I've come across this rumour in Pak society that motorbikes ranging from 1991 models and before are much stronger/better when it comes to engine performance. Is there any truth to this?
As we know, people in Pakistan love to believe in rumours compared verified and researched facts. So which one is it? Motorcycles from the 90s and beyond have the clear advantage in terms of CDI injection and fuelefficient technologies like Euro 2.
So ss there any reality to pre 91 engines being better in performance whatsoever? And if so, how come?
(Also, I'm strictly speaking of 4 stroke bikes)
