Stomp FXJ 110 Manual Pit Bike

Stomp FXJ 110 Manual Pit Bike

110CC 4-STROKE. 4-SPEED MANUAL. FULL CLUTCH CONTROL. 14”/12” WHEELS. 🏁🔥

The Stomp FXJ 110 Manual is built for riders who are ready to move beyond semi-automatic bikes and learn the proper way to ride a manual motorcycle.

Powered by a 106.7cc YX110 4-stroke engine, the FXJ combines a 4-speed manual gearbox with a wet multi-plate clutch, giving the rider complete control over the engine and gearing.

With 14” front / 12” rear wheels, hydraulic disc brakes, oil-filled front forks and an adjustable rear shock, the FXJ is a proper little pit bike rather than a toy dressed up to look like one.

It’s compact, simple and built around learning, improving and having fun off-road.

🔥 106.7cc YX110 4-Stroke Engine

At the heart of the FXJ is the proven YX110 4-stroke engine, with a displacement of 106.7cc.

CMW lists maximum output at:

5.1kW @ 8,000rpm

and maximum torque at:

7.2Nm @ 5,000rpm

The engine is air-cooled and uses a 19mm Nibbi carburettor, keeping the mechanical package straightforward and easy to maintain. 

⚙️ 4-Speed Manual Gearbox

This is where the FXJ really differs from the automatic and semi-automatic bikes.

The FXJ uses a proper 4-speed manual gearbox:

N → 1 → 2 → 3 → 4

The rider controls the gears using the foot lever and operates the wet 3-disc clutch from the handlebar.

That makes the FXJ an excellent bike for riders wanting to learn proper clutch control, gear changes and engine management.

🕹️ Learn Proper Clutch Control

If a rider has already mastered an automatic or semi-automatic bike, the FXJ gives them the next challenge.

They’ll learn how to:

• Pull the clutch in
• Select the correct gear
• Find the biting point
• Feed the throttle in smoothly
• Change up through the gears
• Downshift when required
• Control the bike using engine braking

It keeps the learning experience much closer to riding a full-size manual motorcycle.

🔑 Traditional Kick Start

The FXJ uses a kick-start system, keeping the bike mechanically simple.

There’s no electric starter system to rely on, giving the FXJ that traditional pit-bike character.

The ignition system uses CDI, with the 4-stroke engine designed around straightforward maintenance. 

💥 Oil-Filled Front Forks

The front suspension uses 630mm conventional oil-filled forks.

They’re held by strong steel triple clamps and are designed to cope with the bumps and uneven surfaces encountered during suitable off-road riding.

🔧 Adjustable Rear Shock

At the rear is a 270mm shock with adjustable preload.

The preload adjustment allows the rear suspension to be set up according to rider weight and riding conditions.

The FXJ also uses a 390mm steel swingarm, giving the compact pit-bike chassis a solid platform. 

🛑 Hydraulic Disc Brakes

The FXJ comes equipped with hydraulic disc brakes front and rear.

Front

190mm hydraulic disc

Rear

180mm hydraulic disc

This gives the rider dedicated hydraulic braking at both ends of the bike.

As always, brakes should be checked before riding and maintained regularly. 

🛞 14”/12” Pit Bike Wheels

The FXJ uses the classic 14” front / 12” rear pit-bike wheel combination.

Front

60/100-14

Rear

80/100-12

This keeps the overall bike compact while providing the ground clearance and riding position you’d expect from a proper pit bike.

🏗️ Lightweight Steel Spine Frame

The FXJ is built around a lightweight steel spine frame.

Combined with the 390mm steel swingarm and approximately 60kg dry weight, the compact chassis is designed to keep the bike manageable and playful.

It’s small enough to be approachable while still providing a proper manual motorcycle riding experience.

📏 Compact Pit Bike Dimensions

The FXJ has an approximate:

Seat height: 740mm
Ground clearance: 275mm
Wheelbase: 1,085mm
Dry weight: 60kg
Fuel capacity: 3.5L

The 740mm seat height makes rider fit particularly important, especially for younger riders progressing into manual bikes. 

👤 Is The Stomp FXJ 110 Right For You?

The FXJ is a great choice for riders who want to learn manual riding properly without jumping straight onto a much larger machine.

Want something easier to ride?

The BRZ 70cc Automatic keeps things simple with a fully automatic transmission.

Want to learn gears without a manual clutch?

The BRZ 110cc Semi-Automatic allows the rider to change through the gears without operating a clutch.

Want a compact manual bike?

That’s where the Stomp FXJ 110 Manual fits perfectly.

Want more performance and a larger chassis?

The Stomp Z3-140 Big Wheel moves into a much more performance-focused 140cc platform with 17”/14” wheels.

For riders looking for even more engine capacity, we also stock 160cc and 250cc manual pit bikes.
