Crf150r is faster with a top speed around 72mph, vs. 55-60mph for the kx100, depending on rider weight/etc.
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
For the same engine size, it should be.
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.
Be a druid. Swim like a seal.
it runs faster than a 4stroke but use mixed gas in the to stroke
