These new Bridgestones are an all round sports tyre so should have a better grip than the normal BT-016, so if you are going to use them on the track then these are just fine.
If you are looking for more of a sports/touring tyre then stick with the BT-023, for street use only, then look at the BT-003.
I think that the BT 016's were an OE fitment on the LO.
my K8 750 was fitted with them when I bought it new, the OE fitment is a different tyre to what you buy over the counter.
Suzuki fitted a single compound front tyre & a dual compound rear as OE,
The over the counter tyre is a dual compound front & a three compound rear, that may explain the mixed reviews,
my OE fitment lasted 2700 miles, the second set I purchased did 4000 as a pair.
I know this is an old post but i highly recommend these bridgestone tyres, especially the over the counter bt016 PRO version(as thats all i have used), more than enough grip for fast road riding and i done a trackday at cadwell park on my k6 600 and they were fantastic, they heat up very quick. Never tried them in the wet but apparently they are very good then also. I think intobikes.co.uk have them on special offer again at just under £170 a pair with a 180 rear. Definately the best sports tyres for that money!
