Chimera Crank Case Gasket Grom Monkey Super Cub 125

The Chimera Crank Case Gasket is an aftermarket replacement part designed for the right-side crankcase cover — the clutch side — on Honda's popular 125cc small-displacement platform. It provides a direct fit for the 2014–2020 Grom 125 (JC61 and JC75 chassis codes), 2018–2021 Monkey 125 (JB02), and 2019–2021 Super Cub 125 (C125, JA48), all of which share the same 4-speed engine architecture. Whether you're performing a clutch inspection, oil pump service, or any other maintenance that requires removing the right-side cover, a fresh gasket is essential for preventing oil leaks.

Reusing a crankcase gasket after removal is generally not recommended, as the material deforms under clamping pressure and may not reseal properly. Having a replacement gasket ready before starting work avoids the frustration of waiting for parts mid-job. This Chimera gasket serves as a cost-effective alternative to the OEM Honda part, making it practical to keep one or two spares in your toolkit for routine maintenance on these widely owned small-bore Honda motorcycles.
