Reverse Engineering Options

Thanks for the input, it looks like I will be working from 2d drawings for the time being, but I will also look into scanner rental. I am planning to develop fairings, rear seat cowls, protective guards for stator covers, crankcase covers, etc. So having the mounting points for the bike itself like you were saying is a good foundation to design the parts.
As far as the direction I would like to take the business, I don’t want to just make aftermarket plastics with different paint schemes like all the other companies, I want to change the overall look of the bike. For example , if you look at sport bikes on the grid of a moto GP race, to the untrained eye all the brand look virtually identical vs the starting grid from an IMSA auto race where each brand (Ferrari, Lamborghini, Porsche, etc.) has a very distinct, unique look to it. Most production sport bikes look very similar and IMO have not produced many original designs over the last 10 years or so (with the exception of Ducati’s bikes, also the new R6, R1, H2R, and some of the other less known brands), but the point is that I feel like there is a lot of untapped potential as far as creative designs for sport bike parts go.
