• Professionally restored by Jap Retro circa five years ago
• Only some 200 miles since completion
• Stored as part of a private collection
Suzuki rewrote the 750-class rulebook when it launched the GSX-R750 back in 1985. The Gixxer's development had been heavily influenced by lessons learned from the works TT F1 and Endurance racers; lighter than a 600 and as powerful as a 1000, it made all other super-sports 750s seem flabby and slow.
Like its predecessor, this new-for-1988 second generation GSX-R benefited from experience gained in racing, featuring a much stiffer frame and swinging arm; larger-diameter forks; larger front brakes; 4-pot brake callipers; 17" wheels; and a more aerodynamically efficient fairing. The engine had a shorter stoke; bigger valves; larger oil radiator; 4-into-2 exhaust system; and 36mm flat-slide 'Slingshot' carburettors that gave the model its nickname.
One of the modern era's few instant classics, the GSX-R750 has been a huge commercial success for Suzuki and enjoys cult status today. Now more than 30 years old, many early GSX-Rs have suffered at the hands of successive owners, a state of affairs that has resulted in well preserved examples becoming increasingly sought after by collectors.
A UK market example, this GSX-R750 Slingshot has been professionally restored (engine excepted) by Jap Retro, with everything done that was required. The following works were carried out:
Frame and cycle parts, blasted and powder-coated
Wheels, blasted and powder-coated; new bearings and tyres
Tank and bodywork stripped/blasted and repainted with new decals
Engine fully serviced and refreshed; paint stripped/cleaned and repainted
Carburettors stripped cleaned and rebuilt with new kits
Braking system fully stripped/cleaned, repainted and rebuilt with new kits and HEL brake lines
All bearings and cables replaced
The machine has only covered some 200 miles following the rebuild's completion approximately five years ago, since when it has been stored as part of the vendor's private collection (the current odometer reading is 39,959 miles). The vendor reports that engine pulls strongly with no issues. The restoration is fully documented by images on a memory stick, which prospective purchasers may view on request. There is also a video of the machine running, available to view on the Bonhams website. Included in the sale is a rear cowl, pillion seat and grab rail. Accompanying documents include a V5C, two MoT certificates (most recent expired 2019) and a 2015 R.A.P. Superbikes sales receipt, while it should be noted that the HPI report records the previous colour as black/grey. Four keys present.
