The KTM 350 SX-F has been a popular choice among the Austrian motorcycle manufacturer’s dirt-riding clientele since the midsize motocrosser was introduced in 2011. The electric-start engine has respectable bottom-end, good midrange, and seemingly never-ending top-end. No internal engine changes were made to 350 SX-F for 2020, but the new vented airbox cover is a simple and effective addition, and it is included with the purchase of the bike.

“It’s like going from pump gas to high-end race fuel,” test rider Allan Brown said after installing the optional cover. “It adds power across the entire rpm range and makes the engine feel like it wants to rev to the moon. I tried to find the rev limiter a few times but, assuming I came out of most corners in the correct gear, it was almost impossible to reach.”

What’s more, revised settings for the WP Xact air fork and shock have resulted in increased plushness at both ends of the motorcycle. So if you’re an all-round rider or racer who likes to dabble here and there—motocross, off-road, and trails—seriously consider the 350 SX-F when making your next dirt-bike buying decision.
