Features

• The SR 50 includes technical components typically found on supersport racing motorcycles. Inspired by Aprilia's own RSV 1000 R, the Replica was the first scooter to feature 13-inch wheels. Other innovations include the first liquid-cooled scooter engine, with direct injection, and the industry's first double disc brake system. A lower-priced, simplified version of the R Factory, the Replica does not have a transponder and features a different engine with analog-digital instruments.
  
  

Engine

• A carburetor-fed, single-cylinder, two-stroke engine powers the 2011 Replica scooter. (By comparison, the R Factory contains a fuel-injected Purejet engine.) The Replica's engine displaces 49 cc and features a 12.1-to-1 compression ratio. An automatic gearbox and capacitor discharge ignition (CDI) are standard features.
  
  

Chassis

• Replica scooters share a high-tensile-strength steel tube frame with the R Factory. The single-cradle frame allows for greater-than-average front wheel feedback due to higher wheel loading. Single 7.5-inch front and rear disc brakes, light alloy wheels and low-profile tires provide solid grip and handling. At the rear, the engine unit acts as a swing arm and provides 2.75 inches of suspension travel.
