There are only 2 tyres in the correct size; Metzler and Avon Cobra, both 240/50x16. Of these, I found the Avon far superior in dry conditions and certainly no worse than Metz in the wet. I got 50% more mileage from the Avon too. They cost about the same.
The Bridgestone is 240/55x16. Same width (although it is actually physically wider) but higher profile. This gives you very slightly taller gearing, which is fine on a Rocket because the torque handles it easily. By raising the back a little it makes steering more responsive and I find it puts me better in the power band coming out of corners, but that will depend a little on how you ride. It is more cushioned so gives a better ride and just plain looks better. It also has the effect of correcting your speedo. Much better in all conditions than both the others, costs less and gives me double the mileage of the Metz.
A no brainier if ever there was one.
I partner it with an Avon Cobra on the front. Perfect!
