New BT-002s for road and track.
The local paper's bike journalist has been at a Bridgestone demonstration at Ascari where Jeremy McWilliams has been demonstarting the circuit for the journalists and apparently he genuinely speaks highly of the tyres and says he failed to get the Racing Street tyres to slide or move.
Presumably other mags are now reporting on the
Bridgestone Racing Street BT-002 tyres.
These are adapted from the DOT race-only BT-002 tyres.
The front has a dual compound.

"Race-bred performance for street superbikes
Bridgestone’s Battlax BT-002 Racing Street series is a new-generation of MotoGP-inspired hypersport tyres designed to provide outstanding street and track day performance for high-powered bikes of 600 cc and above.
Derived from the BT-002 homologated full-race range, the Z-rated Racing Street front/rear pairing delivers outstanding contact feel and precise cornering ability. Its main adaptation for practical road use lies in the selection of tread compounds that combine long-life durability with sure-footed response under wide-ranging surface and weather conditions.
Dual-tread construction of the front tyre, with a medium compound in the centre and a soft grade in the shoulder area provides high grip while retaining light steering. ?A steel Mono Spiral Belt (MSB) comprising a continuous single cord wrapped around the circumference of the tyre in order to eliminate seams, joints and the overlapping of belts, reduces weight compared with conventional multi-cross belt construction. It nevertheless provides greater stability by minimising internal heat generation.
...?At the rear, a silica-rich compound again enhances grip. The profile and tread pattern are adopted directly from the BT-002 race tyre. A large, flat crown radius brings smooth and linear turn-in characteristics, while the tread ensures straight-line drive stability, with optimal distribution of the grooves aiding middle to large camber cornering.
The Battlax BT-002 Racing Street series is produced in three sizes: 120/70ZR17 (58W) TL (front), 180/55ZR17 (73W) TL and 190/50ZR17 (73W) TL (rear).
