Must be the testing they do for the bikes on English roads.
The test riders have significant imput into the tyre choice etc for each model of bike.
They puts thousands of miles of testing in and are all experienced riders.
For them to spec Bridgstones, they must've been the best for the bikes while testing.
I run Bridgestone Xedra G546 (rear) and Bridgestone Battlax BT45F (front) and they're great for me.
