Rotax Motorcycle Engines

There is no stopping Rotax. Never satisfied with the latest achievement, it is not surprising to see how BRP-Rotax has conquered the motorcycle engine sector, worldwide today. Let us know all about Rotax motorcycle engines.

Why do the world's leading motorcycle manufacturers choose only ROTAX 2- and 4-stroke engines? For the simple reason that before ROTAX started supplying top-of-the-line motorcycle engines in the early 1980s, it has started building LOHNER scooter engines ever since the 1950. Striving for maximum performance and outstanding reliability, one only has to take a look at the this innovative history of BRP-Rotax.

Blowing the competition away

The V990 powers one of the fastest twin-cylinder motorcycles on the track, proven by comparative testing. With a 139 horsepower and an extremely compact design (60° cylinder angle), it's built for speed. Some innovations like the cutting-edge mass-balancing system with double countershafts for limiting vibrations put it way ahead of its competitors. The Pneumatic Power Clutch to control rear wheel bounce is also important to take note of. The magnesium cylinder head and clutch covers help reduce the weight of the engine to an absolute minimum.

Well if you still want more, try the 650 cc single-cylinder. Getting acclaimed as the best one-cylinder motorcycle engine in the world, no one can surpass it in performance, torque and reliability. Its simplicity and compactness combine to create truly superior handling.

ROTAX motorcycle engines' have many other advantages too, like the reduced vibrations thanks to the balance shaft, which increases riding comfort and user-friendliness. Exceeding the expectations of their clients, these ROTAX motorcycle engines are tailor-made. Customized to meet the various requirements of the clients, they are the power behind the world's most exciting motorcycles.

For example, the 1125 cc Helicon engine was developed for Buell and is a lightweight, fast-revving, big-bore, short-stroke V-twin with a broad power curve peaking at 146 hp (109 kW) near the 10,500 rpm redline. The twin-cylinder, 139 hp (104 kW) V990, is light and compact, sporting magnesium cylinder head and clutch covers. The Type 122 & 123 engines are single cylinder 125 cc engines as used in Aprilia AF1 / RS125 models. Using an exhaust valve system called Rave to increase peak power while retaining low end torque, these are high revving with high power units.
