An aluminium alloy perimeter beam frame holds an advanced liquid-cooled two-stroke engine. The 125cc single-cylinder motor uses a ceramic-type coating on the cylinder to cut friction and wear, while modern intake and exhaust designs boost power to over 194kW (260bhp)/litre. The aerodynamic fairing echoes the designs of Apt-ilia's GP machinery, and there have been various race-replica paint schemes. The RS125 has a high-specification chassis design, with wide, sporty tyres, 40mm (0.8in) upside-down front forks and an aluminium swingarm with adjustable monoshock rear suspension, giving fine handling especially on the track. |
