Price check on a pair of GPR-70s

[Coyote]

Simple question, how much is a set of Dunlop GPR-70s for my CBR?

[FROSTY]

wot size are ya wheels??--what tyre sizes ??
I have a 160 and a 120 you could have pretty cheap for the pair -second hand of course

[John]

alot. around 470$ IIRC

Darn. 110/70 front, 140/60 rear

alot. around 470$ IIRC
Double Darn. I've got a bit of saving to do

Shit frosty i have a 160 on my cbr600 i don't think it'll fit on the 250. But yeh you're looking at about $500 a pair fitted.

You may find a slightly better tire on the 250 is the dragons (not the corsas). They handle pretty similar to the dunlops, but dont go cold so suddenly (my only complaint with the dunlops). But they are both roughly about $250 each. The other thing I found that the dragons handled precision throttle control with a little more predicability (but thats personal choice). I enjoyed both sets of tires :)

What brand are they?

[TwoSeven]

pirelli :)

Where can you get pirelli dragon 140s from? (I think thats the 250rr rear tyre size) I love them but haven't been able to find a place that sells them anymore

[TwoSeven]

From memory I think you run a 150 on the rear in pirelli. Cycletreads will have them, but you may have to order them in (doubt they'd have that in stock).

Yep you can but if you have any sense you wouldn't. Screws up the handling of them and makes them alot harder to turn in etc. Specially if you are using them for racing. Stick to the GPR70's and they will last you a decent amount of time. Only better alternate is some slicks.

had Dragons (MTR22's???) on my 400... found them to be a shit tyre... spin up way too much and couldnt get the power down... Go for the GPR70's full stop... superior tyre and will stick like shit to a blanket on a CBR250...

Streetstock rules prohibit slicks, which is a shame

Looks like I'll go for the GPR-70s, once my 80 is sold

It would only screw up the handling because you probably didnt know how to adjust the bike to suit the different type of tire you are using :)

Set the pressure correctly :)

What's the advantage of setting it up to suit a 150 rear?

I did, and it didnt like it no matter what pressure...

Ok, in my opinion the difference between a pirelli and a dunlop in really basic terms is that for former will cope with being put on the same lean angle time and time again, so it favours a really smooth throttle style with minimum brake use. A dunlop because of its construction is the opposite, it is unpredictable in its movement and favours a heavier throttle use to deliberately move the tire around (this rule i've found to be slightly different on the newer silicon tires)

This is the basics between both companies manufacturing style for the two types of tire mentioned.

Now a 150/60 has a 90mm height and a 140/70 has 98mm height. So the pirelli lowers the rear by 8mm. I think both fronts are the same. (note: these numbers are ball parks, use a tape measure because your rim size and inflation pressure make a difference).

The effect of putting the pirelli on slows the steering slightly and also favours its style of precision throttle movement - which happens to be (in my opinion) ideal for the cibby. It also moves the c.g. back and forces you to adjust your body position (you can counter by dropping the front slightly).

I found the dunlop favored the quick hard turn in and aggressive moves on the throttle, but for my style of riding I kept losing control on some corners because of its unpredicability and the fact that I'm fairly precise on the throttle (I set it and hold it rather than move it all around as I am not a devotee of the ride by feel method).

I also found that going thru patches of dampness caused the dunlops tires to suddenly slide (which I eventually got use to and had some fun with) - I found the pirelli's to hold their heat more (especially when stopped at the lights).

I think each to their own really. Try the dunlops and see what you think - I had a set on up til I sold the bike - they are good tires and I think the most easier to get. (I am biased because i've used michelin/pirelli for nearly 20 years, hence I favour that style).

blah blah blah

Now a 150/60 has a 90mm height and a 170/60 has 102mm height. So the pirelli lowers the rear by 12mm. I think both fronts are the same. (note: these numbers are ball parks, use a tape measure because your rim size and inflation pressure make a difference).

blah blah blah


A 170/60??? on a CBR250????? :oi-grr:

[TwoSeven]

oops. fixed now. Its was the 600 I put the 170 on, the 150 went on the 250. :)
