 Aprilia's RS125 lightweight sports bike has been completely revised for 2006 using technology from the company's successful 125cc GP machines and re-styled, after extensive wind-tunnel research, to emphasise its family resemblance to Aprilia's RSV1000 Factory litre-class sport flagship, with twin halogen headlights.

The 2006 model has new 40mm inverted front forks with an RSV Factory-style forged lower triple, and a 320mm, fully floating, front disc brake with a four-piston radial mount calliper. A radial master cylinder modulates deceleration via braided stainless-steel brake hoses. A radial master cylinder modulates deceleration via braided stainless-steel brake hoses.

It has an oval-section, racing silencer with riveted end plates and a catalytic converter so that it complies with Euro 2 emissions regulations.

The cast-alloy wheels are styled to resemble the crossed-spoke, forged magnesium OZ rims used on the RSV1000 Factory and anodised the same bright blue.

The RS125 also comes with a new analog/digital instrument panel from the RSV1000 with a multi-function display that includes speedometer, coolant temperature gauge and lap timer – there's even provisional for trackside optical telemetry.

The frame is made of cast aluminium alloy with cross-ribbing reinforcement and the box-section, aluminium alloy swing-arm is asymmetrical to allow the exhaust to be tucked as close as possible to the chassis, to increase Ground Clearance
