The Zontes ZT125‑GK is the 125cc that refuses to behave like one. Inspired by the larger GK350, this compact sport‑café machine brings big‑bike attitude, premium engineering and modern urban style into the 125 class. From its aggressive stance to its high‑spec componentry, the GK is built for riders who want more than just a commuter — they want a statement.
Powered by a responsive 124.7cc water‑cooled engine, the GK delivers strong performance with impressive efficiency, supported by Bosch injection, a high compression ratio and a smooth 6‑speed gearbox with slipper clutch. Whether navigating city streets or stretching its legs on open roads, the GK feels planted, confident and surprisingly refined.
A high‑strength steel frame, 38mm USD forks and a centre‑mounted nitrogen rear shock give the bike excellent stability and comfort, while dual‑channel Bosch ABS and large disc brakes provide serious stopping power. Lightweight alloy rims, all‑terrain tyres and a 17‑litre galvanised tank complete a package built for real‑world riding.
Technology is where the GK really stands out. A Gen 2.5 keyless control system, digital LCD display, dual fast‑charging USB ports, LED lighting throughout and TPMS (Tyre Pressure Monitoring System) all come as standard — features rarely seen on bikes in this class.
From its forged aluminium hand guards to its cool‑touch stainless steel silencer, the ZT125‑GK is engineered with the same attention to detail as Zontes’ larger models. Stylish, capable and packed with premium equipment, it’s the perfect choice for new riders, commuters or anyone wanting a 125 that looks and feels like a much bigger machine.
