Differ but not too different, the CA is configured with dual carburetors and the CMX only has a single carburetor. They look different but they share parts, its difficult to get any clear information on the differences other then the CA may have been a version of the engine sold in Asian markets only?


I am not sure if they ever offered CA version in the USA, the CA version can be found in Australia. They were both sold as Rebels that had a few differences.
