Description
10TEN JHL LX250R 21/19 Motocross Bike
The 10TEN JHL LX250R 21/19 is the motocross-focused machine in the new 10TEN JHL range, combining a full-size chassis with a claimed 42 hp YK250 engine, Bosch electronic fuel injection, adjustable KYB suspension and DID wheels.
Where the smaller models are built around accessible recreational riding, the LX250R takes a more performance-led approach. Its 21/19-inch motocross wheels, five-speed manual gearbox and 960mm seat height place it firmly in full-size off-road territory.
Premium components from recognised names including Bosch, KYB and DID help distinguish the LX250R from the more affordable trail and pit-bike models in the range.
42 HP YK250 Engine
The full-size engine produces a claimed maximum of 42 hp for closed-course off-road use.
Bosch EFI
Electronic fuel injection replaces the conventional carburettor used on the smaller models.
KYB Suspension
Adjustable KYB suspension allows the chassis to be tuned for the rider, track and conditions.
DID 21/19 Wheels
Full-size DID aluminium rims use the traditional 21-inch front and 19-inch rear motocross combination.
42 HP YK250 Engine
At the heart of the LX250R is the YK250 engine, producing a claimed maximum output of 42 hp for off-road use.
Power is delivered through a five-speed manual gearbox and conventional manual clutch, giving the rider direct control over gear selection and power delivery.
This is a considerable step up from the recreational pit bikes and trail-focused models in the range. The LX250R is intended for experienced riders who can confidently manage a full-size, high-performance motocross bike.
Electric start is fitted as standard and powered by a compact 12V 4Ah lithium battery.
Bosch Electronic Fuel Injection
Rather than using a conventional carburettor, the LX250R is equipped with a Bosch electronic fuel injection system.
The EFI system electronically manages fuelling, giving the LX250R a more sophisticated engine-management setup than the carburetted bikes elsewhere in the 10TEN JHL range.
Plastic radiator covers provide protection around the cooling system without adding unnecessary weight or bulk to the bodywork.
Full-Size Motocross Chassis
With a 1500mm wheelbase, 960mm seat height and overall dimensions of approximately 2170 × 830 × 1290mm, the LX250R is a full-size machine.
Its 21-inch front and 19-inch rear wheel combination follows the conventional motocross format. The larger front wheel is designed to roll effectively through ruts, braking bumps and rough ground, while the 19-inch rear helps retain responsive motocross handling.
This is not a junior pit bike or beginner’s model. Its dimensions, power and riding position are intended for suitably experienced riders who are physically capable of handling a full-size motocross bike.
Always consider rider height, inside-leg measurement, weight, experience and confidence before purchasing.
DID Rims and CNC Aluminium Hubs
The LX250R runs genuine DID aluminium rims with CNC-machined aluminium wheel hubs.
The wheels are fitted with Pneumax motocross tyres in the following sizes:
- Front tyre: Pneumax 90/100-21
- Rear tyre: Pneumax 100/90-19
Wheel locks are fitted at both ends, helping to prevent the tyres from moving around the rims when using lower pressures for off-road riding.
Adjustable KYB Suspension
One of the standout features of the LX250R is its adjustable KYB suspension.
The adjustability allows the suspension to be set up more appropriately for the rider’s weight, riding style, track and ground conditions.
At the rear, the shock works through a CNC-machined aluminium alloy linkage system. The linkage is paired with an aluminium alloy welded swingarm, reducing the use of heavier steel chassis components.
Combined with the 21/19 wheel setup, this gives the LX250R a specification clearly focused on motocross riding rather than simply being a larger recreational pit bike.
Hydraulic Disc Brakes
Hydraulic disc brakes at the front and rear provide the stopping power.
The braking system is paired with GG-grade brake pads, giving the bike a braking specification suited to its performance and intended off-road use.
Stainless steel footpegs provide a secure platform when riding standing up, while the rear brake pedal, gear lever and side stand are manufactured from aluminium alloy.
Higher-Spec Cockpit Components
The LX250R uses a Series 7 aluminium alloy reducing handlebar, giving the rider a purposeful full-size cockpit.
A CNC-machined aluminium steering stem finished in black completes the front-end control arrangement.
These weight-conscious aluminium components complement the bike’s motocross-focused chassis and suspension specification.
DID Final Drive
Power is transferred to the rear wheel through a heavy-duty 520 DID chain.
The final-drive setup uses a 13-tooth front sprocket and 50-tooth aluminium rear sprocket, providing gearing intended for off-road motocross use.
The DID chain and wheel equipment are among the recognised branded components used across the LX250R.
Motocross-Focused Equipment
A compact six-litre motocross-style fuel tank helps keep the bodywork slim around the rider.
There is no headlight or unnecessary road-style equipment. Instead, the specification remains focused on closed-course off-road riding.
An hourmeter is fitted as standard, making it easier to monitor engine running time and keep track of servicing intervals.
The bike is finished with a black frame, stainless steel and aluminium exhaust and distinctive 10TEN and JHLOFR graphics.

Who Is the LX250R For?
The LX250R is designed for experienced riders looking for a full-size, motocross-focused machine rather than a recreational pit bike or general-purpose trail model.
Its 42 hp engine, 960mm seat height, five-speed manual gearbox and adjustable KYB suspension make it unsuitable as a first off-road motorcycle.
The LX250R should appeal to riders who specifically want 21/19-inch motocross wheels, a lighter and more performance-led component package and recognised equipment from Bosch, KYB and DID.
For the correct rider, the 10TEN JHL LX250R offers a serious specification at a highly competitive price point.
