Who says performance and economy don't mix? The Buddy Black Jack 150 gives you arm-stretching, eyeball-popping acceleration and still sips fuel like a bird. But we didn't stop at the engine. The brake and suspension bits are name brand, top-shelf, race-tuned and beefed-up. The transmission is primed to launch you from stop lights. The Black Jack goes like heck, corners like a go kart, and stops on a dime.
