Geometry
Fun, sure-footed geometry: The soul of any bike is the geometry. Through years of experience of riding the backroads of Asia, we have tuned the geometry to represent what an all round adventure bike should feel like. 430mm of chainstay length makes sure that the rear end fits big volume tires and still remains snappy. The relatively steep seat angle ensures your weight is optimally centered between the two wheels and the lowered BB height makes you feel like you're sitting IN the bike rather than ON it. Along with a slackened out head angle, the A21 will smooth out the roughest roads you can throw at it.
