Good To Know

Q: Does this kit include the piston itself? A: No, this is a bearing and gasket kit only; the piston must be ordered separately. It is designed to match a Size B standard bore 66.40mm piston for the Suzuki RM250.

Q: Will this fit other years of RM250? A: This kit is specifically for 2003-2005 RM250 models; earlier or later years use different bore sizes and gasket configurations, so verify compatibility by year and serial number.

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