History of motorcycles

completely original motion, comes from a private collection in Mantua,we have checked the bike, everything very well funsiona, to use right away


In 1983 Freddie Spencer, riding for Honda, became the youngest 500cc World Champion ever. Two years later, in belated celebration, Honda released the NS400, a bike claimed to be a road-going replica of Spencer's machine. The result is a fast, small, very light, two-stroke sports bike, beautifully finished with quite outstanding handling and road-holding. It may be 100cc smaller and considerably less powerful than the brutal all-or-nothing factory racer but they genuinely do have enough in common to warrant the Grand Prix replica tag. Like the racer, the NS400 is a liquid-cooled, three cylinder two-stroke of an unusual configuration, a V3.

The outer pair of cylinders are arranged forwards and down with a vertical middle cylinder. It is a light, narrow unit, no wider than a parallel twin. The 90 degree, V3 layout allows the chassis to be kept extremely compact. Mounted in a lightweight aluminium box-section frame, the engine weight is low and carried forward to give a good centre of gravity. The carburettors are carefully arranged inside the V to keep the engine short, hence the wheelbase can be kept short too. Weighing only 3591b with a 54.5in wheel-base, the NS is the lightest and quickest bike in its class. It is fast, nimble and responsive. You can change lines on it as quickly as on a genuine racer.


Unlike many sporting two-strokes, the power the NS makes is not that peaky or rough. Honda use their own version of an exhaust power valve called AT AC (auto-controlled torque amplification chambers) on the front two cylinders to help the power spread at low revs. Even so there is little or no acceleration below 5,000rpm but there is a gradual build up between 5,000 and 7,000rpm, at which point it starts accelerating Ike crazy, screaming revs all the way to the redline. Surprisingly, it does this smoothly. If any two-stroke can be said to have manners, then the NS has more than most.
