The Evolution Big Twin Harley-Davidson engine with 1340 ccm, not to be mixed up with the Sportster engine of the same name, was used in all large H-D cruisers between 1984 and 1999 and replaced the Shovelhead. This was followed by the change to the new Twin Cam engines. This gallery contains all Thunderbike conversions with Evo engines.
