It's how the engines work. for the same amount of power, a 2-stroke will be lighter, smaller and rev higher. It'll also use more fuel and pollute more.
A 4-stroke will run cleaner and more efficiently. It'll make more torque but won't rev as high.
if you have a 4stroke dirt bike you run straight gas ,if you have a 2stroke dirt bike you run mixed gas
oil+gas=2stroke gas only in the tank=4stroke
if it is a 2stroke it can go like 90+ depending on the condition of the bike. if its a 4stroke it can go about 80 on the road
a racing 2stroke dirt bike
yes if it is 4stroke witch i think ttr 90 is! use good type of gas, you have separate place for engine oil, but with 2stroke engines you have to mix gas and oil together.
klx110 or kx110? i forget which one is 2 and 4
3.37hp? that cant be a dirtbike. its problably a little poket bike or somthing, but im assuming about 20mph
A 90cc are 125cc 4stroke
30 mph - 40 mph
It more than likely does not have one. Rarely does a dirt bike have an oil filter. Your owner's manual will list the location if it has one.
Depends on weight/height. At thirteen I rode a 125 4stroke trail bike and an 85 two stroke racebike
the main difference is a two stroke has oil mixed into the gas weather it is oil injected or pre mixed(adding oil to gas yourself). a two stroke has no intake or exhaust valves,no pushrods,or rockerarms. intake and exhaust into the combustion chamber in done through the sides of the cyllinder walls.
