Yamaha SR400 was king of the road from 1978 to 2018 which was powered by a 399cc, single-cylinder, air-cooled, SOHC, 2-valve engine hip classic.
SR400 a younger sibling to SR500 was a typical kick-starter. One of the most important aspects of this bike was to store the engine oil in the frame. The frame also housed the cooling system.
This made the bike more efficient in terms of not having any external oil reservoir and saved the space. It also allowed increasing the ground clearance as well as reducing pumping loss.
With 27.4 NM @ 3000 rpm of Torque, the bike had a top speed of 129 kmp/h and carried a wet weight of 174 kg. Those are some impressive specs for a single cylinder.
SR400 came with aluminium rims and spoked wheels. The analogue speedometer and tacho with trademark steel bezel.
The speedo showcased details like blinkers, low fuel warning, engine trouble indicator, gear positions and headlight high beam indicators.
On the left side, it had all the important functions like horn, hazard, flash to pass button, low and high beam button. The right had an engine kill button.
Another good feature Yamaha SR400 had if the engine is left idle, it had an automatic cut after more than 20 minutes.
Further, the exhausts had a coat of nanofilm so as not to rust, and it also had a 3-way honeycomb-type catalytic converter.
We had rumours that Yamaha wants to resurrects this machine. However, we don’t see it happening, which does mean Yamaha will discontinue it.
