This LC4-based off-road nameplate emerged in the mid-1990s as part of the brand’s push to make its competition-bred four-stroke singles more widely available to riders outside pure factory racing. Early parts and decal references show the nameplate appearing by model year 1994, when it was used on the larger-displacement LC4 enduro machines that helped define the brand’s hard-edged, race-oriented dirt-bike image.
Over the next several seasons, the bike evolved along with KTM’s LC4 family, which was central to the company’s off-road and dual-purpose efforts during that era. The naming shifted slightly across the run, with catalogue listings showing variants such as 620 Competition, later 620 Competition Limited 20kW for certain European markets, and 620 LC-4 Competition by the end of the decade. That progression reflects the same basic machine being updated rather than a separate revived lineage.
By the 1999 model year, the nameplate was still present in KTM parts catalogues, but the 2000 model year brought a move toward SC badging instead, indicating the Competition name itself had reached the end of its continuous production run. As a result, this is best understood as a single 1990s-era competition-focused LC4 chapter rather than a long-running badge that continued unchanged into the modern lineup. The nameplate remains notable among enthusiasts because it sits close to the roots of KTM’s later dominance in enduro and rally-style off-road motorcycles.
