Welcome,

This website was created to provide information about Rotax engines with rotary valve that where used during the 70’s, 80’s and 90's by various motorcycles manufacturers. These manufacturers understood the quality and the potential of this Austrian made engine. Unfortunately, technology moved on and the possibility that we will ever see a new rotary valve engine in a motorcycle on road or track is to be neglected. This website is mainly about enduro and motorcross bikes, because that was the main application for these engines. A lot of manufactures also fabricated road, trial, racing and military bikes with these engines. Karts where also equipped with this power source. Because i get a lot of requests for Rotax 256 tandemtwin (and luckily own one myself), i plan to include more  information about this engine soon. If you have any questions feel free to contact me
at the email-adress below or write a message on the forum.

Keep revving!
