Tests carried out by Marco Melandri (a new hire by BMW for the 2012 series) and Leon Haslam at Portimao earlier this week provided information about the 2012 BMW S1000RR superbike. Although we expect a more detailed announcement from BMW tomorrow, it has been revealed during the superbike tests that the 2012 bike will have a revised steering geometry, as well as new faring profile for improved aerodynamics. Engine changes are also apparently part of the package, providing improved midrange over the current model.
Basically, BMW has homologated changes to improve its superbike, presumably as both a race machine and as a street machine. We should have an official announcement from BMW tomorrow.
