O'NEAL Pump Gun MX Knee Guard — Carbon Look Black, Ventilated Hinged Pair (One Size)

O'NEAL's Pump Gun MX Knee Guard (carbon look) is a ventilated, hinged motocross knee protector sold as a pair that balances impact resistance with flexible motion.

Built for off-road riders who need dependable coverage without bulk, this knee guard pairs a hard, injection-molded outer shell with a shaped foam interior and articulated pivot to follow your leg's movement. The carbon-look finish gives a modern aesthetic while the design keeps pads positioned during aggressive riding and minor slides. Sold left and right, the guards include elastic and Velcro straps for a snug fit and extra padding to cover hardware points.

How does the hinged pivot design affect mobility?

The hinge mechanism lets the guard articulate with your knee, reducing resistance when you pedal, stand, or bend. Rather than forcing a fixed position, the pivot follows natural motion so you retain control and comfort during technical maneuvers.

• Articulated hinge for fluid bending
• Less restriction while standing on pegs or sprinting
• Improved fit through active range of motion

What protective materials and construction are used?

The outer shell is made from high-impact injection-molded plastic engineered to absorb and distribute force. Inside, pre-formed foam is contoured to the knee to cushion contact and keep the plate stable under load.

• High-impact injection-molded outer shell
• Shaped foam liner for contact comfort
• Cushioned hardware covers to prevent bike damage and rider irritation

Will these stay secure during a ride or crash?

Three elastic straps with Velcro closure provide a customizable, demo-friendly fastening system that holds the guards in place under typical off-road forces. Padding over rivets and bolts reduces snagging and protects both rider and bike when contact occurs.

• Triple elastic Velcro straps for adjustable fit
• Padded rivets and bolts to prevent abrasion and damage
• Low-profile inner bolt allows safe contact with bike surfaces

How breathable and wearable are these for long rides?

Ventilation and a lightweight build reduce heat buildup so you can stay comfortable on long trails. The slim profile and contoured foam also help avoid bunching under pants or shifting during extended sessions.

• Lightweight construction minimizes fatigue
• Vent ports and open design for airflow
• Pre-formed foam reduces pressure points during long rides

Who is this for? These O'NEAL Pump Gun MX Knee Guards suit riders who want robust, motocross-grade coverage without sacrificing freedom of movement. Ideal for trail, enduro, and motocross riders who prefer a streamlined guard with reliable impact protection and easy on/off during quick pit adjustments. They work well for riders who need a one-size option with a secure strap system and a contemporary carbon-look finish.
