NEW X-Treme Dirt Bike is a genuine step forward in tubed tyre sealant performance – a real breakthrough product that fights bigger holes and even slits.

If it’s strong enough for enduro motorbikes (which it most certainly is), you can be sure it’s stronger than any other bicycle tube sealant out there…

Designed for the needs of off-road competitors and weekend riders, it is the difference between making it home and being left stranded by a ‘snake bite’/ pinch flat.

It has been tested in the most demanding trial, enduro, motocross events; and MTB/XC, downhill, and other bike races; and has been the difference between winners and losers.

One 800 ml bottle will protect both a motorbike rider’s tyres, with enough to spare – or two sets of mountainbike tyres.

Like OKO Puncture Free, it also works for full UST bike wheel/tyre tubeless set-ups in the case of those who will be putting their bikes through extreme tests.

But we recommend you use OKO Magic Milk if you are using ‘tubeless ready’ tyres.

(‘Tubeless Ready’ tyres require rim tape, and OKO Magic Milk™ sealant: check the compatibility of your proposed rim and tyre combination before attempting).

For mopeds and scooters with inner tubes, use 250ml in front and rear tyres.
