Hyosung Gt650r
The Hyosung Gt650r has a top speed of 185 km/h (estimated; note: varies by market tune and rider conditions), produces 69 hp and weighs 209 kg. Motoryk rates it 6.5/10.
The Hyosung GT650R was introduced by South Korean manufacturer Hyosung in 2005 as a sportbike aimed at the mid-range market, offering a twin-cylinder engine at an accessible price point. It was notable for being one of the first Korean-built sportbikes to gain significant international attention, sold in markets across Asia, Australia, Europe, and North America. The model helped establish Hyosung's credibility as a motorcycle manufacturer, though it faced some criticism over build quality and reliability in early production years before improvements were made in later revisions.

What Buyers Should Know
Watch the Regulator/Rectifier
The GT650R is known for premature regulator/rectifier failures, which can kill the battery and leave you stranded. Budget for an upgraded unit as a preventive measure, especially on pre-2010 models.
Low Resale Value
Hyosung's reputation for inconsistent quality means resale values drop significantly, making used examples very affordable to buy. However, this also means you'll recover little value if you sell it later.
Genuine V-Twin Engine
The GT650R features a real 647cc V-twin engine inspired by Suzuki's SV650 design, delivering enjoyable torque and a sporty riding experience at a fraction of the cost of Japanese competitors.
Generations & Specs by Year
Initial release with 647cc V-twin, carbureted engine, tubular steel frame, conventional forks.
"Korean ambition, Japanese polish still missing."
The GT650R looked the part parked next to an R6 and for the money in 2006, nothing touched it on raw spec sheet value — a genuine 647cc liquid-cooled V-twin for beginner-intermediate money felt like theft. But living with it exposed the cracks fast: the Mikuni carbs needed constant jetting attention in cold mornings, the paint bubbled around the tank seams within a year, and the suspension was so undersprung it went vague mid-corner on anything but glass-smooth tarmac. I put 18,000 km on mine and never felt truly confident tipping it into a fast sweeper, yet the torquey V-twin pull from 4,000 rpm up was genuinely satisfying on open roads and kept me coming back despite the frustrations.
Pros
Cons
Fuel injection introduced, revised bodywork, updated suspension, improved braking system, Euro compliance updates.
Further emissions updates, minor cosmetic revisions, refined fuel injection mapping, updated color schemes.
Used Buyer Review
"Decent budget sportbike that demands a very careful pre-purchase inspection."
$1,500-$3,500 usedThe GT650R is South Korea's answer to the entry-level sportbike question, and honestly? It's not a bad answer. Hyosung licensed Suzuki's SV650 engine architecture and built something genuinely capable around it. The parallel-twin pulls cleanly from low revs, the riding position is aggressive without being punishing, and the thing actually looks the part. For the money — usually well under two grand used — it's hard to argue with the sheer volume of motorcycle you're getting. Here's the honest part though: reliability is a lottery. Early models (pre-2010 especially) had well-documented carburetor issues, electrical gremlins, and parts that felt like they were specced on a budget. Because they were. Find one with a documented service history and you'll probably be fine. Find one that's been neglected and you're signing up for a project bike that Korean parts availability will make miserable. Always check the regulator/rectifier — it's the first thing to cook itself. For a new rider who wants sportbike looks without sportbike insurance costs, the GT650R makes sense. Just buy the right example.
