Specs At A Glance

Good To Know

Q: How many pistons come in this set? A: Three pistons are included, matching the 600cc triple in the Indy XLT 600 Classic. Ordering one set covers all three cylinders for a full top-end rebuild.

Q: Do I need to bore the cylinders to use these? A: These are standard bore pistons, so they suit cylinders that are still within standard bore tolerance. If the cylinder walls are scored or worn past spec, machining or a larger piston size would be needed instead.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
