HHH 125cc Go Kart GKT125-9 Spyder | Electric Start | 3-Speed Chain Drive
$1749 The HHH GKT125-9 Spyder 125cc Go Kart is a gas-powered off-road go kart built for recreational riding and controlled environments. It features a 125cc single-cylinder, air-cooled, 4-stroke engine paired with a chain-driven rear wheel system.
The engine produces 5.3 kW at 7500 rpm and 8.0 Nm of torque at 5500 rpm, delivering smooth and manageable power. An electric start system with CDI ignition allows easy starting. The engine uses pressure splash lubrication and runs on 87-octane or higher fuel.
This model includes a steel tube frame, hydraulic disc brakes, and a rear axle parking brake with hand control. Large 16×8-7 tires with iron rims improve traction and stability. A larger seat adds comfort during longer rides.
The go kart ships 70% assembled inside a metal crate. Final assembly and prep must be completed by a certified technician.

Bought this for my 9-year-old and he's obsessed. The adjustable speed limiter let me start him slow then open it up as he got confident. Arrived crated and well-packed.
Was nervous ordering a $1,200 ATV online but their phone support walked me through everything. Shipping was free and showed up in 5 days. Runs great.
