A trail-going enduro version of KTM's motocross 125, with enduro bodywork, a centre stand and a side stand. The page's only commentary is a French magazine test from the 1984 era, which praises the bike's light weight, strong acceleration in sand and technical sections, and the ability to be pushed up steep climbs, while noting that its braking was only adequate.
