AR-PRO Motorcycle Inner Tubes, 2-Pack 2.50/2.75-17, Butyl Rubber

AR-PRO motorcycle inner tubes are a two-pack of butyl rubber replacement tubes for compatible dirt bikes, scooters, mopeds, and motorcycles with 17-inch (43.18 cm) rims.

• Two replacement inner tubes — keep a matching pair on hand.
• 2.50/2.75-17 (70/100-17) sizing — fits tires between 2.50 and 2.75 inches wide (6.35–6.99 cm).
• Butyl rubber construction — designed for impact absorption and puncture resistance.
• Compatibility across many 110cc, 125cc, and 140cc bikes — covers a range of dirt bike, pit bike, and motocross applications.
• In-house tested aftermarket parts — tested by AR-PRO for consistent quality.

A replacement inner tube needs to match the tire size, not just the motorcycle model. This two-tube set is made for riders replacing tubes on compatible 17-inch-wheel motorcycles, including dirt bikes, scooters, and mopeds. Before choosing a size, compare the marking on your existing tire’s sidewall with the tube size.

Which tire sizes do these AR-PRO inner tubes fit?

They fit tires marked 2.50/2.75-17 or 70/100-17, with tire widths from 2.50 to 2.75 inches (6.35–6.99 cm). The tubes are intended for most scooters and dirt bikes with 17-inch rims. The size may also be stamped on a tire as 70/100-17, so compare the full sidewall marking rather than relying on wheel diameter alone.

• Also usable as a substitute for 2.25/2.50-17 tubes.
• Good to know: confirm the existing tire’s sidewall size before selecting a replacement.

What motorcycles and riding applications are they compatible with?

AR-PRO inner tubes fit many motorcycles using the matching tire size, including models from Honda, Coolster, and Kawasaki. Examples include Honda Cub and Super Cub series, Honda C70, Coolster QG-214 X-M125, and Kawasaki KDX80. They are also intended for compatible 110cc, 125cc, and 140cc dirt bikes, pit bikes, and motocross bikes, as well as tires designed for street use.

• Suitable applications include motocross and enduro riding.
• Compatibility depends on the tire size fitted to the motorcycle.

What are the tubes made from, and what is included?

The set contains two motorcycle inner tubes made from butyl rubber. The material is used to provide impact absorption and puncture resistance, supporting a smoother ride in the intended applications. These are aftermarket replacement parts, and AR-PRO subjects its replacement parts and accessories to in-house testing for consistent quality.

• Quantity: two inner tubes.
• Check both the tire-size marking and the motorcycle application when choosing a replacement.

These AR-PRO tubes suit riders who need replacements for compatible 17-inch motorcycle tires, including dirt bikes, pit bikes, scooters, and mopeds. They are a size-specific option for tires marked 2.50/2.75-17 or 70/100-17, rather than a fit for every tire on those vehicle types.
