Aprilia RS 250 Specs

About the Aprilia RS 250

The Aprilia RS 250 was born from the brand’s total dominance in the 250cc Grand Prix class. Technically, it is built around a 249cc 90-degree V-twin engine sourced from Suzuki (the RGV250) but significantly enhanced by Aprilia with a proprietary ECU, expansion chambers, and airbox design. This resulted in a machine that produced 70 HP in a chassis that was virtually a direct copy of their GP racers. The RS 250 isn’t just a fast bike; it is a clinical instrument of precision handling. The chassis is a stunning work of art—a hand-polished aluminum-magnesium alloy twin-spar frame paired with a massive "banana" swingarm. It featured 40mm Showa or Marzocchi upside-down forks and a 298mm dual-disc Brembo braking system. With a dry weight of only 140 kg, the RS 250 offers a visceral, high-revving experience that modern four-stroke bikes simply cannot replicate. This database provides exhaustive technical details for the RS 250, including engine performance, rake and trail geometry, and the evolution of its two distinct generations. It remains the holy grail for two-stroke enthusiasts worldwide.
