    RFN Warrior SX-E700 R MX Edition – Quick Overview

    Best for: confident young riders aged around 5–9 years old.

    Recommended rider height: approximately 110–130cm.

    Motor: 36V 500W brushless motor, 700W peak.

    Seat height: 490mm.

    Speed settings: 9.5mph / 15.5mph / 21.5mph.

    Part of: RFN Warrior Kids range.

    Our view: the most powerful RFN Warrior Kids model, built for confident riders who want maximum off-road performance before stepping into larger RFN bikes.

    The RFN Warrior SX-E700 R MX Edition sits at the top of the RFN Warrior Kids range, delivering more power, more battery capacity and more off-road capability than the SX-E400 and SX-E500.

    Built for confident young riders, it combines a 700W peak brushless motor, larger 36V 7.4Ah battery, upgraded suspension, hydraulic brakes and a serious mini motocross feel.

    The SX-E700 sits above the SX-E400 and SX-E500 in the RFN Warrior Kids range. If your rider is already confident and ready for more performance, this is the strongest Kids-range option.

    If you're comparing models, read our SX-E500 vs SX-E700 MX guide, our SX-E700 MX vs SX-E700 SM comparison, or our full RFN Warrior Kids Range Explained.

    My Take as a British MX Rider

    The SX-E700 R MX Edition is the most serious Warrior Kids option for younger riders.

    Compared with the SX-E400 and SX-E500, the extra power, bigger battery and upgraded chassis parts make it feel much more planted and capable off-road.

    If your rider is already confident and you want the highest-performance RFN Warrior in this size range, the SX-E700 R MX is the one to look at.

    Why Choose the RFN Warrior SX-E700 R MX Edition?

    Top Warrior Kids Model

    The most powerful and capable RFN Warrior Kids bike for confident younger riders.

    700W Peak Output

    More acceleration and performance than the SX-E400 and SX-E500 models.

    Bigger Battery

    36V 7.4Ah lithium battery for improved ride time and more demanding sessions.

    Upgraded Chassis

    Fast Ace rear shock, hydraulic brakes and heavy-duty CNC footrests.

    Built for Confident Young Riders

    Best for Ages 5–9

    The RFN Warrior SX-E700 R MX Edition is designed for confident riders aged around 5–9, approximately 110–130cm tall.

    With a 490mm seat height, 20kg weight and maximum rider weight of 50kg, it is best suited to riders who are already comfortable on two wheels and ready for more speed, control and off-road capability.

    Suitability always depends on the individual child’s height, weight and skill level — at the parent’s discretion.

    Speed Settings

    Mode Speed Best For
    Eco 9.5mph Controlled confidence-building
    Low 15.5mph Stronger mid-range performance
    Sport 21.5mph Experienced riders using full performance

    More Power and Bigger Battery

    The SX-E700 R steps up to a 500W brushless motor with 700W peak output, delivering noticeably stronger acceleration than the SX-E400 and SX-E500.

    Maximum Warrior Kids Performance

    • 36V 500W brushless motor
    • 700W peak output
    • 36V 7.4Ah lithium battery
    • Up to 11.5 miles range
    • Around 75 minutes ride time
    • Removable battery for easy swapping

    This makes the SX-E700 R better suited to longer sessions and more demanding riding.

    Upgraded Suspension, Brakes and Handling

    The R MX Edition brings meaningful upgrades across the chassis, giving it a more planted, stable and capable ride across dirt, grass, trails and mixed terrain.

    MX Edition Chassis Upgrades

    • Front suspension forks
    • Fast Ace adjustable rear shock
    • 140mm hydraulic disc brakes front and rear
    • Heavy-duty CNC alloy footrests
    • 14 x 2.4 inch all-terrain tyres
    • Steel frame for real off-road use

    The larger stance, upgraded suspension and improved braking give the SX-E700 R a noticeably more capable feel than lower Warrior models.

    MX Edition vs SM Edition

    The SX-E700 MX version is designed for off-road riding, including fields, grass, tracks, dirt and private land. It uses an off-road tyre setup for better grip on loose and uneven surfaces.

    The SX-E700 SM version is better suited to tarmac, hard-packed surfaces and supermoto-style riding.

    Most UK riders should choose the MX version unless most riding will be on tarmac or kart-track style surfaces. Read our SX-E700 MX vs SX-E700 SM guide.

    Battery, Range and Charging

    Battery Charge Time Range / Ride Time
    36V 7.4Ah lithium Approx. 2–3 hours Up to 11.5 miles / around 75 minutes

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
5 to 6Ages 5 to 637cm55cm
6 to 7Ages 6 to 739cm57cm
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 36.5cm11.5cm
4 to 5Ages 4 to 57cm12cm
6 to 7Ages 6 to 77.5cm12.5cm
YS, Youth SmallYouth Small8cm13.5cm
YM, Youth MediumYouth Medium8.5cm14cm

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.
