Ridden under harsh conditions throughout the year, the Birdie 90 (4-Stroke) is a commercial bike designed for delivery, catering services, and other applications that demand the highest durability. These requirements are satisfied by a quiet and superbly durable 90 cm³ 4-stroke air-cooled 1-cylinder engine that is ideally suited for early morning delivery routes. The Birdie 90 (4-Stroke) features cast aluminum wheels and tubeless tires capable of securely supporting heavy loads, as well as a tandem pillion seat as standard equipment. Other features include a fuel tank that can be locked using a key to discourage pranks and gasoline theft, as well as a front brake lock for greater stability when parking.
