Product Description
Warp 9 2mm Natural Rubber Motorcycle Tubes
Our own tubes, built to our spec for spoked dirt bike, supermoto and e-moto wheels. Every tube has a 2mm natural rubber wall and a TR-4 valve stem. That's the wall thickness most brands only offer in their heavy-duty line.
What makes them different
- 2mm natural rubber wall. Thicker than a standard tube for better puncture resistance, pinch-flat protection and heat resistance.
- TR-4 valve stem topped with a black Warp 9 valve cap.
- Size printed on the tube. The Warp 9 logo and tube size are printed right on the rubber, so you know what's in the wheel without guessing.
- Color-coded bags. Each tube comes in its own bag, color coded by size, with the size, part number and barcode on the label. Easy to grab the right one off the shelf.
Warp 9 vs. Them
| Warp 9 | Brand A | Brand B | |
|---|---|---|---|
| Wall thickness | 2 mm | 2 mm | 3 mm |
| 17" street and supermoto sizes (110/70, 140/70) | Yes | No | No |
| Price | $10 | $14 to $17 | $36 |
A heavy-duty 2mm wall for a lot less, in the 17" street and supermoto sizes the big brands skip. Plus every Warp 9 tube has its size printed on the rubber, comes in a color-coded bag and wears a Warp 9 valve cap.

Good to know
- Match the tube to the tire, not the bike: a 19" front and a 19" rear take different tubes.
- Fit a fresh rim strip over the spoke nipples when you change a tube, and add rim locks if you run low pressure off-road.
