In the dirtbike world, however, there has been a bit of a backlash lately, as an increasing number of riders have been returning to two-strokes. Why? Lighter weight and snappier throttle response, for starters, but perhaps more importantly, reduced cost of ownership. Not only are two-strokes less expensive to manufacturer and thus purchase due to their having fewer moving parts, they’re also cheaper to maintain—there’s no labor-intensive valve train to look after, and a new top end costs just a few hundred dollars compared to a few thousand. Proof of this trend can be seen in the success of KTM’s 300 XC-W enduro, which after being fitted with an electric starter became one of the Austrian firm’s best-selling models.
