Specs At A Glance

Good To Know

Q: Does this kit fit both the KDX200 and KDX220? A: Yes, the kit is listed for both models across the 1989 to 2006 range, but confirm your exact year and engine code before ordering. Q: Is a shop press required to install it? A: Yes, fitting a connecting rod kit involves pressing the crankpin and truing the crank, so proper tools and experience are needed.

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