Upgrade your build with the Suzuki RM125 RM250 aluminum subframe 2003-2008 (SKU 02-4803) from AC Racing—a lightweight, bolt-on replacement designed to restore OEM-style fitment while delivering the strength and rigidity serious riders demand. Whether you’re replacing a bent stock subframe after a crash or refreshing a full rebuild, this subframe provides a solid foundation for proper seat and rear plastics alignment and long-term durability.

Made in the USA using U.S. materials and expert craftsmanship, this RM125/RM250 aluminum subframe is heli arc welded for maximum strength and a true handcrafted look. It’s built from thick wall 3/4" aluminum tubing (.125 wall) to increase rigidity and resist fatigue from vibration, hard landings, and aggressive riding conditions.

For a secure, reliable bolt-on fit, all mounting points are CNC machined from billet aluminum, helping ensure consistent alignment where it matters most. Each subframe is also tumble finished with ceramic spheres for a clean, uniform finish that looks as good as it performs.
