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

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 1⁄4 mi) in 16.06 seconds at 128.89 km/h (80.09 mph).[1]

Fuel economy

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

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. 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

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]
