Rebuild the Heart of Your Engine: Premium Bottom-End Kits

When your crank starts knocking or your bottom-end seals begin leaking oil, it’s time to refresh the engine’s foundation with an RPM Moto Bottom-End Kit. Designed for motorcycles, ATVs, and UTVs, our kits restore strength, precision, and longevity to your ride.

What Is a Bottom-End Kit?

A bottom-end rebuild focuses on the engine’s lower half—crankcases, crankshaft, bearings, seals, gaskets, and connecting rods—distinct from top-end services involving pistons and valves. RPM Moto bundles all essential parts together (“one-box rebuilds”), saving you time and ensuring compatibility.

What’s Included?

Each RPM Moto kit typically features:

  • Crankshaft assembly (precision-balanced OEM or aftermarket crank)
  • Main bearings, often top-grade or OE-spec
  • Seals & gasket set for bottom-end sealing integrity
  • Supporting bearings & hardware, depending on model

Higher-end packages might include rod kits and even top-end items for full rebuild capability.

Why Use a Bottom-End Kit?

  • Precision Rebuild: Factory assembly and strict tolerances minimize misalignment and crank run-out .
  • Improved Durability: Forged or double-forged cranks with shot-peening resist fatigue and wear .
  • All-in-One Convenience: Complete solution under one part number—no need to source multiple components.
  • Performance-Ready: Ideal for strengthening stock engines or preparing for high-stress builds.

Choose the Right RPM Moto Kit

  1. Match Your Model – Kits are bike-specific—CRF, KTM, Yamaha, Suzuki and more.
  2. Select Strength Level – OEM-style for daily use; heavy-duty or stroker for racing/upgrades.
  3. Verify Contents – Most kits have crank, bearings, gaskets; some include rod kits or top-end extras.

Why RPM Moto Stands Out

  • Sourced from Trusted Brands – Wiseco, Hot Rods, Pro-X—precision-engineered in one box.
  • Complete Transparency – Every kit lists included components, specs, and fitment details.
  • Gold Coast Dispatch + Aussie Support – Fast delivery across Australia since 2007.
  • Technical Expertise – Hear from experienced rebuilders:
