2004 Beta M4 Motard[edit | edit source]
Having a weight of only 133 kg, most people say the main feature of the M4 Motard is that it's extremely light for a bike in its category. Its 4 stroke, air cooled engine can make this bike get around with extreme agility, while not lacking in power, because the 26 horsepower released at 6600 rpm is strong enough. Taking advantage of its steel double cradle frame, it can prove to be very stable, having a wheelbase of 1410 mm.
