The Hyosung GT250R is a 249 cc (15.2 cu in) motorcycle manufactured by Hyosung Motors & Machinery Inc. It entered the market in 2005, offering a 250 cc class sport bike with a frame similar in size to Hyosung's larger GT650 sport bike.

Engine[edit]

The GT250R comes stock with a 249 cc V-twin engine.[4] The Hyosung V-twin engine was designed in Hamamatsu Japan by a design team consisting of engineers who have previously worked in the research and development teams of Suzuki. Technical features include roller bearing camshafts, two-piece spring dampened bevel silent primary drive gears, dual squish combustion chambers. It utilizes a DOHC eight-valve engine configuration. Twin downdraft Mikuni carburetors were standard until 2008, when fuel injection became available.[3] Cycle World tested the GT250R's acceleration at 0 to 97 km/h (0 to 60 mph) in 7.6 seconds and 0.0 to 0.4 km (0 to 14 mi) in 16.06 seconds at 128.89 km/h (80.09 mph).[1]

Fuel economy[edit]

The GT250R's recorded fuel consumption is 3.4 L/100 km (83 mpg‑imp; 69 mpg‑US) in comparison to 4.59 L/100 km (61.5 mpg‑imp; 51.2 mpg‑US) recorded on the Kawasaki Ninja 250R.[3] This allows the GT250R 500 km (310 mi) range from its 17 l (3.7 imp gal; 4.5 US gal) fuel tank.[3] Motorcyclist and Cycle World recorded 3.8 L/100 km; 74 mpg‑imp (62 mpg‑US).[1][2]

Suspension and handling[edit]

Non-adjustable 41 mm inverted forks are combined with a twin-spar steel frame to provide improved handling. Stock suspension setting is firm, providing stability through corners.[citation needed] Although commonly found only in larger sized sport bikes, the Hyosung GT250R comes standard with a 300 mm front disc setup using twin-piston calipers. Rear brakes is a single 230 mm disc.

2010 model changes[edit]

An Australian press release revealed that the 2010 GT250R has been slightly restyled, the most noticeable change taking place on the rear LED stop/tail-lamp.[5]

Electronic fuel injection will be standard on all of Hyosung's 2010 GTxxx models.[6] Not only that it will also receive oil cooler as standard rather than air cooled.
