Cylinder Re-Boring • We offer a Reboring service (Not in house). • 10-14 day turn around. • Collection and delivery service available. Cylinder Re-Boring 71-100
Cylinder Re-Nikasil Plated Bores • Nickasil is the process as done by the manufacturers on all barrels. • Very hard finish and long lasting. • Beware of cheap alternatives i.e. Chroming, as not suitable for high performance engines. • Even if your bore is damaged, repair welding can be done before nicklesealing, and
barrel will look like new. • 10-21 day turn around. • Collection and delivery service available. • Any nickle bore barrel can be done. Cylinder Nikasil Re-Plating Cylinder Repair & Re-Plating

Piston Kits
ProX
ProX Piston Kits ProX pistons are precision machined on the latest, state of the art CNC equipment. The same low-expansion, low-friction piston alloy is used as is used for all major Japanese engine manufacturers. ProX piston kits are a first class solution to replace the original piston in your motorcycle. ProX piston kits for sleeved cylinders are available in standard size and a wide range of over sizes. ProX pistons for plated cylinders come in standard size, A, B, C, D & over sizes. All ProX piston kits are supplied complete with piston rings, wrist pin and circlips, ready to install!
ProX 2-Stroke Piston Kits
• ProX pistons are manufactured by the same factories in Japan that supply the OEMs. This ensures OEM quality but allows ProX to make improvements upon OEM designs when needed. • The majority of ProX 2-stroke pistons are cast from aluminum containing approximately 18% silicon. This material and manufacturing combination reduces thermal expansion, allowing pistons to be run at tighter tolerances and reducing wear. • ProX adds additional performance features to piston designs where they feel necessary. For example, some 2-stroke pistons will have wrist pin oiling holes drilled in the bottom of the pin towers. • A quality piston’s performance is only as good as the components it uses. ProX 2-stroke pistons come with OEM quality, Japanese rings to ensure durabilty and performance is consistent throughout the entire piston package.

ProX 2-Stroke Piston Kits
• ProX pistons are manufactured by the same factories in Japan that supply the OEMs. This ensures OEM quality but allows ProX to make improvements upon OEM designs when needed. • The majority of ProX 2-stroke pistons are cast from aluminum containing approximately 18% silicon. This material and manufacturing combination reduces thermal expansion, allowing pistons to be run at tighter tolerances and reducing wear. • ProX adds additional performance features to piston designs where they feel necessary. For example, some 2-stroke pistons will have wrist pin oiling holes drilled in the bottom of the pin towers. • A quality piston’s performance is only as good as the components it uses. ProX 2-stroke pistons come with OEM quality, Japanese rings to ensure durabilty and performance is consistent throughout the entire piston package.
ProX 4-Stroke Piston Kits
• ProX 4-stroke pistons for performance applications are forged, while others are cast. Because most motorcycle and ATV applications are high performance, the majority of ProX 4-stroke pistons are forged. • When treated properly, 4032 alloy offers greater strength and more wear resistance thanks to reduced thermal expansion and increased hardness. • ProX 4-stroke pistons’ alloy reduces the chances of microwelding in the ring grooves thanks to the additional hardness. • ProX pistons are designed and manufactured to OEM specifications at a minimum. Some designs are improved upon based on market need or an OEM weak point. • ProX only uses rings that come from reputable Japanese OE suppliers. A piston is only as good as its ring pack. • ProX 4-stroke piston kits include the piston, rings, wrist pin, and wire locks. They are available for a wide range of applications
