This 325-18 inner tube is built for riders who need steady tyre pressure and a tube that can handle everyday roads. Made from butyl rubber—now a go-to in the motorcycle world—it holds air way better than natural rubber. If you ride often, that means less hassle of constantly checking tyre pressure.
It has a section width around 90mm and weighs about 460g, so it sits balanced inside the tyre without adding extra vibration or drag. The TR4 valve is super common on motorcycles, making it easy to top up air or adjust pressure at any roadside shop or gas station.
Motorcycles take way more of a beating from the road than cars do—small stones, cracks, sudden bumps, or rough country roads can stress a tyre fast. Butyl rubber’s flexibility lets the tube mold smoothly inside the tyre, while resisting those sudden pinches that happen when you brake hard or hit a pothole. This stability also cuts down on heat buildup, especially when you’re riding at higher speeds for longer stretches.
Riders will also love how it performs in different weather. It doesn’t get too stiff on cold mornings, and when the road’s scorching under the sun, it still holds pressure like a champ. For daily commuters, that means fewer unexpected issues and more consistent handling.
Before packaging, every tube gets checked for leaks and surface evenness—so once you install it, you know it’ll work as it should. That also helps tyre shops avoid installation headaches
and keeps riders happy.
Whether you’re using your motorcycle for daily work runs, short commutes, or weekend rides, this inner tube is a practical pick. It helps with safe cornering and braking, and extends your tyre’s lifespan too. If you just want a reliable tube that doesn’t require extra maintenance worries, this 325-18 butyl inner tube is right up your alley.
