Notes

Grew to 656cc for the 1990 kei size increase. Sold in three states of tune: a carburetted version, a fuel-injected PGM-FI version, and the high-output MTREC version with individual throttle bodies. The Beat's mid-mounted MTREC unit revved to roughly 8100 rpm and made 64 PS, the kei self-regulation ceiling of the era.
