You gotta’ love KTM. Chromoly steel frames, magnesium hubs, magnesium engine cases, quality shocks, Ceriani forks & triple clamps; fiberglass fuel tanks, Metzler tires, etc. etc. All the top end components which made these bikes very competitive right out of the crate.
KTM engines were considered some of the fastest air cooled 2-stroke engines ever built for their classes.
