This JAZRIDER bearing kit is intended for model builders and club racers who want a durable, low-maintenance rolling solution for Kyosho Mini-Z MR01, MR02, MR03 and F-1 chassis. The shielded metal design protects internal components while delivering steady rotation across typical hobby track conditions.
Shielded bearings block particulate ingress and help retain lubricants, which reduces routine maintenance and extends usable life compared with open bearings. They are a pragmatic choice for daily drivers and those who prefer fewer service intervals.
The set supports MR01, MR02, MR03 and F-1 Mini-Z chassis. When fitting, confirm bearing seats and adjacent components are clean and free of burrs to ensure correct seating and alignment for reliable performance.
