Protect a Hard-to-Replace Vintage KX250 Engine Case
A broken or derailed drive chain can bunch around the countershaft sprocket and strike the engine case with considerable force. On a vintage KX250, that can mean expensive damage to an increasingly difficult-to-replace engine case.
The MSV Racing Petite Billet Case Saver and Sprocket Guard provides a strong, purpose-built barrier around this vulnerable area without the bulk of an oversized sprocket cover.

Purpose-Built Vintage KX Protection
Replacement engine cases for early Kawasaki KX250 models are becoming harder and more expensive to locate. A case saver is a relatively small upgrade that can help prevent a chain problem from becoming a major engine repair.
The MSV Racing design surrounds the countershaft sprocket area with rigid billet-aluminum protection while maintaining a clean, compact appearance.
No case saver can guarantee protection during every chain failure, but it provides an important additional layer of defense around one of the engine’s most vulnerable areas.
One-Piece 6061-T6 Billet Construction
Each case saver is precision CNC-machined from a solid piece of 6061-T6 billet aluminum for strength, accurate fitment and long-term durability.
Its petite profile provides the needed protection and sprocket clearance without unnecessary material or bulk.
Fits Up to a 14-Tooth Front Sprocket
The case saver provides clearance for front sprockets up to 14 teeth, giving riders flexibility when selecting gearing for vintage racing, trail riding or restoration builds.
Always verify adequate clearance between the chain, sprocket and case saver before operating the motorcycle—especially after changing gearing.
Direct Bolt-On Installation
The case saver installs using the original mounting locations with no drilling, grinding or permanent engine modifications required.
