Suzuki GSX-S Suspension and Brakes
Suzuki GSX-S Suspension and Brakes, the suspension on the GSX-S1000 is very well specified and designed and the GSX-S750 Suspension nearly as good but both can be improved
At the front are 43mm KYB Inverted forks with a 120mm stroke, providing a sporty yet plush ride, The front forks are fully adjustable for preload and rebound and compression damping. Although the forks are good they are not perfect and can be upgraded by re-valving
At the rear a Link-type shock unit with a 63 mm stroke,The rear suspension is adjustable for rebound damping and spring preload. The rear shock is not particularly good being both harsh and suffering from a lack of control. There are various options for Upgrade
- Ohlins Single tube 360, basic Ohlins shock The STX 46 Street is based on our popular 46 mm shock absorber with divided piston and adjustable rebound damping, developed for naked sports bikes and street performance bikes. It features a large 46 mm main piston and an internal gas reservoir within the main body of the shock.
- replace with a shock from a GSXR1000, needs modifications made to the bike and is a little shorter
- replace with a shock from a Yamaha R1, is about 30mm shorter than stock, see here for install with adaptor
- replace with a shock from a Kawasaki ZX10R, is about 20mm shorter than stock
- Nitron, 3 versions from the basic R1 with combined damping adjustment to the sophisticated R3 with 3 damping adjustment
- Wilbers, 3 versions from preload only to 2 way damping
- Revalve, as far as i know, only Racetech do revalve kits for the standard shock
- Ohlins GSXR1000 TTX GP Shock, the best and the one I chose, but does need some modifications to fit
For information on setting up the GSX-S Suspension see this link.
The brakes are well specified with twin Brembo 4 pot calipers, 310mm discs and ABS is standard on most bikes, however as standard they don’t offer much bite so the first upgrade is usually to better pads such as EBC HH pads, but the bike also benefits from Braided hoses and a radial Master Cylinder
The suspension on the GSX-S750 is of a similar design to the GSX-S1000 but the damping is not adjustable – just the preload and the front end has 41mm KYB inverted forks
The brakes are of a similar design with 4 piston radial calipers, but made by nissin and with differently sized pistons and with wavy discs but only has a conventional 15mm master cylinder, see here for upgrade using the 19mm Radial master cylinder from the GSXS1000
