The power/weight ratio was a bit better in 1986 0,39 hp/kg (0,18 hp/lbs). The upgraded Suzuki GSX-R 400 new chassis, shorter wheelbase and was totally redesigned. I fact, you could say it was a totally new bike. It even got a new internal model code: GK71F (presented in March 1986).

The 1986 and 1987 year’s engines differ from the other models, they do not have the normal type of liquid-cooled engines. Instead they the use the SATCS (Suzuki Advanced Three-way Cooling System) that used water, oil and air to keep the engine from overheating.

The 1986 year’s GSX-R400 (Type 3) had a single square headlight instead of two round headlights. The new front design didn’t gain popularity and the twin headlight were reintroduced the following year.
