The long-stroke ER four-cylinder engine, The lower powered engines in the commercial "Pro" series had a lower compression, a distributor rather than the distributorless coil pack setup found in the passenger cars, and a manual choke.

JDM versions included a triple-barrel carburetted version for the Accord (110 PS or 81 kW or 108 hp at 5,800 rpm) and one with Honda PGM-FI which produced 130 PS (96 kW; 128 hp) at 5,800 rpm.
