Product Details

Hot Rods is well-known for making strong, reliable engine components for performance motorcycles. This bottom end kit is built for 125cc two-stroke dirt bikes, specifically covering models like the 125 SX (2018-2021), 125 XC (2021), MC 125 (2021-2023), and TC 125 (2018-2022). If you're rebuilding the lower half of your engine, this kit gives you the essential parts to get your bike running smoothly again.

Inside this kit, you'll find a new crankshaft, connecting rod, and the necessary crankcase bearings and seals. These are critical parts for the rotating assembly in your engine. The crankshaft is the heart of the power delivery, and a fresh, well-balanced one from Hot Rods ensures smooth operation and consistent power. The connecting rod transfers the force from the piston to the crankshaft, and having a strong rod is vital for handling the stresses of riding. The included bearings reduce friction and wear, while the seals keep oil where it needs to be and contaminants out.

When you're tackling a bottom end rebuild, having all these key components in one package saves you time and ensures you have compatible parts. This kit is designed to fit right into the specified models, making the rebuild process more straightforward. It’s a solid option for anyone looking to restore their 125cc dirt bike's engine performance or prepare it for demanding use.
