When the bike first came out, I don't think Honda anticipated the degree in which accessories were to be added. The police model had a larger heatsinc on the rectifier but that was about it. The first generation ABS added some potential current draw. The oil cooling style of alternator with an outboard regulator/alternator was designed to charge at that high rate. Possibly Honda got the message that folk were adding power consuming lights and heated gear and something needed to change. The Gen II ABS possibly also drew more current and an upgrade was apparent. All conjecture on my part. This bike was designed in the late 80's to fit a niche market, basically remained unchanged except for GenII ABS, larger forks and front tire for GenII ABS, larger alternator and some cosmetic pieces in the Tupperware to allow better access to the rear shock. It had a good run from 1990-2002 (2003 Police model)
