True true true.
Bimota built the V-due, a direct injection 2s that would have met (and did) epa and carb regs. it just bankrupted the company.....

as epa regs dissuaded the japanese co's and turned them away from 2s to 4s for ease of compliance, it forced them to look to 4s for racing also as research (race on Sunday, sell on Monday) dollars are always scarce...........
