2004 | Birdie 50 (4-Stroke)
Lightweight, reassuringly stable, and easy-to-handle commercial bike

Featuring a brand new chassis and engine, this full model change of the Birdie 50 (4-Stroke) was designed with an emphasis on easy handling, riding stability when loaded, and durability. The 14-inch tires and newly designed pipe frame help to realize a low seat height of 705 mm, and a low step-through height of 480 mm makes it easier for the rider to mount and dismount from the seat. The front bottom-link suspension of the previous model was changed to a telescopic suspension, helping the rider to negotiate uneven road surfaces and obstacles more stably, even at an angle. The dry weight of the Birdie 50 (4-Stroke) is only 69 kg, the lightest in the 50 cm³ commercial bike class.
