Aprilia RS 125 Replica GP. The technological heart of the Aprilia RS 125 is a 4-valve distribution, liquid-cooled single cylinder with completely revamped thermodynamics. It delivers a more robust torque curve, with maximum power reached at lower revs, meaning reduced fuel consumption. The new engine is Euro 5-compliant, for outstanding performance that doesn’t come at the cost of the environment. The Aprilia RS 125 promises a riding position that is truly sporty, with no compromises, no shortcuts taken. The foot pegs are designed to avoid fatigue, the handlebar is placed so that the rider has total control of the bike, with the clip-ons raised by 18 mm for greater comfort. The Aprilia RS 125 also sports a new digital instrument display, packed with data such as fuel level indicator, instantaneous and average fuel consumption, remaining mileage and much more.
