”Lightweight and compact mini bike popular with female riders ” says Suzuki about the Youdy Mini, introduced in in Japan as 1978 year's model. Designed for smaller riders to mount with ease, the Youdy Mini is both easy to handle and ride. It had a dry weight of only 44 kg (97 lbs) and its bicycle-style brakes and automatic transmission made it a great little bike for beginners. With the popular Japanese singer Masako Mori acting as its poster person in advertisements, this model became popular among a wide variety of riders, particularly women.

The Youdy Mini features a lightweight and compact body with a 50 cm³ air-cooled 2-stroke single-cylinder engine. A rider-friendly design was created by adopting bicycle-style brakes and an automatic transmission that eliminates the need for shifting and allows the bike to be ridden simply using the throttle alone.
