Price check on a pair of GPR-70s

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

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

Set the pressure correctly

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

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

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?????

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