ProX Piston Kit Beta Bore

The ProX piston kit line for Beta off-road motorcycles is a complete engine piston replacement (rebuild) kit. It is made for riders who want to restore engine performance and reliability in 2-stroke and 4-stroke dirt bikes. Each kit is built as an OEM-style replacement and is available in standard and oversize bore options.

Key Features:

• Quality piston alloy: Uses a low-expansion, low-friction aluminum alloy, the same type of alloy used by major Japanese engine manufacturers.
• Complete kit: Supplied with piston rings, wrist pin and circlips, so the kit is ready to install.
• OEM-style break-in coating: Uses an OEM-style coating on the piston to help with initial engine break-in.
