ECOLOGIC GUIDE
•Every vehicle powered by an internal combustion engine produces an amount of
noise (noise pollution) and gases (air pollution) which varies with the riding style.
•The abatement of noise and air pollution levels is the duty of everybody. Avoid
full-throttle starts, sudden acceleration and abrupt braking. This will reduce noise
emission as well as the wear and tear of the tyres and mechanical parts, and will
also allow a considerable reduction in fuel consumption.
