It is 4.
Yes, a YZ 250 is a 2 stroke, a YZ 250F is a 4 stroke.
yes a yz is two stroke so any yz is 2 stroke but if it has an f on the end its a 4 stroke so a yz250 is two stroke a yz250f is 4 stroke
a yz what engine size? Probably about 2-4 seconds IF you can hang on AND keep it on the ground long enough to shift gears.
(z - 4)(x + y)
Not likely, ttr 125s are 4 stroke and it is a trail bike. a yz 125 is a 2 stroke race bike. yz 125s are worth more unless you trade for a older model then the ttr. its posable but highly unlikely
750ml - 3/4 of a quart
78 + yz = yz + 78
yz
NO
different cc
2(xy+xz+yz)=100 xy+xz+yz=50 or x(y+z)+yz=50 x=2, y=4, z=7
yz 85 will smoke it!!
