Pistons

Power, precision and reliability start from within. At RPM Moto we understand that your pistons are more than moving parts, they’re central to the engine’s function, performance and longevity. Whether you’re rebuilding, upgrading or maintaining your ride, our piston kits and replacement options are built for riders who demand quality.

Why Choose RPM Moto Pistons & Kits

• Core engine component: The piston moves inside the cylinder to convert combustion into motion, making it one of the most critical parts of your engine. 

• Quality fit & material: Our pistons are selected for fitment, correct size, and are built with materials capable of handling real-world conditions, including high revs, heat and wear.

• Support for rebuilds and upgrades: Whether you’re doing routine maintenance, performance tuning or full engine overhaul, the right piston kit ensures you’re starting from a strong base.

• Compatibility across makes and models: We carry piston kits matched to a wide range of motorcycle brands and engines so you can find the right fit for your machine.

• Australia-wide dispatch & rider support: Order online with RPM Moto and receive parts across Australia. Our team can help you check the correct bore size, ring fitment and build-ready specifications.

• Select international shipping available: RPM Moto proudly offers limited worldwide delivery on select parts and kits so riders beyond Australia can access genuine, high-quality motorcycle components with confidence.

What You’ll Find in Our Piston & Kit Range

• Standard replacement piston kits: High-quality components for bikes whose pistons and rings have worn, for routine maintenance or moderate rebuilds.

• Performance / forged piston options: Upgraded kits made from premium materials for riders looking to increase engine performance, resilience or rev limits.

When It’s Time to Replace or Upgrade Your Pistons

• You notice engine symptoms like loss of power, excessive oil consumption, or low compression - classic signs of piston/ring wear.

• You’re performing a top-end rebuild or long-life service and want fresh components for lasting reliability.

• You’ve upgraded your bike (higher performance tune, higher revs) and need internal parts to match the new demands.

• Your engine sees heavy use (track days, off-road, high hours), so some components like pistons become wear items under those conditions.

• You’ve spotted visible wear in the cylinder or piston skirt, or feel roughness or knocking near the top of the bore.
