New 2011 Aprilia 450 MXV : Reviews and Specification

Aprilia.com All design solutions without compromising on MXV 450 have been dictated by the need to achieve the highest possible level of performance while extending the range of bicycle use.The under seat exhaust, for example, has a completely new way for motocross best performance with more torque at lower rpm.valve based on a single camshaft and four valves per cylinder titanium gives the best possible compromise between compactness, light weight and performance.Thank you to the advanced technology of the 45.2 engine is extremely civilized and silent operation, even in this motocross version, and responds easily to the FIM rules for noise emissions (94 dB threshold).The 450 MXV allows easy access for maintenance magnificently (plugs, oil filter, air filter), and has long service intervals well above average.The engine lubrication system with dry sump oil tank integrated into the crankcase. Removal of oil tank and its external connection pipes has led to a further reduction in weight.The starter has been eliminated for the same reason. The start is the kickoff for reducing weight.The salient specifications of the engine 45.2, the new MXV:electronic fuel injection.dry sump lubrication with oil reservoir integrated into the crankcase. Separate lubricating gearbox and engine to keep the oil more effective.single overhead cam titanium valves.piece crankshaft.Cylinders integrated in crankcase, wet protects.Choice of "Big Bang" and "settings ignition Screamer"."Hard / soft" mappings selectable from the handlebars.stepper motor idling control electronics.Maximum engine speed 12,500 rpm.

CHASSIS: more light than everThe frame dimensions of the perimeter have been optimized for use motocross, and the whole framework has been developed to complement the engine. Its design is unique among senior motocross. A lattice steel tube is equipped with interference aluminum side plates pressed to form a unique structure. The engine is also part of the chassis, acting as a bearing element and contributing to exceptional overall rigidity.Special care has been taken over the distribution of weight. The weight has been centralized to the extent possible to improve agility in all conditions.Weight reduction (one of the most important aspects of any motocross) heart was in the design of each part of the MXV, disc brakes to the frame.The swingarm was designed for maximum lightness and elasticity and incorporates hydroformed members. The system of rising rate link is cushioned by a Sachs shock absorber adjustable race with two damping settings for high and low speed riding.The advantage Marzocchi 50 mm stanchions and has also calibrated for motocross. The fork is fully adjustable, so you can set up your own suspension action exactly as you want.The fuel tank has been redesigned to keep the center of gravity of the motorcycle as close as possible to the physical center of the machine. Attention was also given to the elimination of projections to reduce the width and improve ergonomics.The centralization of weight also influenced the design of the filter housing. The filter is now located at the front of the bike, leaving the fuel tank to go up more space on the rear shock.The filter housing also holds the throttle body and easy filter change.The ECU and all electrical system components are kept secure inside the filter housing.The exhaust system, mufflers under the seat and twin tail pipes are made entirely of titanium (pipes and muffler).The electrical system is minimal without battery, and fully integrated within the filter housing. Engine and electrical system are therefore a single block.The two tones enhanced security helps the rider hold office at any time.BRAKESThe unprecedented technology and performance of the chassis are supported by a fantastic braking system. The MXV is equipped with Nissin floating callipers and super-lightweight wavy discs (270 mm front) for braking unparalleled, even in the toughest conditions.A disk of 240 mm in the rear with piston caliper Nissin simple offering the perfect balance between stopping power and ease of control
