The HOT Rods Bottom End Kit is a complete OE‑replacement solution for KTM 2‑cycle, off‑road engines up to 50 cc. Engineered from 4140 steel, the kit supplies a precision‑machined crankshaft, a full gasket set, and the main bearings and seals required for a full crankshaft rebuild. All components are matched to the original equipment specifications, ensuring proper clearances and reliable performance for demanding off‑road applications.
Designed as a turnkey package, the kit contains everything needed to finish a bottom‑end installation except the water‑pump seal, which must be sourced separately. The steel construction and standard stroke length maintain the engine’s original geometry while delivering the durability expected from a high‑performance rebuild. This comprehensive kit streamlines the rebuild process, reducing part count and installation time for riders and technicians alike.
