Ceramic wheel bearing Yamaha Yz 125

High-performance ceramic wheel bearings for YAMAHA Yz 125

Raceet® ceramic motocross wheel bearings for Yamaha Yz 125 are designed to deliver improved off-road efficiency, maximum friction reduction and smooth rotation even in extreme conditions. Thanks to their high-density technical ceramic balls (hybrid technology: high-strength treated steel rings, Si3N4 ceramic balls), lighter and harder than standard steel bearings, they reduce energy losses at the wheels and optimize power transmission on loose terrain. The result: stronger acceleration, improved traction and greater stability during corner exits and technical sections. Suitable for motocross, supercross and enduro, these high-performance bearings are an ideal upgrade to improve responsiveness and reliability in intensive use, mud, sand or dusty environments.

Question

Boost your cross performance by reducing mechanical losses

Part of the engine power is absorbed by the internal resistance of rotating components, especially the original wheel bearings which are often heavily stressed in off-road riding. By installing Raceet® high-performance ceramic wheel bearings for motocross, you significantly reduce the friction coefficient, improve mechanical efficiency and fully exploit the potential of your Yamaha Yz 125. Designed to withstand high rotational speeds, heavy radial loads and the extreme stresses of motocross (mud, sand, jumps and repeated impacts), they provide enhanced durability, excellent thermal stability and increased resistance to wear and corrosion. Ideal for motocross, supercross and enduro seeking performance, traction and reliability in demanding racing or natural terrain conditions.

Ceramic wheel bearing technical specifications for Yamaha Yz 125

At the core of this technology are silicon nitride (Si3N4) ceramic balls, an advanced engineering material known for its low density, exceptional hardness and ability to maintain its mechanical properties at high temperatures. Their reduced mass lowers rotational inertia, allowing faster acceleration and more immediate response of the drivetrain and wheels. Their extremely dense structure also limits micro-deformation under load, ensuring consistent performance even at high rotational speeds.

The high-strength treated steel races ensure perfect compatibility with original hubs while benefiting from precision machining with micrometric tolerances. This high-precision finish allows optimal distribution of mechanical loads and a perfectly controlled contact surface, improving rotational stability and efficiency.

Overall performance is further enhanced by the use of reinforced polymer cages or high-performance PEEK cages. These advanced materials precisely guide the rolling elements, reduce parasitic vibrations and improve thermal dissipation. The internal guidance of the bearing remains stable even under high loads, promoting longer service life and quiet operation, even in demanding conditions such as racing, off-road riding or intensive training.
