Yamaha XS400 History & Yamaha XS400 Parts

Yamaha XS400 History &  Yamaha XS400 Parts

Yamaha was riding the wave of popular 400cc engines and now reaping the benefits of the XS series as well. It is therefore not a surprise that their engineers wanted to combine the two to create an ideal bike. Evolving directly from the earlier XS360 model, Yamaha XS400D was introduced to US market in 1977 and to Europe in early 1978. It was advertised as a commuter model, targeting students and low-income motorcyclists.

First Yamaha XS400D

It had four stroke aircooled twin engine which powered the single overhead camshaft by chain. The engine and 6 disc clutch, was fitted together into the horizontally split crankcase so typical for XS series. Early XS400 had points ignition system and electric starter backed up with manual kickstart. The engine with pair of 34mm Mikuni carbs was fitted into a tubular steel frame with dual cradle. First XS400s also had squared-off 11l fuel tank, non-adjustable telescopic forks at front and swingarm with 5way adjustable shocks at rear. The 1978 XS400 became immediate bestseller in Germany and continental Europe.

As with many models, Yamaha was trying various features to see what suited their customers at different markets like self-cancelling indicators, kickstart only on economy XS400s, also editions such as Special, Special II. & Heritage. But generally speaking, there were the following changes throughout the time:

1979 XS400F received a teardrop 16l tank and slightly stepped seat, swing arm was extended by 40mm, cast alloy wheels and drum brakes fitted at rear

1980 XS400SG / SE got even more “cruiser like” appearance with deeper step on the seat, pull back bars, 16” rim at rear wheel, improved exhaust system and other cosmetic changes

1982 XS400R Seca was ultimately a different design altogether. It was meant to be the highlight of the series with two overhead camshafts, new Yamaha induction control system (YICS), black narrower engine with alternator laid over the gearbox, hydraulic telescopic front forks, monoshock swing arms at rear and brand new tank design with even larger capacity.
