Finding an engine with enough power for your model is easy. Finding an engine that offers you more than the DLE-40 Twin? That's next to impossible.
DLE offers the ease and efficiency of electronic ignition, the smooth operation and long life of an opposed twin and the incredible bang-for-the-buck that all DLE engines offer. Features that are extras on other engines are standard equipment on DLE engines. They run from high-dollar items such as electronic ignition and muffler(s) down to conveniences like mounts, spark plugs and connectors.
