What is the difference between Honda CB400 VTEC1 and Honda CB400 VTEC3?

VTEC is a patented technology of HONDA which is equivalent to SUZUKI's VC

VTEC means variable valve timing. When the engine is below 8000 rpm, there are only 4 valves per cylinder. Two machines work diagonally

And above 8,000 rpm, 4 machines work simultaneously to increase the intake and exhaust volume and improve power

But HONDA cars always accelerate smoothly, so VTEC You won’t feel such obvious acceleration when working

It just makes the machine perform more naturally at high speed

As for the VTEC1 and VTEC3, I personally think that apart from There are differences in appearance in terms of year, except for configuration upgrades of accessories

(Including changes in the position of the LCD display, the tachometer, and the layman's changes)

There is basically no difference ``````VTEC's The degree of acceleration is the same and the engine has not been significantly improved

The most important thing is the difference in year

And I personally think that those who buy VTEC have a lot of personality. ````

Because its price is almost as high as a ZX-9R even if it is a 1st generation VTEC `` Haha
