Rippin Moto Performance Duty Rear Motorcycle Inner Tube 18" — 2mm Natural Rubber, TR4 Valve

A 2mm-thick, 100% natural rubber rear motorcycle inner tube built for off-road riders who want improved puncture resistance and responsive handling. The Rippin Moto Performance Duty inner tube is made from pure natural rubber and sized for 18" rear dirt-bike wheels. It balances elasticity and strength to better absorb impacts than many thin OEM tubes while keeping rotational weight moderate. A factory-installed TR4 valve, cap, lock nut and conical washer simplify installation, making this tube a straightforward upgrade for motocross, enduro, pit bikes and modern electric dirt bikes.

How does this tube improve durability without adding heavy rotating mass?

The Performance Duty tube uses a 2mm wall thickness chosen to resist common off-road punctures and pinch flats while avoiding the inertia penalties of ultra-thick tubes. Natural rubber's inherent flexibility helps it deform around obstacles and recover quickly, reducing shock transmission and stress concentrations.

• 2mm thickness for added cut and pinch resistance compared with typical OEM tubes
• 100% natural rubber for superior elasticity and impact absorption
• Designed to limit added rotational weight, preserving acceleration and handling

Will this fit my bike and the tire sizes riders commonly use?

This inner tube fits a range of 18" rear tire dimensions used on off-road motorcycles. It was sized to be compatible with common cross and enduro tire profiles so you can replace worn factory tubes without altering ride geometry.

• Compatible sizes: 3.00-18, 3.25-18, 80/90-18, 90/80-18, 90/90-18, 90/100-18
• Intended for rear-wheel applications on motocross, enduro, pit bikes and e-motos
• Factory-installed TR4 valve for correct stem length and fit on 18" wheels

Is the valve assembly reliable for rough off-road use?

The tube ships with a reinforced TR4 valve stem plus a cap, lock nut and conical washer to secure the valve and reduce leaks from vibration. That hardware helps maintain air retention under demanding riding conditions and simplifies mounting through standard rim holes.

• TR4 valve stem designed for off-road wheel rims and routine inflation
• Includes valve cap, lock nut and conical washer for a sealed fit
• Factory installation reduces the chance of improper valve seating during replacement

How does this compare to heavier "heavy duty" tubes?

Rippin Moto's Performance Duty is a middle ground: thicker and more protective than thin OEM tubes, but lighter and more responsive than 3mm heavy-duty variants. Riders who want better everyday durability without a noticeably heavier feel typically choose Performance Duty.

• Performance Duty = 2mm wall for balanced protection and agility
• Heavy Duty option = 3mm wall for maximum puncture resistance and rugged terrain use
• Choose based on terrain severity and tolerance for added rotational mass

Who is this for? This tube is targeted at off-road riders who push their bikes in challenging terrain but still value nimble handling—motocross and enduro racers, weekend trail riders, pit bike users and electric dirt-bike owners who need a tube that copes with higher torque and added vehicle weight. If you want a dependable replacement that upgrades durability over thin factory tubes without the weight penalty of ultra-thick designs, the Rippin Moto Performance Duty 3.00/3.25-18 inner tube is a practical choice. Note: designed strictly for off-road use; consult your service guide for professional installation recommendations.
