MUC-OFF offers a universal muffler cap, designed to effectively protect your engine when cleaning or servicing your motorcycle. Thanks to its watertight seal, it prevents water, dust or any other contaminant from entering the exhaust system, thus preserving your machine's performance. This cap is compatible with both 2-stroke and 4-stroke engines, thanks to a removable sleeve specially designed for 4-strokes, offering an adaptable and reliable solution, whatever your engine configuration.
