2011 Aprilia RS4 125

$6,000 + ORC

The Aprilia RS4 125 was first manufactured in 2011, as a replacement for its extremely popular RS125, the two stroke race replica. The change was quite significant, as Aprilia switched from their Two-Stroke engine that was seen on the RS125 through its life to a more reliable and fuel efficient Four Stroke engine. The bike also looked far more modern for the times, with much more sleek angles.

The powerplant is an electronically fuel-injected 4 stroke 4 valve DOHC single cylinder, with a balance shaft. A race kit is available from the manufacturer that boosts power from the standard 15 bhp to 25 bhp.

The RS4 125 is available with a quick-shift system similar to the RSV4, in which the engine halts the torque from the engine based on engine rpm, the amount of throttle being applied, and the speed of the bike. This system allows smooth, fast upshifts without the use of the clutch. This is optional on the standard bike, but included with the GP Replica model.

The chassis is an aluminum perimeter frame with an aluminum swingarm. The brakes consist of a 30 cm steel disc in front with a four-piston radial caliper, and a 22 cm steel disc with a single caliper at the rear. Complementing this for 2017 is Bosch 9.1ML single channel ABS, at the front.

The Aprilia RS4 125 is still in production today. Due to its high production quality, it is very highly regarded as one of the best 125 4-Strokes to buy.
