4 stroke
Yes it is a 2 stroke dirt bike manufactured by Kawasaki.
Both nice bikes but the kx100 without a doubt. the kx is a 2 stroke motocross bike designed for racing. A xr100r is a four stroke trail bike with much less power.

i say that a 4 stroke is faster than a 2 stroke
The yz would always win because its a 2 stroke race bike. Even the yz85 would beat the crf150r or the crf150f.
A YZ250 is much faster than a CRF250r. The YZ250 is a 2 stroke where as the CRF250r is a four stroke.
The 2 stroke will be faster because of differences in Waite but more polluting be it oil mixed with fuel
Oil is a lubricant. 2 stroke oil is designed to be mixed with gasoline and in that form it lubricates the engine. 4 stroke oil lubricates the engine but is not burned as 2 stroke oil is. This has nothing to do with speed. So, the answer to your question is neither is faster as they are just lubricants.
For the same engine size, it should be.

tht all depends on the type of chassis and engine set up. a 2 stroke is going to have a great advantage off of the start but will require more rpms to keep it going at highr speeds because 2 strokes produce lower torque at hihger rpms. 4 strokes on the other hand lack that initial punch of power right off of the line, but they have a much wider torque range also called a power band. This wide range of torque gives a 4 stroke the advantage in that they require a lot less shifting when leading into an out of corners. 2 stroke is more faster than 4 stroke,because it have only 2 combustions.In general a 2 stroke engine will be quicker than a 4 stroke engine of the same displacement. The answer is a little more complicated than that if you look into the details.a 2 stroke because its lighter and has more torque-------------Generally, 2 stroke dirt bikes are much faster and lighter than 4 strokes, and have much more torque. But 4 strokes have more power and a higher top speed. For example, a 2-stroke 85cc dirt bike (like the YZ85) will be equal to a high performance 150cc dirt bike (like the CRF150R).
