Honda Motor has unveiled a new motorbike engine that it claims is 40% more efficient than those currently available
The 700cc, four-stroke, two-cylinder engine, a size popular in Europe, can do around 27 kilometres per litre (63 miles per gallon) of fuel, the company said on Monday, making it the best in the 500-750cc mid-range class.
The new engine will be installed in three models to be displayed at an international motorcycle exhibition in November in Milan.
Honda said the new engine would offer "outstanding fuel efficiency in the mid-class... for touring and urban riding".
