should have had pirreli diablos fitted mate I run them and cannot fault them. I use to run bridgestone but I think the diablos are beter
Diablos are much better during the colder months as they heat up quicker to give the grip, but in the summer months, BT014's can take advantage of the warm weather to give you even more grip, and they still heat up prettyfast, just not as fast as Diablos...
If your only gonna change your tyres once a yr, Diablos are the ones ya want, but if you do lots of miles like me, then try some BT014's when the suns out, you will be very much suprised at the difference
PS: I use BT010's on my 400 all yr round, fantastic tyres, but they don't work that well on larger machines 750cc and over!
