Product Details

If you're looking to rebuild the bottom end of your 2007-2015 KTM 125 SX, this bottom end kit from Hot Rods is a comprehensive solution. It bundles all the essential components you need into one convenient package, saving you the hassle of sourcing each part individually. This kit is designed to get your engine back to running smoothly and efficiently.

Inside this kit, you'll find a new crankshaft, which is the heart of your engine's rotating assembly. It also includes a main bearing and seal kit, crucial for ensuring proper support and sealing for the crankshaft. To complete the rebuild, a full top and bottom end gasket kit with seals is included, making sure you have everything needed for a leak-free assembly. This approach can save you both time and money compared to purchasing each of these items separately from the OEM.

For some models, there's even an option for a stroker crankshaft, which can alter the engine's stroke for potentially improved performance characteristics. When undertaking a bottom end rebuild, having all these critical components in one box streamlines the process and helps ensure a successful engine overhaul.
