KTM 390 Duke Variants Explained: Key Differences, And Similarities

KTM India has introduced a new 350 cc version of the 390 Duke to leverage the lower 18 per cent GST slab for engines under 350 cc, positioning it alongside the existing 399 cc model now badged as 390 Duke R. This move makes the standard variant more accessible while retaining core performance traits.
