Standard Diablo's on Multi1000DS running 32 front 36 rear, excellent grip, excellent feel, they're responsive and supple, and I don't hang about on that bike. Lotsa people make the mistake of fitting Corsa's when the standard one gives all the grip that's needed and lasts so much longer (just ask Dom) , which ones have you been using?
I got to say that I didn't think the Corsa made bugger all difference to be honest. I'm going much quicker this season and (touch wood) I've not had any slides yet, not even at Brands in the rain.
I run diablo corsa front and a standard diablo rear!
They are great tyres wet or dry !
I had the same set up at llandow on friday and had the front tuck in the second session but that was running slightly off line passing someone on the out side and the rear was sliding alot but it was predictable every lap ! i ran 30 psi front and rear.
on the road i get around 2 rear 2 one front, rears will last around 1300-1500 miles.
Just been talking to one of the hartside guys I occasionally ride with - he's been complaining of the same experiences on his R1. It would seem that perhaps the sort of roads we ride on are the common factor.
I love em! I have always had them on the Multi since changing the original scorpion syncs. I get about 1600 miles from a rear and almost double from the front. I am pretty heavy though and the Multi gets some hammer. Also have them on the 996r (corsa front) but not paid any attention to the wear rate/mileage on that. No problems at all gripwise in the dry as bits of the multi touch down before you run out of grip. I find them excellent in wet/damp conditions as I ride the Multi all year round. I ride the same roads as you probably do (Hawes/Middleton/Alston etc).
I only started using them as a few years back a got a pair at a good price as I had always been a Bridgestone lover 010 56ss 56 etc. Have used em ever since. I dont doubt tyre technologies moved on and past me by but I really cant fault the Diablos. Maybe a little more mileage out of them would be nice.
