Hot Rods 90-10 KTM 300 MXC 300cc Wrist Pin Bearing

This is the Hot Rods wrist pin bearing for your KTM 300 MXC, covering models from 1990 through 2010. It's a critical component in the top end of your engine, connecting the piston to the connecting rod. A well-functioning wrist pin bearing ensures smooth operation and longevity of your engine's moving parts.

This bearing is constructed from hot-rolled ASTM 4115 steel, a strong material chosen for its durability in high-stress applications. It's then case-hardened to a hardness level of 58-62 Rc, which means the outer surface is made very hard to resist wear and deformation, while the inner core remains tougher. This process helps it stand up to the constant friction and impact it experiences during combustion cycles.
