Best for: Built purely for motocross track and off-road racing, with a small two-stroke engine and race-tuned suspension rather than any road-going intent.
Built for: It's a peppy, high-revving two-stroke that rewards aggressive throttle and clutch use with sharp, flickable handling on rough terrain.
Not ideal for: This bike is not suitable for road use, touring, commuting, or carrying a passenger, and it lacks the size and power for taller or heavier adult riders.

Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
