Motorcycle and Scooter Inner Tubes

Inner tubes for motorcycles and scooters are essential for the proper functioning of tires with non-tubeless rims. The right choice depends on the type of vehicle, tire size, and use. Here's a practical guide:

🛞 1. When inner tubes are needed

• Non-tubeless tires, i.e. on non-airtight rims (especially older models, enduro, cross, trial motorcycles, 50-125cc scooters).

• Some off-road models also prefer tubeless tires for durability and ease of repair.

📏 2. How to choose the right inner tube

✅ Compatible size

It must match the one indicated on the tyre (e.g. 120/90-18 → tube for 120/90-18 or compatible with 110-120/90-18).

✅ Valve

• TR4 : straight valve with thread, typical for motorcycles.

• TR87 : 90° bent valve, often for scooters or small wheels.

• TR6 / TR13 : Less common but present in some configurations.

✅ Thickness

• Standard : ~1.5 mm – normal road use.

• Heavy Duty : ~2-3 mm – increased puncture resistance, ideal for enduro or touring.

• Ultra Heavy Duty : up to 4 mm – extreme racing/off-road use (e.g. Michelin UHD, Metzeler Mousse if you want to go overboard).

🔧 3. Recommended brands

• Michelin – very widespread and reliable (standard and UHD).

• Pirelli – good for road and touring use.

• Metzeler – excellent for enduro/dual-sport.

• Kenda / Heidenau – economical and robust.

• Vee Rubber / Duro – cheaper but good for scooters or city bikes.

🧠 4. Helpful tips

• It's always best to change the inner tube when you change the tire.

• Avoid creases and pinches during assembly.

• Check compatibility with the rim and valve hole.

• Always carry a spare camera if you go off-road or on long trips.
