Still powered by the LJ50 engine also used in its predecessor, the Jimny 550 was by a sizable margin the last two-stroke car engine built in Japan. Production ended with the withdrawal of type approval in November 1987 in favor of its F5A-engined brother, the JA71. The two-stroke had been favored by Japanese off-roaders (and by Suzuki) due to its light weight and superior low-speed torque.[15]
