KENDA 300/325-16 (90/100) TR4 TUBE

A replacement motorcycle inner tube from Kenda, sized to suit 16-inch tube-type wheels running 3.00-16, 3.25-16 or 90/100-16 tyres. It is fitted with a TR4 straight metal valve stem, the common pattern for motorcycle rims where the valve hole sits perpendicular to the rim face.

Suited to riders replacing a punctured or perished tube, or keeping a spare in the workshop or trail kit. Sold individually.

Check the size printed on your tyre sidewall and confirm your rim uses a TR4 valve before ordering, as some wheels require an angled TR6 stem instead.

Confirm the tube size against the marking on your tyre sidewall, and check that your rim's valve hole suits a straight TR4 stem rather than an angled type.
Dust the tube lightly with talcum powder before fitting so it can settle inside the casing without bunching or chafing.
Inflate the tube just enough to hold its shape before installing it, which reduces the chance of trapping it under the bead.
Use tyre levers carefully and keep them clear of the tube to avoid pinch damage during fitting.
Make sure the valve stem sits square to the rim, not pulled to one side, and tighten any rim lock before final inflation.
If the wheel uses a rim lock or is run at low pressure off-road, keep the lock properly tensioned to stop the tyre rotating on the rim and tearing the valve stem out.
Check tyre pressure regularly with an accurate gauge and inflate to the pressure specified by your motorcycle or tyre manufacturer.
Fit a new rim tape or check the existing one for damage, as exposed spoke nipples will puncture the tube.
Store spare tubes in their packaging in a cool, dry place away from direct sunlight, fuels, oils and solvents, all of which degrade rubber.
Replace rather than repair a tube that has a tear near the valve base or multiple punctures, and treat any patch as a temporary measure.
