Piaggio MP3
The Piaggio MP3 is a tilting three-wheeled scooter from the Italian manufacturer Piaggio. It was first brought to market in 2006.
Two wheels are in the front and one in the rear part of the scooter.
Variants
125cc, 250cc and 500cc versions are available. Piaggio is producing a similar 500cc three-wheeled scooter under the sporty Gilera brand, called the Fuoco 500.[1]
Suspension mechanism
Because of its unique three-wheel mechanism, it can be brought to a stop and parked like a car, without concern for a traditional kickstand or centre stand. The front suspension is similar to the single-sided trailing arm of Vespa style suspensions, linked by an alloy parallelogram and a central steering arm. Care must be taken[citation needed] when increasing the throttle from a stop since the front suspension locking device disengages after the engine is brought to revolutions above idle. When moving at slow speeds or stopped, the rider must maintain balance through forward motion or with feet on the ground. The front suspension locks or unlocks with the flick of a switch, located just below the throttle on the right handlebar. The suspension lock can only be activated manually, and only at low speeds or at a stop. A parking brake is used in conjunction with the locking mechanism to park the bike. A traditional center stand is also provided, proving useful in situations where the suspension is unable to be locked, i.e. no battery to power it.
Riding experience
The unique feature about this three wheel vehicle is that it has all the riding traits and handling characteristics of a motorcycle with the added advantage of a third "footprint" that dramatically enhances stability and stopping distance. It is different than a standard three wheel "trike," which is only similar to a motorcycle in terms of looks and mechanics. With a trike the geometry of the steering and the consequential inability to lean considerably alters the steering technique and the cornering ability. Conversely, the Piaggio MP3 advertises a 40 degree lean angle; greater than most bikes on the street today. Countersteering techniques used in normal motorcycle riding must be employed to fully utilize and control the MP3.
Potholes, road debris, pavement cracks and even road edge "traps" are substantially reduced threats because the third wheel enhances safety through stability. Even problems with inappropriate braking techniques, normally relegated to two wheel motorcycles, are forgiven because of the weight distribution, low center of gravity and extra balance derived from a third wheel. Having a third wheel which adds the third disc brake gives the rider 50% more tire on the road for traction and 50% more braking.
