Hyosung GT125 & GT250 Series Resources
The Hyosung GT series is the most popular range in the lineup, spanning the naked GT125/250 Comet, the faired GT125R/250R, and the modern RC/P facelifts. As these bikes are very common across the UK and EU, we have preserved these official workshop manuals and owners books to ensure access for the community.
Model Identification & Technical Data
Whether you are tuning carburettors on a Gen 1 silver-engine model or diagnosing a Delphi EFI system on a newer black-engine 250cc, identifying your generation is key:
- GT125/250 (1998–2008): Silver engine, Mikuni Carbs, “Old Shape” (Gen 1).
- GT125/250 RC & P (2009+): Black engine, Facelifted bodywork, Carburetted or EFI.
- EFI Models (2008+): Features an O2 sensor in the exhaust downpipe and 28hp DOHC V-Twin engines.
- Maintenance: All models feature the iconic 75° V-Twin DOHC 8-valve architecture.
For more details, see our Pre-2009 (Gen 1) Wiki or the Post-2009 Facelift Gallery.
Carburetted (Carby) Models
