I never cared for two strokes.... Til I got my KTM 300 a few years back. I ride at Stonyford in northern California and its perfect for the tight woods and nasty climbs. I will begrudgingly take a buddies 450 so they can try the mine. It's fun but doesn't rip like 300cc's of angry two stroke.
That's why some call it a 3-Stroke.
Here's decent climb, though camera perspective doesn't accurately portray the incline, the audio does reflect how stong and flexible the 300 motor is.
