Chain Kit for Luxxon 125 Enduro & Supermoto with Original Gear Ratio
A precisely matched chain kit for Luxxon 125 Enduro and Supermoto motorcycles ensures reliable power transmission from the engine to the rear wheel. Especially on 125cc motorcycles that are used daily in city traffic, on longer rides, or on off-road terrain, drivetrain components are exposed to significant mechanical loads. This chain kit combines a reinforced front sprocket, a precisely manufactured rear sprocket, and a double-reinforced motorcycle chain to support consistent power transfer and extended service life.
Original Gear Ratio for Balanced Performance
The sprocket combination corresponds to the original gearing used on many Luxxon 125 models. Maintaining the original gear ratio helps preserve the motorcycle’s factory riding characteristics while upgrading to durable drivetrain components.
- Front sprocket with 15 teeth
- Rear sprocket with 51 teeth
- Chain pitch 428
- Reinforced sprocket and rear sprocket design
- Double reinforced motorcycle chain for higher durability
This configuration supports consistent acceleration behavior and stable torque transmission during daily riding conditions, longer journeys, or demanding terrain.
Important Note Regarding Rear Sprocket Mounting
Luxxon 125 motorcycles were produced with different rear sprocket mounting designs. This chain kit is designed for vehicles equipped with a 4-hole rear sprocket mounting. It is essential to verify the mounting configuration on the motorcycle before purchasing.
- Rear sprocket with 4 mounting holes
- Some models use an alternative 5-hole mounting design
- The number of mounting holes must be checked directly on the vehicle

High-Precision Manufacturing Inspired by Racing Technology
The rear sprocket and front sprocket are manufactured from high-strength steel and designed for demanding mechanical loads. Advanced production processes ensure high dimensional accuracy and precise tooth geometry.
- Manufactured from high-grade steels Qste 420 / Qste 460
-
Diamond-Cut tooth profile for improved running characteristics
- Radial and axial runout tolerance below 0.1 mm
- CNC-machined center holes for accurate fitment
- Countersunk and deburred mounting holes
The precisely manufactured tooth structure allows smooth chain engagement and balanced load distribution between the chain and sprocket teeth. This reduces wear on drivetrain components and contributes to consistent power delivery.
Innovative Tooth Manufacturing Process
In cooperation with the University of Paderborn, the manufacturer developed an advanced production process for sprocket tooth structures. Compared with conventional milling methods, this technology enables more precise shaping of the gear profile.
The improved geometry allows the motorcycle chain to engage more evenly across the sprocket teeth, distributing loads more efficiently. As a result, drivetrain components may maintain their functional performance over longer operating intervals.
Double Reinforced Motorcycle Chain for High Load Capacity
The included chain features a double reinforced design developed for demanding riding conditions. During frequent acceleration, off-road riding, or longer tours, drivetrain chains are exposed to continuous tensile forces. A reinforced chain construction supports stable power transmission across all riding conditions.
- Double reinforced chain construction
- Designed for higher mechanical load capacity
- Suitable for extended riding distances
- Clip-type master link included for chain connection

Typical Use Cases for This Chain Kit
A worn chain kit can lead to irregular power transmission, increased drivetrain wear, and unwanted noise from the drive system. Replacing the chain, front sprocket, and rear sprocket as a complete set restores the balance of the drivetrain components.
This chain kit is suitable for riders who use their Luxxon 125 Enduro or Supermoto motorcycles for everyday commuting, touring rides, or off-road riding conditions and require a durable drivetrain setup with the original gear ratio.
