As motorcyclists, we know there is always more than one way to get to a destination. That same concept applies to engine design. In the growing mid-size four-stroke off-road market, the big players are Beta, Husqvarna and KTM, and each took a different path to get to its end displacement. Husky started with a 250cc engine and used old-fashioned hot-rodding techniques to grow it to 310cc. KTM felt the class was worth a little more investment, so designed a 350cc engine from scratch. Beta based the 350 RR on the 400 to 498cc engines used in all of its four-stroke off-road models, downsized to 349cc. Oddly, the end result is within a tenth of a millimeter of the KTM’s bore and stroke.
