I replaced my tube for a desert race in eastern WA. The course is littered with nasty rocks. Made it 100 miles bashing through the rocks.
IRC Heavy Duty tubes are designed and constructed to offer great performance in the most extreme motorcycle riding conditions. IRC heavy duty tubes are made 3 mm thick and puncture resistant, making them durable to better handle extreme and aggressive use. For maximum performance and durability, IRC tubes are made of a blend of both natural and butyl rubber.
