OKO X-Treme Dirt Bike

The World’s Strongest Off-Road Moto/Bike Tube Tyre Sealant
Seals slits, snake bites/ pinch flats and holes like no other product
 Deals with slits and holes up to 7mm in mountain bikes: 9mm in off road motorbikes
Finish your ride when others fall by the wayside

Also recommended for mopeds and scooters that have inner tubes


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.

NEW 800 ml bottle deals with four 26” MTB or Cross Country tyres, where you need 160ml each for ultimate protection.

Simple fitting, using the valve core remover and filling tube supplied in every bottle cap.

NEW 5 Litre can is great for small bike workshops: it comes complete with the OKO 150ml Injector, for easy, accurate and rapid delivery.

25 litre drum is ideal for retailer and team service workshops: sold separately, the NEW heavy-duty all-alloy drum pump is a one-time purchase and can be rinsed out again and again for repeated use in filling tyres rapidly. It uses the unique OKO Bike drum pump with adjustable dosage, plus it has Schrader and Presta valve fittings.
