I never had a problem with the oe Bridgestone tyres, enough grip to drag the footrests and main stand so OK for me. I changed to A40's but never liked them, to stiff a sidewall then moved to the Michelin pilot road range, 3's then 4's which I loved. I'm now on the road 5's but I won't use them again as the mileage is to poor. I could get 5k miles out of a road 3 or 4 but only 4k from a road 5, trail or standard. My search for the perfect tyre goes on and on!
