The '''[[Suzuki]] RM400''' was a Air-cooled, Single Cylinder, Two-stroke Trial [[motorcycle]] produced by [[Suzuki]] in 1978. Max [[torque]] was 3.69 ft/lbs (5.0 Nm) @ 6000 RPM. Claimed [[horsepower]] was 43.05 HP (32.1 KW) @ 6500 RPM.

==History==
 +
The RM (standing for racing motorcycles) series of Moto-Cross machines were launched in 1975, replacing the old TM models. The range ran from 50cc right up to 400cc, and were very successful off the back of Suzuki’s World championship winning works machinery. By 1981 the models adopted liquid-cooling and the Full Floater swing-arm, a giant evolutionary leap in the handling stakes, giving Suzuki a real edge against the competition at that time. Manufactured from 1978 to 1980, the machine had an air cooled, single cylinder two-stroke engine with a displacement of 402cc and a 6.7:1 compression ratio.
 +
 +
==Engine==
 +
A 80.0mm [[bore]] x 80.0mm [[stroke]] result in a [[displacement]] of just 402.0 cubic centimeters. 
 +
 +
==Drive==
 +
The bike has a 5-Speed transmission. Power was moderated via the Wet, multiplate. 
 +
 +
==Chassis==
 +
It came with a 3.00-21-4PR front [[tire]] and a 4.50-18-4PR rear tire. Stopping was achieved via Drum in the front and a Drum in the rear. The front suspension was a  Air/oil-damped, Leading Axle while the rear was equipped with a Aluminum Box Type, Gas-oil Shocks. The wheelbase was 57.09 inches (1450 mm) long.
