- ―In game description
The GX300 is a vehicle featured in Sleeping Dogs.
It is a cruiser bike with 1990s design styling, seemingly based from the Suzuki GS550E cruiser bike with front light 'mask' accessories added. The GX300 is slightly faster than 270 DX cruiser bike (both are cruisers and both are Class B motorcycles), making it ideal for Hong Kong's twisty roads.
It is manufactured by the fictional company - Tomoshiba.
