I've using Bridgestone T30 EVO's on my Triumph Tiger 1050, and before that, on my ST1300.
I was using Michelin Pilot Road 2 and 3's, but, while they get outstanding mileage (on my FZ1, I got 13,000 miles Front, 9000 miles Rear), they are bloody expensive!
The T30 EVO's are probably the least expensive premium brand Sport/Touring tires out there with pretty good performance.
I have had no problem with them in the rain or dry on the Tiger 1050.
While you may or may not get the miles of the Michelin's, they won't break the bank either, with a good price/performance balance.
