The 2026 Benelli BKX 125 S is a road-focused 125cc motorcycle designed for riders who want agile handling, distinctive styling and everyday versatility. As the road version of the BKX family, it combines a 125cc Euro 5+ liquid-cooled engine with a steel trellis frame, 17-inch alloy wheels and fully adjustable suspension.

With 15hp, a six-speed gearbox, ABS braking, full LED lighting and an 820mm seat height, the BKX 125 S is designed for city riding, commuting and enjoying twisty roads. Its 142kg weight and 1,390mm wheelbase also contribute to its easy handling and quick changes of direction. 

125cc Euro 5+ Engine

The Benelli BKX 125 S is powered by a 125cc, single-cylinder, four-stroke, four-valve liquid-cooled engine producing 15hp (11kW) at 9,500rpm and 12.1Nm of torque at 7,000rpm.

Electronic fuel injection and a six-speed gearbox provide responsive performance while keeping the engine within A1 licence power limits.

The engine uses forced wet-sump lubrication and features a catalytic converter with double oxygen sensors.

Fully Adjustable Suspension

The BKX 125 S features a 41mm upside-down front fork that can be adjusted for spring preload, compression and rebound.

At the rear, a progressive-link monoshock is adjustable for spring preload and rebound. Both front and rear suspension offer 150mm of travel.

This level of adjustability allows riders to tailor the chassis to their preferred riding style and conditions.

17-Inch Alloy Wheels

The BKX 125 S uses 17-inch aluminium alloy wheels with road-focused tyres.

A 100/80-17 tyre is fitted at the front and a 130/70-17 tyre at the rear, complementing the motorcycle's road-focused handling and sporty character.

ABS Braking

ABS is fitted as standard.

The front brake uses a 280mm floating disc with a four-piston calliper, while the rear features a 240mm disc with a single-piston floating calliper.

Full LED Lighting

The BKX 125 S features full LED lighting as standard.

The distinctive front LED lighting blades give the motorcycle a distinctive appearance, while the rear indicators incorporate integrated stop and position lights.

Handguards with Integrated Indicators

Handguards are fitted as standard and incorporate integrated LED indicators, combining practical protection around the controls with a clean front-end design.

12-Litre Fuel Tank

The BKX 125 S has a 12-litre fuel tank, including a 1.5-litre reserve.

Benelli states that the motorcycle can provide a range of around 500km, depending on riding conditions and riding style.

820mm Seat Height

The 820mm seat height provides an accessible riding position while retaining the upright character of the BKX 125 S.

Combined with a 142kg unladen weight and 1,390mm wheelbase, the motorcycle is designed to be easy to manoeuvre through city streets and responsive on winding roads.
