BikeMaster 5.00/5.10-16 TR15Oc Tube - 374624

The BikeMaster 5.00/5.10-16 TR15OC Motorcycle Inner Tube (Part #374624) is a natural rubber inner tube designed to fit 16-inch motorcycle wheels accepting 5.00 or 5.10 section-width tires. Whether you're replacing a worn tube on a classic cruiser, a vintage street bike, or a retro-styled motorcycle that runs tube-type tires, this BikeMaster tube delivers reliable, road-ready performance at an accessible price point.

Key Features & Benefits

• Seamless Construction: BikeMaster manufactures this tube with a seamless process, which eliminates weak seam points that can be prone to failure — a meaningful advantage for long-term durability and consistent air retention.
• Natural Rubber Material: Made from natural rubber, this tube offers the flexibility and stretch needed to seat evenly inside the tire casing, reducing the risk of pinching or uneven pressure spots during installation.
• Heavy-Duty Valve Stem (TR15OC): The TR15OC is an offset rubber valve stem — the angled design makes it easier to access and inflate in wheels where a straight stem would be awkward to reach, a practical benefit on many classic motorcycle rim configurations.
• Individually Packaged with Part Number & Size: Each tube ships in its own labeled box clearly marked with the part number and size, making it easy to confirm you have the right tube before you tear down your wheel.
• Fits Dual Size Range (5.00 & 5.10): The tube is rated for both 5.00 and 5.10 section-width tires on 16-inch rims, giving it broad compatibility across a range of tire sizes that share the same rim diameter.

Fitment

This tube is designed for 16-inch motorcycle wheels running 5.00 or 5.10 section-width tube-type tires. This size is commonly found on classic American cruisers, vintage street motorcycles, and certain retro-styled bikes — particularly those running wide rear tires on 16-inch rims. Always confirm your wheel rim diameter and tire sidewall size before ordering. If your tire sidewall reads 5.00-16 or 5.10-16, this is the correct tube size. Tires with different rim diameters (15", 17", 18", etc.) or significantly different section widths will require a different tube. Use the fitment checker on this page or contact our team to confirm compatibility before purchasing.

Frequently Asked Questions

Q: What does "TR15OC" mean on this tube?
A: TR15OC designates the valve stem type. It is an offset rubber center valve stem — the "offset" or angled design positions the stem at an angle rather than perfectly perpendicular, which makes inflation easier on wheels where tire clearance or rim design limits straight access to the valve.

Q: Will this tube fit both a 5.00-16 and a 5.10-16 tire?
A: Yes. BikeMaster rates this single tube (374624) for use with both 5.00-16 and 5.10-16 section-width tires on 16-inch rims. The natural rubber construction allows the tube to expand appropriately to fill either tire size.

Q: Is this tube suitable for tube-type motorcycle tires only?
A: Inner tubes are only used with tube-type (non-tubeless) tires and compatible rims. Do not use this tube inside a tubeless tire mounted on a tubeless-rated rim unless specifically instructed otherwise by your tire or wheel manufacturer.

Q: How is this tube packaged — can I confirm the size before opening?
A: Yes. BikeMaster individually packages each tube in a labeled box that clearly displays the part number (374624) and the tire size (5.00/5.10-16) on the outside, so you can verify you have the correct tube before breaking the seal.
