Friction is a huge problem in the engineering world. It takes the useful energy produced by the motor and converts it into harmful heat that, once accumulated, can destroy the whole assembly. Moreover, while accumulating thermal energy, the components subjected to friction suffer from abrasive wear of their surfaces. Friction in the engine can result in quick wear and/or overheating of the moving parts, yet it affects performance. Now, you know why every single shaft in the vehicle is supported by a bearing, or a few of them – these parts reduce friction.
While doing their crucial job though, the bearings themselves encounter wear. In most cases, bearings (especially engine bearings – the ones supporting the crankshaft), cannot be repaired, only replaced. The good news though is that these components are not that expensive. In fact, unless you’re doing the repair job yourself, it will cost you more to disassemble the engine to get to these worn-out shaft holders. And that’s the reason why only top-notch engine bearings make sense for your motocross bike. You can find and order them in our online store.
