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
No, the lower unit from an 85 hp Force outboard motor will not fit a 125 hp Force outboard motor. Lower units are typically designed specifically for each engine model and may have different gear ratios, bolt patterns, and dimensions. It's best to match the lower unit with the correct engine model for proper fit and performance.
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.
