Rotax DD2 Max Engine

Rotax Max DD2 racing engine. This DD2 max engine is designed to be the ultimate karting experience Rotax has to offer, with a dynamic shifting engine, endless power, and an unrivaled reliability and engine system that provides a user friendly and consistent platform. This engine is a complete engine kit, with a couple additional items needed, outlined below. Overview The Rotax DD2 Max is designed to produce a progressive power band and adaptable power for experienced racers and sportsman alike. Producing approximately 34 hp at peak performance, the DD2 can propel a full size kart to approximately 90+ mph on large tracks. The water-cooled, single-piston engine has been engineered over decades of refinement from Rotax BRP Polaris to be easy to run, easy to tune, and easy to maintain. This DD2 engine also features an onboard centrifugal clutch and multiple gears that the driver can toggle between during operation of the engine. Peak torque with the Micro Max occurs at about 10,500 RPM, but these engines can routinely rev to 15,000 RPM or more with no issues. Just keep the fuel and oil mixed, water in the radiator, and stay on top of maintenance and the DD2 Max hums along! The bare engine weighs just about 37 lbs, with complete package weighing right at 63 lbs. At the DD2 level, the engine features the 'senior' exhaust manifold (28mm in size), exhaust system, and radiator. A battery box, shifting mechanism and relays, engine relay harness, start / on / off switch, and all associated hardware to make the engine run (ECU, battery harness charger, etc) is also included in the kit. The engine also comes sealed, and with a passport, which is very important in the case that you want to utilize this engine in competitions. Take the engine to your nearest (or favorite) authorized Rotax service center in the USA for inspection, maintenance, and any items that are beyond your purview. This keeps the playing field level with the engine, further enhancing the experience with the Micro Max. What Else will I Need to Bolt this Engine on a Kart and Run It? If you are without any other accessories to put this engine on your kart, you will need: 1 Yuasa YT7BS 12v, 9 Amp Kart battery. This comes un-filled, but has a pack to fill the battery with the acid for use. A kart designed to run the DD2 engine (check with us on what models are appropriate) Rotax Exhaust support clamps (unless your kart already has them) Distilled Water (1 gallon) for the radiator 1 (5) gallon pale of racing fuel (leaded or unleaded depending on your regulations) 1 (liter) bottle of Rotax XPS kart racing oil. Note: This engine only works with very specific karts! As the axle travels through the engine and gear case, 'traditional' karts will not work with this engine.
