Overview[edit | edit source]
Hyosung GD250R
The GD250 is a lightweight, nimble street bike allowing all riders
(beginners and experienced) to experience the true essence of sport
riding.
Features and benefits:
Z-suit system. (Switchable riding position to suit various lifestyles.) Super sports position - Focus on sports riding. - Excellent controllability.
Street sports position
- Focus on daily street riding.
- Excellent accessibility.
Layout (Mass centralization - to the center of gravity of vehicle) - Engine is located near in the steering head. - Fuel tank is located near in the COG. - Muffler is located below the swingarm pivot. - Electric equipment unit is located near in the steering head.
Frame
- X-5's steel tubular trellis frame is designed to connect directly
between the steering head and pivot. Its compact size reduces weight
while enhancing the rigidity of the frame.
- X-5 is equipped with a long 553mm swingarm coupled with the short
1340mm wheelbase.
These features combine to provide a dynamic steering characteristic
and constant movement of the suspension.
Muffler
- Silencer located below the swingarm pivot which improves mass
centralization.
Centralized muffler having optimized center of gravity gives X-5
more active handling.
Fuel tank - Fuel tank located near in the COG. which improves weight centralization. - Fuel tank is tilted toward swingarm pivot, the fuel always gathers around the center of gravity. This feature provides natural steering character by reducing the amount of front / rear weight transfer. - Fuel tank is made from plastic for weight reduction.
Brakes
- Front: Ø 300mm single disc, opposed 4 piston caliper.
- Rear: Ø 230mm single disc, opposed 2 piston caliper.
Suspension
- Front: Ø 37mm upside down telescopic fork (120mm travel)
- Rear: Dual side Aluminum Swing arm with Gas charged Hydraulic
shock absorber (Nonstep Preload adjustable)
- The monocross shock absorber is laterally mounted because this
solution frees up space to the centrally located fuel tank, allowing
perfectly symmetrical weight distribution. The lateral shock
absorber is pivoted directly on the swingarm.
Electric equipment unit box
- Electric equipment unit box is located at the top of the
cylinder head. It contains battery, ECU, relay, fuse, regulator,
sensor, etc.
- This unit construction improves maintainability while reducing
weight by shortening the harness and reducing the number of
brackets.
