Suzuki GSX 750 (1983–1988) Review: The ’80s Icon That Still Thrills

Introduction

The 1980s were a golden age for motorcycling, and the Suzuki GSX 750 stands as a testament to an era when raw mechanical character and straightforward engineering ruled the roads. Produced from 1983 to 1988, this air-cooled inline-four became a benchmark for riders seeking reliability, versatility, and that unmistakable ’80s sportbike charm. Even decades later, the GSX 750 remains a favorite among enthusiasts who appreciate its no-nonsense approach to performance. Let’s dive into what makes this machine tick—and why it still deserves a spot in your garage.

Design & Styling: Retro Cool with Purpose

The GSX 750’s design screams ’80s muscle. Its boxy fuel tank, angular side panels, and dual round headlights give it a timeless, aggressive stance. The 800 mm (31.5-inch) seat height accommodates most riders comfortably, though the 236 kg (520 lb) wet weight reminds you this isn’t a featherweight modern sportbike. Still, the layout feels purposeful—every line and curve serves a function.

The air-cooled 747cc engine is the centerpiece, with its fins glinting under sunlight and headers sweeping back to a chrome exhaust. Unlike today’s liquid-cooled engines, the GSX’s simplicity is its virtue. The 37 mm telescopic forks (“TeleGabel” in German specs) and twin shock rear suspension hint at its dual nature: capable of carving corners but forgiving enough for daily commutes.

Performance: The Heart of a Workhorse

Engine & Power Delivery

The GSX 750’s 747cc inline-four produces 86 PS (63 kW) at the crank—about 85 horsepower by today’s standards. It’s not explosive by modern terms, but the power curve is deliciously linear. Throttle response from its carburetors (pre-set air screws for minimal fuss) is crisp, with a satisfying growl as revs climb past 6,000 RPM.

The real magic happens in the midrange. From 4,000 to 9,000 RPM, the GSX pulls with a steady surge, making overtaking or highway cruising effortless. The 14/43 sprocket combo and 114-link chain prioritize acceleration over top speed, though it’ll still nudge 210 km/h (130 mph) if you’re brave enough.

Riding Experience

Fire up the engine, and the idle settles at 1,100–1,200 RPM with a throaty burble. The vibration is noticeable but never intrusive—a reminder you’re riding a machine, not a computer. The cable-operated clutch is heavier than modern hydraulic setups, but engagement is predictable.

In city traffic, the GSX feels bulky compared to lighter nakeds, but the upright riding position and wide bars offer good control. On open roads, it transforms. The engine’s torque lets you short-shift lazily, while the chassis encourages spirited cornering. Just don’t expect razor-sharp agility; this bike prefers sweeping curves to tight switchbacks.

Handling & Braking: Confidence in the Corners

The GSX 750’s handling is a study in balance. The 37 mm forks and rear shocks soak up bumps admirably, though they can feel soft when pushed hard. Tire pressure is critical—Suzuki recommended 2.0 bar (29 psi) front and 2.5 bar (36 psi) rear for solo riding, which keeps the stock Bridgestones or Metzellers planted.

Braking duties fall to dual-piston calipers up front and a single rear drum. The setup lacks the bite of modern discs, but progressive lever feedback inspires confidence. Upgrading to sintered pads (available at MOTOPARTS.store) is a wise move for sharper stopping power.

Competition: How the GSX 750 Stacks Up

In the ’80s, the GSX 750 faced fierce rivals:

1. Kawasaki GPZ750: Liquid-cooled and tech-forward, the GPZ had a slight edge in top speed. However, its complex cooling system meant higher maintenance costs—a win for the air-cooled GSX’s simplicity.
2. Honda CB750: Smoother and quieter, the CB750 catered to touring riders. But Honda’s softer suspension and muted exhaust note couldn’t match the GSX’s sporty character.
3. Yamaha FJ1100: A powerhouse with 100+ horsepower, the FJ1100 dominated straight-line speed. Yet its heft and thirst for premium fuel made the GSX a more practical daily rider.

The GSX 750’s sweet spot? Blending sporty performance with everyday usability. It’s less finicky than the GPZ, more engaging than the CB, and far more affordable to run than the FJ.

Maintenance: Keeping the Legend Alive

The GSX 750’s air-cooled engine is famously durable, but proper care ensures longevity:

• Oil Changes: Use 3.8 liters of SAE 10W-40 oil (with filter). Regular intervals every 5,000 km (3,100 miles) are crucial.
• Spark Plugs: NGK DR8ES-L (standard) or DR8EIX (iridium upgrade) at 0.7 mm gap. Iridiums last longer and improve cold starts.
• Chain Care: The 114-link chain needs frequent lubrication. A DID X-ring chain from MOTOPARTS.store reduces maintenance hassle.
• Brake Fluid: Flush with DOT 4 annually to prevent spongy lever feel.
• Valve Adjustments: Check every 15,000 km (9,300 miles). The shim-under-bucket system isn’t beginner-friendly, but it’s rock-solid once set.

Pro Tip: Upgrade to a K&N air filter and aftermarket exhaust (we recommend Delkevic’s stainless system) to unlock a richer exhaust note and slight power gains.
