This is basically an SG-1000 version of the popular Sega arcade game Hang On, from earlier in the year. Has a decent re-arrangement of the arcade game's theme music. So you race against the clock to reach each checkpoint in each course.
While you appear to be racing against other motorbikes, there is no keeping track of your position. The other bikes are just for you to dodge. The sections of the course have different background - e.g green fields, yellow desert, blue water, mountains, rock mesas, skyscraper buildings.
