EICMA 2005 - NEW 50cc MINIMOTARD



01.12.05 - Little go-kart tracks are its familiar ground. It is extremely handy, has a perfect weight distribution. It is equipped with a liquid cooled high performing engine with direct crankcase reed valve induction. The 19mm carburettor optimises the power output at the best. The 50 cc Polini Minimotard is both for adults and for the young too because it can be ridden at every age. Driving a motard is really a unique experience. It is a challenge at the latest curve among riders with outdistances at the limit, counter steering bikes, spectaculars skids before straight and folding at the limits. The new Polini Minimotard offers all these sensations; it is a ageless vehicle for the amusement of adults and young riders on go-kart tracks. Its technical solutions are new and innovative. The new exhaust system has a chrome-plated expansion and the silencer made of light-alloy. Tyres have a tread pattern special to be used on the track. Suspensions are rigid in order to better conform to the drive on track. Fork and rear single shock absorber are fixed. The bike is supplied with a spring kit for front fork. Rear shock absorber is available as optional accessory because it is not specific for the way of riding to which Polini Minimotard is intended for. Its style is modern, young, aggressive. That's why the new Polini Minimotard doesn't only mean power, but also versatility, safety and amusement.

NEW FRAME WITH STRONG AND STEADILY PERSONALITY DRIVING POSITION AND BALANCING ARE SUPER
The frame of the Polini Minimotard distinguishes itself for the design of the primary structure, single beam split before the cylinder. It is realised with steel tubes of very first quality and its features specially increase the resistance to torsional stress and the elasticity. The tubes of the frame are of different diameters, a technical solution that gives a better resistance and strength. The swing-arm, realised in steel too, has got two arms of trapezoidal section for a better resistance to every stress. These features give important improvements: easy of handling, you are more equilibrated and faster in taking a curve, steadier, more precision in the radius curve with good sliding and a perfect balance. The rear single-shock-absorber suspension is fixed. The Paioli tele-hydraulic front fork is now stiff and no spring is assembled. Legs have been reinforced. The steering damper is assembled on bearings with cylindrical rolls, providing a better stability on hilly ground. The handle-bar is realised in light alloy and has a reinforce-stud, like the one you can find on high-displacement Motard, covered with foamed material, for a high shock absorption. The 150 mm. disc brakes have mechanic control. The light alloy wheel hub are assembled on steel rims. The very smart graphics are studied down to the smallest details. Realised in anti-shock plastic material, as the other superstructures, the fuel tank has 4 l capacity.

ENGINE: THE EVOLUTION OF A FAMOUS SPECIE
The crankcase is in die-cast light alloy. The bike is air cooled. The cylinder is characterised by a graphitic and lamellar cast iron melting with high mechanical resistance. This particular melding ensures a better smoothness of the piston and makes the cylinder more wear proof. It has five transfer ports. The bore and the stroke are of 40X39.3 mm. The piston, gravity die-cast has two special S10 cast iron piston rings. The lamellar admission is direct in the crankcase and commands a valve with 2 opposed carbon fibre reeds. The pump of the liquid cooling system is placed on the rear part of the crankcase. The starter bracket is on the right side. The starter is electronic CDI. The Dell'Orto carburetor is a PHBG 21mm. The secondary chain transmission has a new tuned pin placed on the left side of the crankcase. The centrifuge clutch with primary transmission is one-stroke type.

DIMENSIONS AND WEIGHT
The new Polini Minimotard have 10'' front and rear wheels, provided with special tires for Motard races. The bike empty weight starts from about 40 kg.
