Motion Pro Lite Rim Lock II — nylon tubed rim lock, 2.15 size, ultra-light & impact-resistant

If you run tubed tires on your dirt bike, enduro, or dual‑sport machine and want dependable bead retention without the added heft of traditional metal hardware, the Motion Pro Lite Rim Lock II is engineered for exactly that. It pairs a molded nylon body with the new Motion Pro aluminum LiteLoc rim locknut and beveled washer to create a low‑mass assembly that resists shocks and protects the inner tube from abrasion and heat build‑up.

How does the Lite Rim Lock II keep the tire from slipping under low pressure?

The rim lock uses angled, tapered ribs that bite into the tire bead and hold it firmly against the rim. The contoured shape concentrates clamping force where it’s most effective while avoiding sharp edges that could abrade the tube.

• Angled and tapered ribs lock the bead to the rim securely.
• Contoured profile spreads pressure evenly to prevent tube pinching.
• Beveled washer helps align the assembly for consistent clamping.

What makes this rim lock lighter and more impact resistant than aluminum options?

Motion Pro designed the Lite Rim Lock II as a single molded piece from a proprietary high‑strength nylon composite. That material choice delivers substantial weight savings while absorbing and distributing impact forces better than brittle cast aluminum.

• One‑piece molded construction reduces weak joints and stress risers.
• Testing shows 10–20% greater strength and higher impact resistance versus cast aluminum alternatives.
• Weighs only 68 g for 2.15 size and 35 g for 1.60 size—roughly half the weight of many metal rim locks.

What hardware is included and how does it fit my wheel?

Each kit pairs the molded nylon body with Motion Pro’s aluminum LiteLoc locknut and a beveled washer for a compact, reliable package. The included components are designed for standard off‑road rims and tubed tire setups, making installation straightforward for most dirt and dual‑sport wheels.

• Includes Motion Pro aluminum LiteLoc rim locknut and beveled washer.
• Available sizes (e.g., 2.15 and 1.60) match common off‑road tire widths and rim dimensions.
• Low profile design clears spokes and brake components on typical off‑road wheels.

Why choose the Lite Rim Lock II for trail and race use?

Its combination of low weight, improved impact resistance, and a tube‑friendly shape makes the Lite Rim Lock II a smart choice for riders who push their machines across rough terrain. The design lowers rotating mass and reduces the risk of tube damage from the rim lock itself while maintaining strong bead retention at low pressures.

• Helps reduce rotational weight for better handling and acceleration.
• Shape protects the inner tube from abrasion and heat during hard use.
• Durable composite tolerates impacts common in off‑road riding.

Who is this product for? The Motion Pro Lite Rim Lock II is aimed at off‑road riders—motocross, enduro, trail, and dual‑sport enthusiasts—who use tubed tires and want a lighter, tougher rim lock than conventional cast aluminum options. It’s also a good fit for racers and riders lowering tire pressure for traction who need reliable bead retention without extra weight. Note: installation and compatibility depend on rim and tire combination; choose the correct size for your rim width.
