RS125 Engine used (NF4)
RS125 Engine used (NF4)
: $1,250.00

Used NF4 Honda RS125 engine. History is unknown, so assume it will need a full rebuild.
Cylinder, head, transmission, internal clutch and gears all look in good shape. Engine stamp indicates it's a 1991 motor, but should work in all NF4 model bikes.

This would be a great way to have a lot of spares that you can't buy new from Honda anymore.
