30-Year Arcs / Modern Naked / Hyosung GT650 Lineage
Hyosung Japan

Hyosung GT650 / GT650R. The Korean budget V-twin alternative.

Hyosung's 2005 GT650 was Korea's V-twin sportsbike — 647cc V-twin (Suzuki SV650-derived), naked (GT650) or faired (GT650R), very low new prices. Significantly cheaper than SV650/SV650S at launch. Killed in 2017 by Euro 4 emissions. Hyosung brand absorbed by KR Motors then mostly dormant in 2026.

What actually changed.

Korean V-twin budget sport · 2005-2017
Korean V-twin budget alternative 2005-2017 Hyosung GT650 was the cheapest V-twin sportbike in the UK at launch — £3,899 in 2005 vs Suzuki SV650 at £4,599 (£700 saving). Same general engine layout (90° V-twin, 645/647cc), Korean build. Sold on price; reliability was variable but acceptable. Killed when SV650 dropped to similar pricing and Euro 4 added emissions cost.
Why it ended 2017 Euro 4 + parent struggles Euro 4 in 2017 required engine update Hyosung couldn't fund through their parent company's financial struggles. Brand absorbed by KR Motors but no significant production since. The Korean motorcycle industry never broke through against Japanese volumes.
vs SV650 in 2026 Same engine concept SV650 (645cc V-twin, 75bhp, 197kg wet, £6,799): modern, refined, factory parts. GT650 (647cc V-twin, 78bhp, 210kg wet, £2-3.2k used): cheaper, Korean parts, more variable reliability. Same general engine layout, very different ownership experience.
Real cost trajectory −9% real (vs SV650) £3,899 GT650 in 2005 (£6,900 today) → £6,799 SV650 in 2026. Modern SV650 is cheaper than the GT650 was in real terms — Suzuki dropped pricing on the SV to compete. Used market in 2026: GT650 £1.2-2.5k early, £2-3.2k late for clean.
Rider aids count 0-1 GT650 (2005-2008) had carbs, no electronics. GT650 (2008+) added FI. ABS option from 2014. Pure budget Korean specification.
Cheapest way in £1.2k A clean GT650 from 2005-2008. 78bhp V-twin, naked, very low purchase price. Pay attention to electrics, reg/rec, parts availability (Hyosung-specific parts can be slow). The cheapest V-twin sportbike on the UK used market — for now.
