The liquid-cooled successor to the RD400, sold as RD350LC in Europe and RZ350 in other markets. Its bottom end owes more to the RD400 than to the TZ350 racer, and the single diagonal rear shock under the seat replaced the old twin-shock layout. Power is modest below about 6000 rpm and arrives with a sudden surge above it.
