First Impressions & Ride Summary

The Duke 125 presents a refined streetfighter package — the Bosch EMS with Ride-by-Wire and retuned fueling give a crisp, predictable throttle. It feels grown-up for the class: light, precise and eager to rev when asked.

The 6-speed gearbox and wet multi-disc clutch make city traffic effortless while allowing spirited bursts on open roads. The chassis balance and geometry make it an engaging little motorcycle that’s forgiving for newer riders yet enjoyable for experienced ones.

Design & Ergonomics

Maintaining the Duke family’s signature cues — angular tank, visible trellis frame and sharp graphics — the 125 looks compact yet purposeful. The split step-up seat and confident riding position provide control without being overly aggressive for daily use.

Seat height is quoted at 800 mm by the manufacturer (some sources list 822 mm) — pick a test-ride to confirm fit if you’re on the shorter side.

Engine & Performance

The 124.7 cc single-cylinder DOHC mill with Bosch EMS and Ride-by-Wire now makes 15 PS @ 9,250 rpm and 11.5 Nm @ 8,000 rpm. The engine is refined for its class and rewards revvy riding — midrange is usable, top-end slightly peaky but fun.

Clutch feel is light thanks to the wet multi-disc layout and the six-speed gearbox is slick for both commuter and sporty use. Vibration is well controlled across the usable range.

Handling & Chassis

The trellis steel frame with a bolt-on aluminium subframe combines rigidity and lightness; wheelbase of 1357 mm helps the Duke turn in quickly while remaining stable. WP APEX suspension (43 mm USD fork, 150 mm travel; WP APEX monoshock, 150 mm travel) gives a planted feel with good feedback.

Travel and damping favour a dynamic riding style while still smoothing out broken surfaces for city use. The chassis balance encourages confidence through corners and during quick direction changes.

Braking

Braking hardware is beefed-up: a 320 mm front disc with a four-piston radial caliper and a 240 mm rear disc with single-piston caliper provide confident stopping. Tyres are 17-inch alloys, 110/70-R17 front and 150/60-R17 rear.

ABS configuration varies by variant (single or dual channel) — the system is tuned to be unobtrusive while offering sensible intervention for everyday safety.

City & Highway Compatibility

City: the Duke 125 excels — light steering, compact footprint and eager throttle make it ideal for commuting. Manufacturer city economy is quoted at 46.92 kmpl, while real-world figures typically land at 35–40 kmpl depending on usage.

Highway: capable of short highway stints up to 120 km/h, but long-distance comfort is limited by windblast and ergonomic constraints compared to larger Dukes.
