The Hyosung V-twin 250cc engine was designed in Hamamatsu Japan by a design team consisting of engineers who have previously worked in the R&D teams of some of the big Japanese motorcycle companies. Because this engine is the newest design among its rivals, it has many performance features that they do not have. These include roller bearing cam shafts, 2 piece spring dampened bevel silent primary drive gears, dual squelsh combustion chambers etc. These are features that were previously confined to racing engines, and in the past have been uneconomical for other manufacturers to incorporate into smaller capacity engines for street use. Proven DOHC 4 valve per cylinder configuration, with twin downdraft Mikuni carburetors provide the highest volumetric efficiency and air cooling coupled with an oil cooler provide reliability in the harshest conditions.

The latest sport bike styling is incorporated into a practical design. Note the pillion seat and heavy duty tie down rails for all your gear for those long trips. The rider's seat is firm in design to provide good support and reduce fatigue. Heavy duty rear disc brakes with twin piston fully floating caliper, six spoke alloy wheels with wide tubeless tires and free flowing exhaust system are used to give maximum performance. A low cost racing muffler is also available if additional engine output is required.

The comet series all incorporate key lock storage compartment under the pillion seat. Items such as wet weather gear, maps, lunch etc can be stored here, as well as locking helmet security (depending on helmet design). Tools are shown here to demonstrate size of storage however a purpose made tool storage slot is under the rider's seat. One key operates ignition, under seat storage and steering lock. GT250 comet comes in 4 color choices 1) mango yellow 2) signal red 3) midnight black 4) metallic sky blue.

The comet 250 comes standard with huge front disc brake with twin piston fully floating caliper. A twin disc kit is available as an option for racing use. A six spoke alloy wheel and tubeless tire are suspended by High tensile upside down forks which have been tuned in Australia by grand prix specialists to give optimum street performance with plush, sensitive response and race worthy performance.

With all this performance equipment, a new headlamp needed to be designed so the comet could be ridden to its full capability at night. The unique multi focus headlamp was designed in late 2002 to provide long distance light projection for the rider to see as far ahead as possible. It is the latest in headlamp design technology and is fitted with a shatter resistant lens and a H4 60/55watt globe
