Sun Coast Cycle Sports carries inspected used parts for the 2006-2007 Suzuki GSX-R600 (K6/K7) and GSX-R750 (K6/K7). This generation brought notable engine revisions including redesigned cylinder heads, revised cam timing, larger airbox volume, and electronically controlled exhaust valves (SET system) integrated more deeply into the engine management. The 750 gained titanium valves and produced approximately 150 horsepower, while the 600 delivered around 125 horsepower. The K6/K7 refined the aggressive styling introduced on the K4/K5 with a more flowing bodywork design and updated instrumentation. Sun Coast sources these parts from donor machines, with each component inspected by our powersports team, given a unique SKU, and shipped from Odessa, Florida.
06-07 GSXR600/750 generation and parts compatibility
| Model | Years | Engine | Key specifications |
|---|
| GSX-R600 K6 | 2006 | 599cc liquid-cooled I4 | Revised cylinder head, larger airbox, new bodywork, updated ECU |
| GSX-R600 K7 | 2007 | 599cc liquid-cooled I4 | Color/graphics update, mechanically identical to K6 |
| GSX-R750 K6 | 2006 | 749cc liquid-cooled I4 | Titanium valves, revised cam profiles, new bodywork |
| GSX-R750 K7 | 2007 | 749cc liquid-cooled I4 | Color/graphics update, mechanically identical to K6 |
The K6 and K7 within each displacement are mechanically identical, with all parts interchanging freely between the two model years. The GSX-R600 and GSX-R750 K6/K7 share the same frame, bodywork, wheels, brakes, suspension, and most chassis components. Fairings interchange between the 600 and 750. Engine internals differ between the two displacements (bore, stroke, pistons, cams, fuel injection mapping), but external engine mounting points and exhaust routing are compatible.
The K6/K7 does NOT share significant parts with the K4/K5 (2004-2005) it replaced. Bodywork dimensions, headlight design, instrument cluster, and internal engine specifications all changed. Similarly, the K8+ generation (2008-2010) was another revision with different bodywork and updated electronics. Each two-year GSX-R600/750 generation must be treated as a distinct platform when ordering parts. However, some deep internal engine components and certain brake system parts may cross between adjacent generations within the same displacement where part numbers overlap.
Common 06-07 GSXR600/750 failure points and replacement parts
Front brake master cylinder (NHTSA Campaign 13V449): Both the 2006-2007 GSX-R600 and GSX-R750 are included in the 210,228-unit brake recall. Corroded brake pistons combined with deteriorated fluid create gas that progressively reduces front brake pressure. Suzuki replaced the master cylinder with a redesigned unit. The reservoir hose exiting from the top of the master cylinder confirms the recall has been completed.
Regulator/rectifier failure: The K6/K7 uses the same basic shunt-type R/R as earlier generations, and it remains the most common electrical failure point. MOSFET aftermarket replacements are the recommended upgrade for reliable long-term charging.
SET valve servo sticking: The exhaust tuning valve servo motor is more deeply integrated on the K6/K7 than on earlier generations. When the servo sticks or fails, it triggers an FI warning light. Cold and damp conditions exacerbate the issue. Some owners report the valve sticking open after cold wet rides, causing snatchy low-speed fueling. Replacement servos, block-off kits, and eliminator wiring harnesses are all available solutions.
Cam chain tensioner: While the hydraulic CCT is improved over earlier generations, it can still develop top-end rattle at higher mileages. The issue is less common on K6/K7 models than on SRAD-era bikes but still worth monitoring. Aftermarket manual CCTs remain available as a preventive upgrade.
Instrument cluster LCD deterioration: Some K6/K7 owners report LCD segments fading or developing dead pixels over time, particularly on bikes that have been stored in direct sunlight. Replacement clusters from a same-generation donor are a direct swap.

Frequently asked questions
Q: Will K4/K5 or K8+ parts fit a K6/K7 GSX-R600 or 750
No for bodywork, headlights, and instrument cluster, which changed between each two-year generation. Some internal engine components within the same displacement may share part numbers across adjacent generations, but this must be verified on a part-by-part basis. Brake calipers, wheels, and fork assemblies may also cross between generations where specifications overlap, but always confirm fitment before ordering.
Q: Do 600 and 750 K6/K7 share the same bodywork
Yes. All fairing panels, tank, tail section, seat, and front fender interchange between the GSX-R600 and GSX-R750 K6/K7. The frame and bodywork mounting points are identical. This has been the case for every GSX-R600/750 generation since the SRAD and makes finding replacement body panels significantly easier.
Q: Is the K6/K7 GSX-R750 the same as the K6/K7 GSX-R1000
No. Despite sharing the "K6/K7" year designation, the GSX-R750 and GSX-R1000 are completely different motorcycles with different engines (749cc vs 998.6cc), different frames, and different bodywork. The 1000 is physically larger and uses a wider rear tire. There is no parts crossover between the 750 and 1000 in any generation. The K-codes simply denote model year, not a shared platform.
