The mountaineer Appa Sherpa was introduced as the brand ambassador for Yamaha Libero motorcycles this week. Yamaha dubbed Sherpa a 'Mileage' mountaineer for his extraordinary feat of summitting Mt Everest a record 13 times, to draw parallels with the 'Mileage' bike that is capable of stretching one litre of fuel over 85 Himalayan km. The 4 stroke, 106cc, advance engine bike is available in four colours at Morang Auto works, the sole distributor for the company.
