    A larger Kayo petrol quad for developing riders

    137.3cc fuel-injected four-stroke engine

    Two-speed semi-automatic transmission with reverse

    Hydraulic disc brakes, safety lanyard and rear parking brake

    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.

    For off-road use only; not suitable for use on public roads. Young riders must be supervised and wear appropriate protective equipment.

Revvi full-face helmet sizes

How to measure

Measure around the widest part of the rider's head. The tape should pass above the eyebrows and ears and around the fullest part at the back of the head.

SizeHead circumference
XS, Extra Small48 to 50cm
S, Small51 to 54cm
M, Medium55 to 58cm
L, Large59 to 61cm

Always choose by the rider's actual head measurement, not by age. Head shape can also affect how a helmet fits.

Between sizes? Do not automatically choose a larger helmet for growing room. A helmet must fit securely now. If the rider falls between sizes, check the fit carefully before use.

Amped AMP-1 helmet sizes

How to measure

Measure around the widest part of the rider's head. The tape should pass above the eyebrows and ears and around the fullest part at the back of the head.

SizeHead circumference
M, Medium54 to 58cm
L, Large58 to 62cm

Always choose by the rider's actual head measurement, not by age. Head shape can also affect how a helmet fits.

Measuring exactly 58cm? That falls in both sizes. Fit varies with head shape, so check the measurement and that the helmet sits securely before use. Do not choose a loose helmet to allow growing room.

Revvi riding jersey sizes

Choosing a size

The Revvi Kids Riding Jersey comes in dedicated sizes for younger children and growing youth riders. Select the size before adding it to your basket.

SizeAge guide
Age 2About 2 years
Age 3About 3 years
Age 4About 4 years
Age 5About 5 years
YS, Youth SmallAges 6 to 7
YM, Youth MediumAges 8 to 9
YL, Youth LargeAges 10 to 11

Ages are a guide only. Consider the child's height, build and preferred fit too.

Between sizes? If the rider is between sizes, still growing or likely to wear a base layer underneath, the larger size may be more comfortable.

Kids riding jersey sizes

How to measure

Compare these with a jersey or long-sleeve top that already fits the rider well. Chest width is measured across the front with the jersey laid flat, so it is half the full chest.

SizeAge guideHalf chestLength
2 to 3Ages 2 to 331cm49cm
3 to 4Ages 3 to 433cm51cm
4 to 5Ages 4 to 535cm53cm

YS, Youth SmallAges 7 to 941cm59cm
YM, Youth MediumAges 9 to 1145cm63cm
YL, Youth LargeAges 11 to 1449cm67cm

Ages are a guide only. The chest width and body length are the best way to choose.

Riding glove sizes

How to measure

Palm: straight across the widest part of the palm, not including the thumb.
Length: from the base of the wrist to the tip of the longest finger.

SizeAge guidePalm widthHand length
2 to 3Ages 2 to 37cm11.5cm
4 to 5Ages 4 to 57.5cm12.5cm
6 to 7Ages 6 to 78cm13.5cm
YS, Youth SmallAges 8 to 98.5cm15cm
YM, Youth MediumAges 10 to 119.5cm16.5cm
YL, Youth LargeAges 12 to 1310cm17.5cm
YXL, Youth Extra LargeAges 13+10.5cm18.5cm

Use the measurements rather than age alone. Hand shapes vary, so check both wherever possible. Once fitted, make sure the rider can comfortably use the throttle, brakes and every handlebar control.

Between sizes? The larger size usually gives a more comfortable fit and a little growing room, but the glove must not get in the way of safe control of the bike.
