Zontes ZT 125 GK

Call it a sportscafe, call it a modern street scrambler…we call it the little brother of the GK350 and this is one serious 125cc motorcycle. Boasting big bike looks, with style to spare, this model showcases the very best of Zontes production, delivering a bike perfect for the modern world.

Gen 2.5 Keyless Control System

With advanced encryption technology, the Gen 2.5 Keyless Control System performs well in anti-theft protection. The induction key fob is both delicate and exquisite in design. The fobs activate and lock the system from a range of 1.5m, so can be kept in a pocket or backpack with no need to remove them, so avoiding the hassle of using a key to unlock the motorcycle. The system is both convenient to use and secure. The Gen 2.5 Keyless Control System is IP67 waterproof, and equipped with a built-in HF antenna, enhancing the sensitivity of the system. It also has a built-in chip sensor, enabling it to unlock the motorcycle even if its battery is removed or dead. This is only recommended for dead battery scenarios, not everyday operation.

GK125 Aluminum Alloy Rear Swing Arm

Aluminum Alloy Rear Swing Arm

Cast at the in-house foundry of Zontes Motorcycles and then processed through the very latest CNC machines, the aluminium alloy swing arm sets this motorcycle apart from the crowd. Through the combination of material and casting technology, the flexibility of aluminum alloy is close to that of steel tube. The material used is very difficult to break under both sheer and torsion loads. The characteristics of aluminum alloy, being lightweight and having good rigidity are brought into full play.

Ergonomic Shaped Seat Cushion

Zontes’ unique automatic cushion production line uses unique anti-foaming sponge forming technology. The result is a soft sponge which fits tight with the cover, and a sponge that does not flake or deform. The one-piece seat cushion is comfortable for long rides, yet full of retro style.

GK125 LED Lighting

LED Lighting

Automotive grade LED lights projected from an Auto-level LED light source is used, with a natural and soft colour temperature. The aluminum alloy die-casting headlamp rear shell significantly improves heat dissipation efficiency, to achieve a brighter illumination field, smaller light decay and longer service life. Bright LED tail-light, stop light and indicators, ensure other road users see you and note your intentions, improving rider safety.

Zontes ZT125-U Monn Shock Spring

Centre Mount Mono Shock

A centrally mounted mono shock softens the ride he center-mount rear mono-shock absorber utilises a high-pressure nitrogen cylinder, oversized piston, and high specification internals, so as to respond quickly, effectively absorb vibration caused by small bumps in the road and provides stronger support on rough roads. It is set with a small amount of preload and large rear wheel stroke, improving riding comfort and avoiding fatigue during long rides.

Cool touch stainless exhaust

Zontes ZT125-U 125cc Engine

High Compression Ratio Water-Cooled Motor

Running a high compression ratio of 12.5:1, the engine delivers 10.8kW @9000rpm. This puts the engine output and bike performance just within the limits of L Plate use in the UK. Another important feature of a high compression engine is low fuel consumption, an increasingly relevant feature in today’s World.

To achieve this Zontes utilise the latest materials and technologies available to design a class beating engine.

GK125 Large Radiator

Large Radiator

The large forward-facing radiator ensures effective airflow to allow the bike to operate at high speed under high load without fear of temperatures soaring. Equipped with 140mm diameter self-suction radiator fan, it provides ample heat dissipation effect to respond to climbing temperature during low-speed riding.

Zontes ZT125-U Clutch Mechanism

Slipper Clutch

Often seen in larger capacity, high performance models, Zontes introduce a slipper clutch to their latest 125cc models. The movement feels lighter in the hand and if a gear change is mis-timed so as engine and road speed differ hugely, the slipper clutch softens the blow. Unintentional wheel lock ups are avoided, mechanical shock lessened, and rider comfort and safety enhanced.
