The design rights to the Rotax 654 were bought out by Loncin a few years ago, If your bike is a 2009 or 2010 then most of the engine internals will have been shipped to China from Austria for assembly but after 2010 the whole engine was made in China. As the rights are owned by Loncin they can badge the motor as Rotax. Loncin also manufacture other engines under the guise of Rotax China which are sold for light aircraft that Rotax Austria does not serve.
