Which one you will suggest to a non-technical person? What are the merits & demerits of these two types of engines for bikes? Which one is more fuel efficient? I am a teacher, I want to buy a new bike in next month, I am having a scooter at present. Can anyone suggest me which bike I should go for? A bike with two stroke engine or with a four stroke engine?
