Let me help ya, what part of "they are the manufacturer" are you having a problem with?..... If the bike is advertised as being supplied with that motor then that's what it will have to qualify with... Let me give you another example, the very popular Suzuki SV650 chassis is made at Suzuki but the motor is made in Korea by Hayosung... Suzuki advertises it as a Suzuki and that's how it is sold and classified... Now if you put a S&S motor in the Suzuki chassis then obviously it will have to Run in "A".... Another example the Aprilia RS250 uses a Suzuki's motor, that bike fits the "P", "A" and "M" classes.... It was a shame when we had to draw a line with Aaron's Buell but it all stemmed from when a guy showed up with a Kawi triple stuffed into a Honda chassis... At the time the motorcycle committee chair worked for Honda..... Its kinda like stuffing a Chevy motor into a 32 Ford roadster.... you just shouldn't do that..... As for this motor and chassis combination my vote is it would be legal into "M" due to its limited current production....
Norton, if you can make a street bike and show us advertising for the vehicle. Show that their is a legitimate intent for production.. show projections for production, parts streams, distribution streams, and the like,IE an intent for production, then you should submitt for approval.... Otherwise enter it in "A"
Tom will make the final call....
