Re: The definitive idea......
I think you are on to the right direction but wrong engine configuration. I think the inline 4 will screw up the Buell chasis. The Buell chasis and looks are fantastic. Too me the Firebolt still looks like a new design to me. Even though I put down twins all the time, I think Aprilia, Ducati, and KTM have shown that modern liquid cooled V-Twins can be terrific sport bikes. Did you check out the Aprilia story on the V-4? If you click on that link you will see their new V-Twin bikes as well. Awesome.
