The K6 is the one a lot of riders still rate as the best GSX-R750 Suzuki ever built. 148bhp from the 750cc inline four, a chassis light enough to flick between corners like a 600, and a mid-range that pulls properly from 6,000rpm. It is the bike that made the 750 class famous, and two decades on it still does everything a modern litre bike does on a British B road, just with more feel and less electronics getting in the way.
This one has been genuinely cherished. The service book is stamped from the very first 600 mile service at a Suzuki main dealer and the file that comes with it holds the original Suzuki pre-delivery inspection sheet, loose invoices covering almost every job the bike has had since and the last service was carried out in November 2025. Paperwork like this on a 2006 sports bike is rare.
The previous owner has spent serious money on carbon. Front mudguard, fork guards, tank cover, tank infill panels, rear hugger and chain guard are all carbon, along with a carbon fuel cap cover. There is a Lextek slip-on with a carbon end cap, a full set of GB Racing engine case protectors on both sides, an aftermarket top yoke, adjustable short levers, red Domino grips and an SW-Motech quick-lock tank ring for a tank bag.
Finished in black with the red and white GSX-R graphics, and it presents beautifully for the year. Two original keys are present. If you have been waiting for a well-kept, honest K6 with the history to back it up, this is the one to come and see.|| At Superbike Specialists, we offer a top selection of HPI-clear used motorcycles (unless stated).
