As a professional motorcycle brake disc supplier, Max Trading's KTM Off-Road Vehicle Rear Brake Disc is not designed for on-road performance, but rather around the core concept of "high temperature resistance, deformation resistance, and strong environmental adaptability." It is specifically designed to handle the extreme conditions common in off-road riding, such as mud, severe bumps, and high-temperature impacts. This design philosophy clearly distinguishes it from brake discs for street bikes like the GSXR 600, which prioritize linear braking performance on smooth roads.
The performance advantages of this rear brake disc are mainly reflected in three key technical dimensions:
Structural Innovation
Structurally, the product is optimized to handle frequent impact loads and irregular forces in off-road environments, effectively improving overall rigidity and deformation resistance. Even during continuous heavy braking and on complex terrain, it maintains stable brake disc flatness, preventing vibration and uneven wear caused by thermal stress or external impacts.
Material Upgrade
In terms of material selection, this series of rear brake discs uses a special steel alloy formula more suitable for high-temperature and high-load conditions, balancing heat resistance and toughness. Under prolonged off-road riding or high-frequency braking conditions, it effectively suppresses thermal degradation and thermal fatigue, ensuring consistently stable braking force output.
Functional Adaptation
In terms of functional adaptation, the KTM Off-Road Vehicle Rear Brake Disc takes into account complex environments such as mud and water, improving drainage and actual braking reliability. Even in muddy, wet, or high-temperature environments, it maintains clear and controllable braking feedback, meeting the dual demands of safety and handling for off-road riders.
Core advantage: Compared to traditional circular flat discs, the wavy edge design can reduce brake pad contact area redundancy by more than 40%, ensuring braking force while reducing the probability of mud accumulation, especially suitable for environments with multiple impurities such as rainforests and mud.
Derivative value: The wave contour can guide the airflow to quickly pass through the disc surface, combined with surface grooves to form a "self ventilation" effect. The heat dissipation efficiency is 30% higher than that of ordinary discs, effectively suppressing the heat dissipation phenomenon after continuous braking.
This rear brake disc is engineered specifically for KTM Off-Road Vehicle Rear Brake Disc, integrating hole optimization technology and dimensional standardization design to strike a perfect balance between braking performance, lightweight feature and handling flexibility, which is an ideal upgrade part for both daily off-road riding and racing scenarios.
The core advantage of this brake disc lies in its meticulously designed hole structure, which serves dual purposes of weight reduction and heat dissipation:
Variable-diameter heat dissipation holes: The disc is equipped with evenly distributed variable-diameter heat dissipation holes. This design not only cuts down the overall weight of the disc by 15%-20% but also significantly boosts air circulation around the disc surface. Enhanced air flow can quickly take away the heat generated during braking, effectively preventing brake fade caused by high temperature and ensuring stable braking force in long-time off-road driving.
Racing-grade T-Drive bolt-free connection: For high-performance racing models, this brake disc adopts a specialized "T-Drive" bolt-free connection structure. Different from traditional bolt fixation, it transmits torque through T-pins. This innovative structure further reduces the weight by 25% compared with conventional bolt-fixed discs, while also eliminating the risk of bolt loosening under intense off-road vibration, ensuring more reliable power transmission and braking response.
To adapt to the diverse needs of KTM Off-Road Vehicle Rear Brake Disc, this rear brake disc follows strict dimensional standardization principles:
Unified 260mm diameter: Mainstream models of the brake disc uniformly adopt a 260mm diameter specification. A typical example is the model 77709160000, which is fully compatible with KTM MX/Enduro series vehicles produced from 2003 to 2025.
Balanced performance: The 260mm diameter is carefully calibrated to balance braking torque and handling flexibility. It provides sufficient braking force to meet the high-demand braking requirements of off-road riding, while avoiding the "dragging sensation" that large-sized discs tend to cause on bumpy roads. Riders can enjoy more agile handling and precise braking control in complex off-road terrain.

1. Adopting a duplicate process of "sandblasting+phosphating" to form a rough and wear-resistant surface texture, which can boost the adhesion of brake pads and reduce the scratching of the disc surface by mud and sand.
The disc brake disc of Max Trading is forged with high-performance stainless steel, with a hardness of HRC 38-4
2. Its wear resistance is 50% more than that of ordinary stainless steel, and it can bear high temperatures over 600 ℃ without deformation.
3.The wavy edges are treated with R3-R5 rounded corners to avoid impact damage from tree branches and rocks on the disc surface during off-road driving, and to extend the service life of the brake pads.
