KENDA 70/100-19 (250/275) SUPER TUFF TUBE

The Kenda Super Tuff is a heavy-duty motorcycle inner tube built for 19-inch wheels running 70/100-19, 2.50-19 or 2.75-19 tyres. As the name suggests, it uses a thicker-walled construction than a standard tube, which makes it a sensible upgrade wherever pinch flats and sharp trail debris are a regular hazard.

This size is most commonly a front fitment on big-wheel 85cc motocross and off-road machines, and on smaller trail and vintage bikes running narrow 19-inch rubber. It is a straightforward replacement or spare to carry in the toolbox, ute or race trailer.

Sold individually. Always confirm the size marked on your tyre sidewall before ordering.

Check the size marked on your tyre sidewall matches 70/100-19, 2.50-19 or 2.75-19 before fitting.
Dust the tube lightly with talcum powder before installation so it can move freely inside the tyre and does not chafe.
Inflate the tube just enough to hold its shape during fitting; a limp tube is easily pinched by tyre levers.
Use rim tape in good condition over the spoke nipples, and make sure the valve stem sits square to the rim before final inflation.
If your wheel uses rim locks, tighten them only after the tyre is seated and the tube is correctly positioned.
Set and check tyre pressures cold, following the pressures recommended by your motorcycle and tyre manufacturer; low pressures increase the risk of pinch flats and tube movement.
After the first ride on a new tube, recheck pressure and confirm the valve stem is still upright — a leaning stem indicates the tyre has rotated on the rim.
Store spare tubes loosely folded or rolled in their packaging, in a cool, dry place away from direct sunlight, fuel, oils and solvents.
Inspect the inside of the tyre and rim for spoke ends, grit or damage before fitting a new tube, and replace a damaged tube rather than relying on a patch for sustained riding.
