The Yamaha Libero G5 is a 106 cc, single-cylinder four-stroke motorcycle from India Yamaha Motor. Its predecessor was known as just Yamaha Libero. Unlike Libero G5, Libero had tachometer and round headlights but lacked fuel gauge. However, Libero G5 came with a sporty headlight and fuel gauge, but lacked the tachometer. A new set of air scoops with a honeycomb grille do dual duty; directing airflow over the engine block and also neatly covering the gap between the engine and the fuel tank. The Libero G5’s frame continues to be the tubular dual-cradle type.
Yamaha has introduced a compulsive pressure wet sump lubrication system in the 106 cc engine of the Libero G5. This new system works on a constant pressure build-up that is generated by the engine itself thus enables the engine oil/ lubricant to flow evenly over all the engine components, unlike conventional lubrication that works more on gravitational forces thus may not perform as effectively.
Yamaha Libero G5 is particularly made for Indian market. However, Yamaha Libero G5 is also popular in Bangladesh. Ground clearance is a comfortable 173 mm, enabling the bike to take on speed-breakers and potholes with greater confidence.
In 2007 Yamaha released an upgraded Libero G5 model with alloy wheels and electric starter. Like most Indian motorcycles, this bike comes with a saree guard to increase the safety of female pillion riders. A less sporty-looking version (with same engine) of this bike is marketed as Yamaha Alba. A bigger cousin of this bike with 125 cc engine is Yamaha Gladiator. Some similar/competitor bikes are Hero Honda Splendor, Bajaj Platina, Bajaj CT 100. Production of Yamaha Libero G5 ended in 2010.
