Suzuki GN series

The Suzuki GN series is a series of standard motorcycles built by Suzuki since the early 1980s, including the GN50E, GN125, GN250, GN400 and GN600. All featured air-cooled SOHC single-cylinder engines with chain drive and were designed to be easy to ride by beginners. Early GN250s had a front drum brake that was touchy in cold or wet weather, replaced by a disc after one year. The GN400 was based on the SP400 Enduro and was also sold as the GN400X with spoke wheels, and the GN600T Road Sports was based on the Suzuki DR600. The TU250X descends from the Volty and Grasstracker models, which were heavily based on the GN250, and the 2007 GZ250 shares the GN250's basic powertrain with a cruiser theme.
