The engine has been upgraded and recently refreshed, now displacing approximately 1,085cc. It features a gas-flowed cylinder head with enlarged valves, Wiseco pistons and a strengthened clutch. An oil cooler has also been fitted to enhance reliability under race conditions. Engine work was carried out by Suzuki specialists Grumpy 1260 Racing.
The chassis has been upgraded to Yoshimura-type specification, including a braced original frame and a period Metmachex braced swinging arm. Suspension upgrades include GSX-R1100 front forks set up by K-Tech and longer YSS rear shock absorbers (originally intended for a CB900) to increase ground clearance. The machine runs GSX-R750 wheels and braking components.
Although built for racing, the Suzuki is road registered and currently classified under Historic Vehicle status, meaning it is exempt from road tax and MoT requirements. It remains usable on the road, though its race-focused setup makes it less suited to everyday riding. This motorcycle was raced and meticulously maintained over a four-year period and has since been kept in good order. It offers significantly improved handling over a standard GS1000S.
It should be noted that both the V5C and HPI report mistakenly omit a '0' from the GS1000 frame number prefix. The HPI report records a prior overseas registration, with the first UK registration dated 16/10/1996. The motorcycle has had five former keepers. Its current colour is listed on the HPI/V5C as silver (changed on 20/03/1998), having previously been red/white.
A highly developed and well-sorted period race replica, equally suited to classic racing events or parade use, with the added benefit of road registration.
