KTM 125 Duke 2024 Review: Handling, Tech, And Range

The KTM 125 Duke continues to dominate the learner motorcycle segment with its aggressive styling, lightweight construction, and premium components. Designed for A1 licence holders, this 125cc single-cylinder machine delivers 15bhp while packing features typically found on larger bikes, making it an ideal choice for new riders seeking excitement without compromise.

Engine Performance and Power Delivery

At the heart of the 2024 KTM 125 Duke lies a refined 124.9cc liquid-cooled, four-valve SOHC single-cylinder engine. Updated with a new cylinder head and gearbox, it produces a maximum of 15bhp at 10,000rpm and 8.5lb/ft (11.5Nm) of torque at 7,750rpm, adhering strictly to A1 restrictions. This setup ensures smooth power throughout the rev range, with crisp low-speed acceleration that pulls eagerly from standstill.

Real-world testing reveals the engine’s punchy nature despite its displacement. Riders report quick revving and usable torque from low revs, allowing confident urban commuting and spirited backroad runs. However, top-end pull tapers off, with speeds maxing around 66-75mph depending on conditions and rider weight—sufficient for dual carriageways but not ideal for sustained highway cruising. Fuel efficiency hovers at 80-90mpg, supporting long rides on a single tank.

While Euro 5.2 compliance has slightly dulled peak performance compared to predecessors, the Duke remains engaging, with minimal vibrations even at high revs.

Chassis and Handling Excellence

Weighing just 154kg, the KTM 125 Duke feels nimble and planted, thanks to a 1,357mm wheelbase and Michelin Road 5 tyres on 17-inch wheels. The steel trellis frame, borrowed from larger Dukes, provides big-bike rigidity without excess weight.

WP suspension shines here: 43mm Apex forks offer 150mm travel upfront, paired with a preload-adjustable monoshock at the rear. This setup absorbs bumps effortlessly while maintaining composure in corners, encouraging higher corner speeds on twisty roads. Riders praise its mid-corner stability and quick steering, making it forgiving for novices yet rewarding for experienced pilots.

• Featherlight feel on twisties
• Stable at speed despite short gearing
• Responsive to rider inputs

Braking System: Safety Meets Power

Braking is a standout, with a massive 320mm front disc gripped by a ByBre four-piston radial caliper and a 240mm rear disc with a twin-piston setup. Bosch cornering ABS includes Supermoto mode to disable rear ABS for slides, a rare feature in 125cc bikes.

The system delivers progressive, powerful stops—two fingers suffice for hard braking, with ABS intervening smoothly on grippy surfaces. This confidence inspires aggressive riding while prioritizing safety.

Design and Ergonomics for Modern Riders

The Duke’s sharp, angular lines and compact dimensions mimic its 390 and 890 siblings, projecting premium appeal. Wide bars, a roomy seat, and neutral riding position suit riders from 5’6″ to 6’3″, with feet flat at stops for shorter pilots.

Ergonomics promote an upright stance for visibility in traffic, while the narrow tank aids manoeuvring at low speeds. Its ‘ready to pounce’ stance turns heads, blending streetfighter aggression with everyday usability.

Technology and Rider Aids

Despite its size, the 125 Duke brims with tech: a 5-inch TFT display with Bluetooth connectivity, track/supermoto modes, and optional Quickshifter+ for clutchless shifts. Cornering ABS and traction control (switchable) elevate it above rivals.

LED lighting, including a fang-like headlight, ensures visibility, while the digital dash offers clear readouts for speed, gear, and ride data.

Riding Experience: Urban to Backroads

In city traffic, the Duke’s light clutch and torquey low-end excel, zipping through gaps with ease. On A-roads, it thrives—short gearing keeps momentum, and suspension irons out imperfections.

Track testing highlights its poise: ~106km/h top speeds and frantic revving evoke larger Dukes. Limitations appear on motorways, where wind and power constrain cruising above 70mph.

Pros and Cons at a Glance

Who Should Buy the KTM 125 Duke?
