Re: Pirelli Diablo's
 

I think i've narrowed it down to Avon storms (£180 fitted) or Diablo Rosso's (£225) fitted. I want the best i can get but are the Rosso's £45 better than the storms???

Re: Pirelli Diablo's
 

Depends what you mean by better...

after deciphering the blurb on the Pirelli website it looks like the Rosso is a Sport tyre, this means it'll be soft, it'll heat quickly and give good grip when it is hot, but it wont last very long and its winter road / wet grip might be compromised.

Whereas the Storms are a Sport Touring tyre, which means that on a hot day or track they wont give as much grip as the Rosso, but on a cold winters day, or a p*ssing with rain day, they'll give more grip, and they'll probably last twice as long.

The Z6's are the Diablo Strada equivalent...

So IMHO you'd be better off with the storms, especially if you commute or are an all weather rider, add to that, that they are £45 cheaper, and they'll last longer, then thats what I'd plump for.

Put it this way I had Diablo Corsa III ( Sporty ) on my GSXR, I replaced them with Metzler Z6's ( Sport Touring ) and I cant tell the difference between the two, in fact I prefer how the bike feels on the Z6's...

Pure Sports tyres are always the best... depends on what you want to do with them. You're other problem is that tyres are subjective, I dont like Bridgestone BT014's but there are people out there that love em, so what I like you might not.

Only way you're going to find out is to buy a set and try them, TBH you cant buy a bad modern motorcycle tyre these days, so whatever you get you'll be OK with.
