• Suitable for road use - no change to the operating permit required
• Direct replacement for the stock cylinder without adjustments to the engine housing or connections
• Piston rings beveled on one side - fit only in one direction into the piston ring groove; conical side must point upwards, otherwise the piston cannot be inserted into the cylinder liner
