Aprilia RS 250 (2002 - 2003)

The Aprilia RS 250 is a relic of a bygone era, a testament to the raw power and agility that defined the two-stroke era. Its reed-valve motor, a direct descendant of the 1993 250GP winner, produces a sweet perfume-like sound that’s music to the ears.

Built around a near-perfect chassis, the RS 250 is a handling machine par excellence. With its upside-down forks, banana swingarm, and Brembo four-piston brakes, it’s a combination of talent that’s unmatched in the world of motorcycling.

The single crank V-twin stroker engine may require some finesse to extract its full potential, but when you hit perfect pitch at 10,500rpm, delivering 55bhp with a sweet punch, it’s pure riding nirvana.
