MORE THAN A SUCCESS. A LEGEND
After the success obtained over a twenty year period on both a commercial and sports level with RS 125 with a 2-stroke engine, (from 1993 to the present in more than 100,000 units and sold in more than 30 countries around the world), in 2011 Aprilia introduced its first eighth of a litre 4-stroke, directly derived from the RSV4, several times World Superbike champion. RS4 125 quickly became the most beloved and sought after sport bike among young people, who were immediately won over by its performance, safety and riding characteristics of a pure racer, placed at the service of daily mobility.
Aprilia is universally recognised as the manufacturer of ultra-fine chassis and the RS4 Replica versions are no exception. The frame is created based on the exceptional experience gained over the years in top level racing and it adopts die cast aluminium spars with crossed reinforcement ribs.
A lightweight structure, but at the same time with torsional rigidity, capable of providing complete control even in track use.
The suspension system is top level: the sturdy 41 mm upside down fork with black anodised sleeves has a stroke of 110 mm, while the rear monoshock is fixed directly to the asymmetrical swingarm.
Braking system at the top of their class: the 300 mm steel disc at the front, gripped by a four piston radial calliper, works together with a 220 mm disc at the rear with a single piston calliper. The 17" wheel rims” with six spokes are shod with 100/80 rubber up front and 130/70 at the rear.
The refined chassis house latest generation engines. The Aprilia RS4 125 Replica is powered by a 125 cc 4 stroke, water cooled, single cylinder engine with four valves and electronic engine boasting a sophisticated double overhead camshaft (DOHC) valve timing system.
This ensures not only the maximum power output permitted for the class, but also a smooth, linear delivery which is environmentally friendly, complying with the strictest emissions regulations.
