64.5kg Ossa TR280i is world's lightest trial bike
22 July 2010 15:32
Reborn Spanish brand Ossa has come back with a bang – a sleek-looking new trials machine it says is the lightest in the world.
The 64.5kg bike is the first new Ossa in 25 years and features a 272cc two-stroke single-cylinder engine. Production begins in September, with the entire 1250-bike initial run sold into dealers around the world.
A second batch of 2500 will follow next year, by which time a newly-developed upside-down fork will be an option.
