Best for: It is built primarily for trail riding, technical enduro tracks, and low-speed off-road exploration rather than any kind of speed or highway work.
Built for: It has the character of a nimble, willing little enduro trail bike, eager to be flicked around obstacles but with only modest engine punch.
Not ideal for: It is not suited to riders wanting sustained highway speeds, long-distance touring comfort, or carrying a passenger any real distance.
