do you mean?

The_AirHawk 03-18-2007 03:39 PM

Re: New bike tires... Handling change?
 
I think he's insinuating that the Dunlop's don't last very long. (which they don't - if you commute on a bike like I do - that's why got invented Tomahawks.........)

Another Satisfied MO Cusstomer (with emphasis on the "cussin' " part.....).

Lopoetve 03-18-2007 09:34 PM

Re: New bike tires... Handling change?
 
I didn't think they would, but that's ok. I expect 4k out of them and that's it :) My car tires only last 10-15k.
