The REDS R5R Racer v3.0 is the perfect synthesis of innovation and technology, with a mid range street price. Loaded with features for 2016, the R5R Racer is one of the most advanced, innovative and cost effective engines on the market.

The Racer is equipped with the HCX horizontal carburetor, a silicone filled and tuned crankshaft, and sleeve with 5 inlet ports and classic exhaust port, combined with a high sealing front bearing, and high quality rear chrome steel bearing. All the parts have been matched and measured by Mario to fall within strict tolerances, and hand built by Mario personally.

  • LIGHTWEIGHT & LOW GRAVITY CENTER: The REDS Factory Tuned line was designed to be not only more powerful and reliable but lighter and with lower center of gravity than ever before. To do that, they started from scratch, redesigning each essential part like crankcase, cooling head, combustion chamber and backplate.
  • HANDMADE, TUNED AND ASSEMBLED by Mario Rossi: All parts are matched, measured by Mario Rossi within certain tolerances, hand built and Tuned by him personally. The engine leaves the factory with a hand inspection of all components and compression is checked.
  • LONG STROKE: The R5R crankshaft is surprisingly strong and reliable thanks to a special steel and heat treatment. Special silicone filling reduces rotating mass.
  • 5 PORTS CLASSIC: R5R sleeve design and timing features high torque and controllable power delivery in order to make the engine extremely drivable, suitable for every type of track and to help reduce fuel consumption.
  • FLAT BILLET PISTON: The flat piston matched to a specific combustion chamber guarantees high performance and low consumption. The connecting rod is lightweight, durable and reliable, and the slim shape is designed to minimize aerodynamic friction.
  • HIGH QUALITY BALL BEARINGS: The high sealing and high reliability made in Japan front ball bearing ensures high idle stability. The steel Swiss Made rear bearing ensures longer life and low friction at high temperatures.
