yes it can i have done it
Should fit it's the same generation motor.
nope. You problably could by doing some frame cutting .
The 85 had a 305 as an option....so yes. It will fit. However, the computer and possibly the transmission will have to be replaced. The motor mounts will also have to be moved to the correct location....which should already be drilled in the frame.
no
No, I do not think so.
yup
no the 1985 kx 125 cylinder will only fit years 85-87 kx 125s
The 85 & up may fit with some mods. Look at the bolt up for both bikes
The cab and front sheet metal will fit but you will have to bobb your bed about 11 inches shorter.
85% of 125= 85% * 125= 0.85 * 125= 106.25
A direct bolt on, no.
if you use the computer if the 85 is efi
