Rm125 1986

Recommended Posts

Rm's have had disc front brakes since 1985 - 1986 was the first year of that new look - motor is unique to that year top end has AEC power valve has a rotating drum that opens into a chamer on the cyliner head. It is open at low rpms to increase header pipe volume similar to how the honda atac system worked. 86 also had non cartridge kyb tvc forks and remote res shock and the linkage for the shock was also a one year item. '87 has different top end and power valve and shock / linkage and cartridge forks but visually similar an 87 is more like an '88 the '86 was pretty much a one year bike.
