17 Inch inner tubes in standard, heavy duty and ultra heavy duty, from IRC, Vee Rubber and more. A 17 inch tube fits the rear of the big wheel minis and farm bikes (TTR230, CRF230F, AG200) and the front of some small wheel bikes.
Common sizes on this page: 70/100-17, 250/275-17 and 275/300-17. The tube size is the tyre size: read it off the sidewall and match the last number (the rim) and the width range on the tube.
Heavy duty tubes are 3 to 4mm thick and shrug off pinch flats on rocks and square edges; standard tubes are lighter and fine for motocross. Members pay the member price on every product in the store and get free standard shipping on orders over $10. Membership is $5 for the first month.

Read the size off the tyre sidewall, for example 80/100-21. The last number is the rim size and must match exactly; the width range on the tube (80/100 or 90/90) just has to cover the tyre. 70/100-17, 250/275-17 and 275/300-17 are the usual sizes here.
Heavy duty (3mm or more) for enduro, trail and rocks, where a pinch flat ends the day. Standard for motocross, where weight matters and the track is soft. Ultra heavy duty (4mm) for desert and hard enduro.
Not for a tube change. Check the rim tape covers every spoke nipple and the rim lock nut is tight; a loose rim lock is the usual reason a new tube fails straight away.
