The HHH X18 125cc Dirt Bike is an off-road model built for teen and adult riders who want manual control and larger wheel sizing. The bike uses a 125cc air-cooled 4-stroke single-cylinder engine paired with a 4-speed manual transmission with clutch lever. Starting is handled by electric start with kick start backup.
The X18 uses 17-inch front and 14-inch rear off-road tires, offering better stability than smaller youth bikes. Fuel tank capacity is 4.5 liters. Seat height measures 32 inches, suitable for riders ages 16 and up. The steel perimeter frame supports trail and recreational dirt riding.
The engine produces 8.3 HP at 7000 RPM with 6.63 ft-lb of torque at 5000 RPM. Top speed reaches up to 47 mph, with an adjustable speed limiter for rider control. Suspension includes non-adjustable inverted front forks and a rear suspension system designed for off-road use.
Braking uses front and rear hydraulic disc brakes with single-piston calipers. The bike includes a kickstand and lightweight steel construction. This model is off-road use only and not street legal.
The X18 ships 70% assembled inside a metal crate. Some assembly is required, and a certified technician is recommended for final setup and inspection. Warranty covers 30 days for replacement parts only. Labor, mechanic costs, and returns are not covered. Freight delivery includes lift gate service, residential delivery, shipping insurance, and delivery appointment scheduling. A working phone number is required for delivery coordination.
