The Yokomo BB-105F-2 flanged bearings are manufactured to match YZ-870C bearing locations with a snug, secure fit. Their 5.0x10.0x4.0mm dimensions make them compact yet sturdy, minimising play in rotating assemblies.
Built for reliable rolling and long service intervals, these bearings help reduce friction and heat generation in drive components. The flange element keeps the bearing square to the shaft, aiding stability during aggressive driving.
These BB-105F-2 bearings are a straightforward swap for worn parts and a practical upgrade to sharpen handling on the YZ-870C. By cutting rolling resistance, they contribute to smoother throttle transitions and longer part life.
