Question

What kind of engine is best for offroad vehicles such as Dirtbikes and ATV's? 2 stroke or 4 stroke? And why?

Answer 1

2 stroke = 2 strong legs powering a mountain bike. It's the best off road machine available.

Answer 2

Why post your Q. at a bicycle section?  Are you a stroke victim?  

Answer 3

Post this question in the motorcycle section.

Answer 4

usually, on mini bikes, they use 2 stoke 49cc engines. this is because the 2 stoke accelerates faster because of: A two stoke engine is litterally 2 strokes. the plan is: compression, expansion, that is two storkes. one to put the fuel and air in, then one to expand. the our stoke engines are also much more expensive.  a four stroke is basically the same process, but it is MUCH MUCH MUCH more efficient. the problem about the 2 stokes is that not all of the gas is burned, so fuel is occasionally spewed out of the exaust pipe. the cycle for the 4 stroke is: intake (air) compression (air and gas) expansion (explosion in the cylinder) and exhaust (the left over from the expansion). although, many of the older boat engines and some of the older ATV and dirt bikes use the four stoke engines, but now, the EPA makes the engines be very efficient, so all (most) of the new engines are all four stoke.

welll, theres ur answer.
