On a motocross or enduro bike, which is washed after every ride, the problem arises every time. This bung solves it in ten seconds and, thanks to its two-part construction, works on both two-stroke and four-stroke engines: it's the classic five-euro accessory that saves hundreds of euros in damage. The only thing never to forget is to remove it before starting the engine.\u003c\/p\u003e\n\n\n\u003cdiv style=\"background:#f0f7f0;border-left:4px solid #28a745;padding:14px;margin:20px 0;border-radius:4px;\"\u003e\n\n\u003cstrong\u003e🛡️ Warranty and quality – Moon Bike S.r.l.\u003c\/strong\u003e\u003cbr\u003e\nOriginal Muc-Off product.
