Specs At A Glance

Good To Know

Q: Does this kit fit both the Ultra 260X and 260LX? A: Yes, this kit is listed for both the JT1500 Ultra 260X and 260LX from 2009 to 2010. Always confirm your exact model and year before ordering.

Q: Do I need to machine my cylinder for this piston? A: This is a standard bore piston kit, so it is intended for a cylinder that is still within factory bore specs. If your cylinder is scored or worn oversize, an overbore piston may be required.

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