According to UK-based Raptors & Rocket's sources, the Bandit 650/1200 will be missing from the '07 lineup worldwide due to inability to meet Euro III emission standards. The GSR600 will be joined by one or more larger stablemates to carry the Suzuki badge in the sporting standard line. Still not clear if the 600's bigger brother will sport a GSXR1000 or a Hayabusa based engine. What's new though is rumor of a V-twin variant sporting the big twin from the M109... and the possibility the B12 engine, with EFI and updated catalyzed exhaust might see a GSR format.
Concept of what a GSR1000 might look like:
Concept of what a GSR1800 might look like:
Concept of what a B12 powered GSR1200 might look like:
I'd be really surprised if a B12 powered version is made since the current GSR600 is already putting out power figures close to the B12.
