Sometimes, it takes a problem to invent a solution. Example: Wanting to engage young people in motorcycling resulted in Yamaha creating the YZF-R3, a neat little sportbike that, although light in performance, gives away nothing in appearance. Indeed, the R3 looks reasonably like a scale model of the mighty YZF-R1. The engine is a tidy 321cc parallel twin, giving it a 28 percent displacement edge on some competitors’ 298cc engines. It even has dual overhead camshafts, forged pistons, liquid-cooling, and electronic fuel injection (EFI) like its big brothers, the R1 and YZF-R6.
