The full 2008 Suzuki GSF 650S Bandit spec sheet below covers every technical detail, from suspension travel to tyre sizes.

2008 GSF 650S Bandit - Pros & Cons

Strengths

Strong power output: With 57.4 kW @ 10500 rpm and 54 Nm @ 9500 rpm of torque on tap, the GSF 650S Bandit is no slouch for its class.
Large fuel range: A 20-litre tank means fewer stops on longer rides - a genuine plus for touring or a lengthy daily commute.

Considerations

Carburetor fuelling: Expect to spend more time keeping the carbs in tune, especially after long storage periods or a change in altitude.
Chain final drive upkeep: Budget time for routine chain maintenance - it's cheap to replace but needs consistent attention to avoid premature sprocket wear.

Wear Points & Servicing Notes

Heat management in traffic

Because the GSF 650S Bandit relies on airflow rather than a coolant jacket, expect noticeably more radiant heat at low speed and in traffic. It's inherent to air cooling, and ventilated gear largely offsets it.

Carburetor maintenance

Carburetors on the GSF 650S Bandit need periodic attention - pilot jets and float needles are the first parts to gum up after the bike sits, and the first thing to check if idle or throttle response degrades.

Brake disc and pad wear

Braking up front comes from 2 x 290 mm Discs, 2 piston calipers - solid stopping power, with disc and pad wear best checked on the same schedule as tyre changes.

Suspension condition on used examples

The GSF 650S Bandit's suspension runs 41mm Telescopic fork, preload fully adjustable at the front. The rear uses Link type, oil damped, mono-shock, spring pre-load 7-way adjustable, rebound damping 4-way adjustable. Fork-seal condition and rear linkage play are the two things worth checking before buying used.

Final drive maintenance

The GSF 650S Bandit uses chain final drive, which is cheap to replace but needs regular cleaning, lubrication and tension checks to get a full service life out of the sprockets.

Frame & chassis check

Built around a Double cradle, the GSF 650S Bandit's chassis is straightforward to inspect: look for corrosion, cracks or repair welds around stress points like the head-stock and swingarm mounts.

GSF 650S Bandit - Buying & Maintenance Guide

What to check before buying

Before handing over money for a used 2008 Suzuki GSF 650S Bandit, cover the fundamentals: service book and oil change history, chain and sprocket wear, and any sign of oil weeping around the casings. Cold-starting it yourself tells you a lot - a healthy GSF 650S Bandit should catch quickly and settle into a smooth idle.

Oil and filter changes

Nothing protects a GSF 650S Bandit's engine like disciplined oil changes - stay on the manufacturer's schedule (roughly every 6,000 km or annually). Match the viscosity grade to what the owner's manual specifies, not what's cheapest.

Carburetor upkeep

Deposits in the carbs are the usual culprit behind poor running on a stored GSF 650S Bandit - strip and clean the float bowls before the first start. Pilot jets clog first and get overlooked most, so make a point of checking them.
