Hot Rods 15-20 KTM 450 SX-F Factory 450cc Main Bearing & Seal Kit

The main bearings in your KTM 450 SX-F are critical for smooth crankshaft rotation. This kit from Hot Rods includes the necessary main bearings and seals to get your engine rebuilt or refreshed. These are high-speed C3 rated bearings, meaning they have a wider internal clearance than standard bearings, which is important for handling the heat and expansion that comes with high-RPM operation.

Choosing a Hot Rods kit is a solid option when you need to replace worn-out bearings without going the full OEM route. They are built to meet or exceed original equipment specifications, so you can be confident in their performance and durability. This kit is designed to fit your 2015-2020 KTM 450 SX-F, making it a straightforward replacement for your engine's core rotating assembly.
