Here's the skinny for BSB.
1) Full FIM World SBK Spec Class as the "Premier" class
2) New "EVO" Class with SBK Spec rolling chassis, and essentially very regulated "stock" motors with a spec ECU eliminating traction control, launch control, etc.
The factory boys still have a playground, and those who want to run a liter bike can do so, at a projected 200,000 GBP annual operating cost savings.
Win, Win.
