Kenichi Watanabe (Uchuu Fujima), fed up with high school, has one thing he can truly be passionate about: riding an NSR50 motorcycle. Kenichi, who has absolute confidence in his riding, gains help from Kanako Okazaki (Mayumi Kajiwara), to improve the machine's performance. Also, Kanako's ex-lover appears before him, and Kenichi sets out in two battles: riding and love.
