Now, Aprilia introduces a smaller, lighter parallel-twin in the form of the RS 457 shown.
With 457cc, a claimed 47 horsepower and 350 pounds of dry weight, this looks to be a nimble, entertaining mount.
The engine is a stressed member in the aluminum twin-spar frame, and the fork and shock are adjustable for spring preload.
The wheel sizes are designed to keep the bike light and nimble, with a 110/70-17 front tire and a 150/60-17 rear. A single 320mm front brake rotor is squeezed by a four-piston caliper.
It is an Aprilia, so we are not surprised that it has relatively sophisticated electronic aides. Three-level traction control and three riding modes operate through a ride-by-wire throttle. A modern 5″ TFT instrument display is featured.
No other specifications are available as of this writing, and the pricing and availability information are yet to be announced.
