Protect a Hard-to-Replace Vintage KX250 Engine Case

A broken, loose or derailed chain can become trapped around the front sprocket and strike the engine case with considerable force. On a vintage Kawasaki KX250, replacement cases can be difficult and expensive to locate.

The MSV Racing billet case saver places a strong aluminum barrier around the countershaft sprocket area to help reduce the risk of serious engine-case damage.

It is a practical upgrade for:

• Vintage motocross racing
• KX250 restorations
• Trail and recreational riding
• Period-correct performance builds
• Riders replacing an original or damaged sprocket guard

Precision-Machined 6061-T6 Billet Aluminum

Each KX250 case saver is CNC-machined from durable 6061-T6 billet aluminum for an accurate fit, excellent strength and long-lasting performance.

Unlike thin stamped or molded guards, the billet construction provides a rigid layer of protection around one of the engine’s most vulnerable areas.

Petite, Low-Profile Design

The compact profile provides protection while maintaining a clean appearance and adequate clearance around the front sprocket.

This version is designed around the commonly used 14-tooth countershaft sprocket, making it an excellent choice for stock-style gearing and many vintage racing applications.
