Kyosho Rear Ball Bearing 14X25X6mm Ke21Sp-Ke25Sp

The Kyosho Rear Ball Bearing 14x25x6mm is a genuine replacement part designed to match the specified rear bearing dimensions for select Kyosho nitro engines. With a 14 mm inner diameter, 25 mm outer diameter and 6 mm width, it provides the correct sizing for rear crankshaft support. Suggested compatibility includes Kyosho KE21SP and KE25SP engines; please verify your engine manual and bearing size before ordering.

Replacing a worn rear bearing can help maintain smooth rotation and reliable sealing inside the crankcase. If you notice excessive play, unusual noise or fuel residue near the backplate area, refreshing the rear bearing is common maintenance to restore consistent engine performance.
