Suzuki GSX1400 (2001–2008) Review | Specs, Performance & Parts
The Suzuki GSX1400 is a legend among muscle bikes. Released in 2001, it was Suzuki’s response to the growing demand for naked street bikes with huge torque, retro styling, and rock-solid reliability. Over its production life until 2008, the GSX1400 built a loyal following thanks to its powerful engine, classic design, and the unmistakable feel of a true heavyweight roadster.
In this review, we’ll break down everything you need to know about the GSX1400—from engine performance and comfort to how it stacks up today as a modern classic. We’ll also include a detailed technical specifications table and recommend high-quality aftermarket parts to elevate your GSX1400 ownership experience.
Design and Character
The GSX1400 borrows cues from the universal Japanese motorcycle (UJM) era, featuring a no-nonsense design with a round headlamp, twin rear shocks, upright seating, and a massive engine sitting proudly in its steel cradle. The bike offers a muscular stance with a long wheelbase and broad fuel tank, giving it a commanding presence on the road.
Despite its size, the GSX1400 feels surprisingly agile thanks to its balanced geometry and wide handlebars. Whether you're cruising through town or stretching its legs on open roads, the bike maintains a refined yet brutish personality—always willing to deliver torque on demand.
Engine and Performance
At the heart of the GSX1400 is a 1402cc air/oil-cooled inline-four engine with dual overhead cams and fuel injection. It produces around 106 horsepower and a whopping 125Nm of torque, with most of it available low in the rev range. This makes for an effortless and satisfying ride, especially in urban settings and spirited backroad journeys.
Unlike high-revving sportbikes, the GSX1400 shines with its torque-rich delivery. It surges forward with minimal throttle input and rarely needs to be revved hard. The five-speed gearbox is solid and smooth, and the clutch is light considering the engine size.

Ride Comfort and Handling

The upright seating position, wide bars, and plush saddle make it ideal for long rides. Two-up touring is a breeze, thanks to a supportive pillion seat and smooth throttle delivery.
Cornering stability is excellent for a bike of this size. It isn’t a canyon carver like a sportbike, but it holds its line well and responds predictably to steering input. Braking performance is solid, with the six-piston front calipers offering ample stopping power—especially when paired with performance pads from modern upgrades.
Build Quality and Longevity
One of the GSX1400’s most praised attributes is its durability. The engine is known to be bulletproof with proper maintenance. Build quality is excellent, with solid switchgear, minimal plastic, and quality paintwork that holds up over decades.
Many owners report exceeding 100,000 kilometers with minimal issues, making it a smart choice for riders who value reliability and classic Japanese engineering.
Customization Potential
The GSX1400 has become a cult classic in the custom scene. Its bare-bones, mechanical design lends itself well to personalization. From carbon fiber parts to performance brakes and premium fasteners, the aftermarket scene is thriving.
