Protect Your KX250 Engine Case

A broken, loose or derailed drive chain can bunch around the countershaft sprocket and strike the engine case with tremendous force.

On an older Kawasaki KX250, this type of damage can lead to:

• Cracked or broken engine cases
• Oil leakage
• Damage around the countershaft area
• Expensive engine removal and repair
• Difficulty locating replacement vintage cases
• A ruined race or riding trip

The MSV Racing Billet Case Saver places a strong aluminum barrier around this vulnerable area to help reduce the risk of serious engine damage.

Fully Radiused Chain-Deflection Profile

The interior surface of the MSV Racing case saver is smoothly radiused rather than sharply squared.

If the chain breaks or leaves the front sprocket, the curved profile is designed to help redirect the chain’s forward energy downward and away from the engine case. This reduces the opportunity for the chain to bunch against a sharp internal edge and concentrate force directly into the case.

No case saver can guarantee protection during every chain failure, but this purpose-built profile provides an important additional layer of defense.

One-Piece 6061-T6 Billet Construction

Each case saver is precision-machined from a solid piece of 6061-T6 billet aluminum.

Benefits include:

• Excellent strength
• Lightweight protection
• Accurate fitment
• Consistent sprocket clearance
• Resistance to bending and deformation
• Clean, factory-quality appearance
• Long-lasting durability

Unlike welded or multi-piece designs, the one-piece billet construction eliminates welded joints and provides consistent strength throughout the guard.

Compatible with Multiple Sprocket Sizes

The design provides clearance for multiple commonly used front-sprocket sizes, making it suitable for riders who adjust gearing for different conditions.

This can benefit riders who tune their KX250 for:

• Motocross
• Sand and dune riding
• Tight trails
• Hill climbing
• Vintage racing
• General recreational riding

Always confirm clearance between the chain, sprocket and case saver before operating the motorcycle, especially after changing sprocket size or gearing.

Uses OEM Mounting Fasteners

The MSV Racing case saver installs using the motorcycle’s original mounting fasteners.

Installation Benefits

• Direct bolt-on design
• No drilling
• No grinding
• No permanent engine modifications
• Uses the original mounting locations
• Installation can typically be completed in only a few minutes

Inspect the original bolts before reuse and replace any damaged, corroded or incorrect hardware.

Important Chain-Maintenance Notice

A case saver adds protection, but it does not replace proper drivetrain maintenance.

Before every ride:

• Inspect the chain for damaged or stiff links
• Verify correct chain tension
• Check chain alignment
• Inspect the front and rear sprockets
• Confirm mounting bolts are secure
• Verify adequate chain and sprocket clearance

Replacing worn chains and sprockets before failure remains the best way to protect the motorcycle.
