Triumph has confirmed during the Eicma motor show that the new bike will be unveiled in 2015. Probably it will be powered by the single cylinder engine distinguished at the spy photos of the 250 c.c. naked bike, shown here. 

This class becomes very competitive in the last years with single or two - cylinder engines, displacements between 200 and 390 c.c. and faired or naked bikes. Concerning performance the number of cylinders and the engine capacity is certainly a plus. However this is not the only decisive factor on every market.
