How to Choose the Right Size
Trials engines use pistons in small incremental size codes (A, B, C, D).

• Match the piston size code to your cylinder stamp (e.g. “A” → “A” piston).
• For worn cylinders, step up one code size (A → B → C).

• When all codes are used, the cylinder must be re-plated or replaced.

⚠️ Always check the code stamped on your cylinder before ordering to ensure proper fit and avoid engine damage.
