2004 Aprilia MX 125

Aprilia MX 125

Significant work has been done in terms of aesthetics by the APRILIA designers, who have especially created a brand-new front section for the MX 125, made up of the new generation mudguard, front fairing and transparent headlight; the ducts, the side panels, the plate holder and the smaller and better connected rear headlight, the aluminium handlebars and the modern digital dashboard.

The MX 125 is a true supermotard, as demonstrated by its trim and the riding position; the saddle, the footrests (widened for better grip), the suspension, the brakes and the 17" spoke wheels make the MX 125 a winning supermotard.

The braking system on the APRILIA Supermotard is extremely powerful for a 125 cc bike: a 320 mm front disk with floating two-pot calliper, and a 220 mm rear disk, also with floating calliper. The 40 mm upside-down telescopic fork features a wheel travel of 260 mm. The rear end features an adjustable single hydraulic shock absorber with piggy back (able to guarantee uniform operation); the wheel travel is 280 mm.

The main technical development in the creation of the Supermotard involves the wheels. In the case of the MX 125, the new components include aluminium spoke rims, 3.00" x 17 at the front and 4.25 x 17 at the rear. As a consequence, the tyres chosen are the large 110/70-17" and 150/60-17" road wheels, on the front and rear respectively.

The MX 125 engine is well known to 125 cc bike enthusiasts and experts, the superlative APRILIA liquid cooled engine, with balancing countershaft. The cylinder has a nickel and silicon carbide coating, which can deliver high power while ensuring long piston life. The exhaust is made from stainless steel, with built-in catalytic converter. An "absorption" type stainless steel silencer is used, for better noise abatement. All naturally in compliance with the upcoming Euro 2 emission standards. Lubrication is managed separately using a mixer.

No corners have been cut in terms of the dashboard, confirming the desire to create a versatile and practical bike for everyday use: the MX 125 digital dash features a new, innovative design, with all the functions required for the sporting use of the bike, and not only. Instant speed, maximum speed (recorded), average speed, odometer, trip time, lap time, clock, flat battery signal, oil in the mixer in reserve warning, service request signal. All this plus the 5 lights for the blinkers, neutral gear, low beam, high beam and the engine temperature/oil level.

The APRILIA MX 125 is dedicated to today's sixteen year olds, for whom the scooter is no longer exciting, lovers of the motorbike and the sporting ride, but who find the exciting 125 sporting road bikes uncomfortable and a little impractical. A versatile, high performance Supermotard, yet sleek and light for everyday use. Quality, performance, advanced components and an appealing design are the keywords that describe this Aprilia Supermotard.
