A sensible sports/tourer and even a stylish commuter.
Classic styling and Kawaski colour schemes. Just like the bigger GPX bikes (only smaller so if you're tall or big you'll look like you're riding a Shetland pony). Not very heavy so watch those cross-breezes on the freeway (i.e. wind shears). GPX250, ZZR250, GPZ250R all use variants of a water cooled DOHC 16 valve parallel twin. Tough but watch out for thrashed engines. Cinder-switch is occasionally burnt out so check it when buying.
