What actually changed.

1996 → 2026 · 30 years of "progress"
KTM's smallest ADV after 7+ years of waiting 390 Duke (2013) → 390 Adventure (2020) KTM's 390 Duke roadster launched 2013. Riders begged for an ADV variant. KTM teased a 390 Adventure concept in 2017. Production version finally landed in 2020 — 7 years after the Duke. Now in its second generation (2025), it's KTM's most accessible ADV.
Bajaj-built — Indian manufacturing Cost optimisation, KTM oversight All KTM 125 / 200 / 250 / 390 / 490 single-cylinder bikes are made in India by Bajaj Auto under KTM engineering oversight. Same arrangement as Triumph Speed 400. The 390 Adventure benefits from Indian manufacturing economics — similar architecture to a £5,500 Royal Enfield Himalayan would cost £8,500+ if European-built.
21in front wheel option = serious off-road Adventure R variant Standard 390 Adventure: 19in/17in cast wheels — biased towards road. 390 Adventure R Rally: 21in/18in spoke wheels with tubeless tyres — biased towards off-road. Both share the same engine, frame, electronics. The R version has 230mm front travel vs 200mm; properly capable on green lanes.
All-new for 2025 — clean-sheet redesign Generation 2 First-gen 2020-2024 390 Adventure: trellis frame, no IMU, basic electronics. Second-gen 2025 onwards: cast aluminium subframe, longer-travel WP APEX suspension, IMU + cornering electronics, 5in TFT, ride-by-wire. Almost no parts shared with the original.
£6,499 OTR — class-leading value Vs Honda CB500X £6,799 / Royal Enfield Himalayan 450 £5,699 KTM 390 Adventure: £6,499. Royal Enfield Himalayan 450: £5,699. Honda CB500X: £6,799. Suzuki V-Strom 250SX: £4,999. The KTM offers more electronics + sharper chassis than Honda or RE; the Suzuki is the budget choice but lacks IMU.
Real off-road capability for an A2 bike Genuine 230mm travel + 21in wheel option Most A2-restricted ADVs (Honda CB500X, Royal Enfield Scram 411, Yamaha Ténéré 700 — restricted from 72bhp) have 17in or 19in front wheels and modest suspension travel. The 390 Adventure R Rally with its 21in wheel + 230mm travel is one of the few A2-license bikes you can actually take into proper trail terrain without compromise.
