Specs At A Glance

Good To Know

Q: What does .040 overbore mean for my cylinder? A: The .040 oversize piston requires the cylinder to be bored and honed to match the larger 85.00 mm diameter, so machine work is needed before installation.

Q: Will this kit include everything I need for a top end? A: The kit supplies the piston, rings, wrist pin, and circlips, but you should verify your machine's specific requirements and any gaskets needed for reassembly.

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