Kayo A150 EFI Kids Petrol Quad Bike 2026

The Kayo A150 EFI is a substantial step up in the petrol quad range, combining fuel injection, a larger chassis and a two-speed transmission with reverse.

Why Choose the Kayo A150 EFI?

The Kayo A150 EFI is designed for riders who need more room and capability than a smaller youth quad provides. Its 137.3cc four-stroke engine, 715mm seat height and 1,045mm wheelbase give it a noticeably larger platform than the entry-level Kayo models.

Electric starting, a two-speed semi-automatic transmission and reverse make the A150 practical to operate, while hydraulic disc brakes and a safety lanyard provide equipment suited to supervised off-road riding.

137.3cc Fuel-Injected Four-Stroke Engine

The A150 EFI uses an air-cooled, SOHC two-valve engine with electronic fuel injection.

• Engine displacement — 137.3cc
• Maximum power — 7.5kW at 7,500rpm
• Maximum torque — 10.5Nm at 5,500rpm
• Starting system — Electric
• Fuel capacity — 4.5 litres

Fuel injection removes the need for a conventional carburettor and is a key difference between the A150 EFI and smaller petrol quads in the range.

Two Speeds and Reverse

The semi-automatic transmission provides two forward speeds and reverse. Riders can select between reverse, neutral, first and second gear without operating a hand clutch.

• Transmission — Semi-automatic, R–N–1–2
• Clutch — Wet clutch
• Final drive — 2WD chain drive

Reverse is particularly useful when manoeuvring a quad of this size in a confined space.

Larger Chassis and Suspension

With a 1,045mm wheelbase and 715mm seat height, the A150 offers more space for a growing rider than Kayo’s smaller petrol quads.

• Vehicle size — 1,540 × 965 × 970mm
• Wheelbase — 1,045mm
• Seat height — 715mm
• Ground clearance — 120mm
• Dry weight — 135.5kg
• Front tyres — 10-inch
• Rear tyres — 9-inch

The front and rear suspension are non-adjustable. The larger chassis should be considered carefully when assessing whether the rider can comfortably reach the controls and manage the quad.

Braking and Safety Equipment

Hydraulic disc brakes are fitted at both ends. The A150 also includes a safety lanyard, rear parking brake, headlights and taillights.

• Front brake — Hydraulic disc
• Rear brake — Hydraulic disc
• Parking brake — Rear
• Safety lanyard — Fitted
• Lights — Headlights and taillights

The safety lanyard is designed to stop the engine if the rider becomes separated from the quad.

Who Is the Kayo A150 EFI For?

The A150 EFI is best considered for a developing rider who has outgrown a smaller petrol quad and can confidently manage its size, weight, controls and power. Fit and riding experience matter more than age alone.

If the rider needs a smaller step, compare the A150 with the Kayo A110. You can also browse our full quad range to compare petrol and electric options.
