The Details

Youth R-Core Motocross Race Pants.
Made to Race.

High-performance motocross pants designed for durability, mobility, and consistent comfort in demanding riding conditions.

Product Details

These motocross race pants feature a supportive multi-panel chassis that balances flexibility and structure for aggressive riding. Abrasion-resistant materials help manage roost, slide impacts, and repeated use on technical tracks while maintaining a comfortable feel during practice or race days.

Performance & Fit

Stretch zones in key motion areas allow natural transitions between seated and standing riding positions. Ventilated panels assist with airflow and heat management in warm conditions, while the tapered lower leg integrates cleanly with boots to reduce bulk and bunching.

Materials & Construction

Built from durable synthetic fabrics with reinforced stitching, these pants are engineered to withstand frequent riding and high-contact areas such as the saddle and inner knee. The articulated knee design is compatible with guards and braces, making them suitable for motocross, off-road, and trail applications.

Size & Fit

Dialed In, Not Squeezed In.

Youth MX pants run smaller than adult sizing — when in doubt, measure your rider's waist and compare against the mens run below.

Size	Waist	Waist (cm)
28	28″	71 cm
30	30″	76 cm
32	32″	81 cm
34	34″	86 cm
36	36″	91 cm

Riding knee braces?

Size up one. The articulated knee clears guards, but braces need the extra room through the thigh and knee.

Between sizes?

Go up. MX pants ride at the natural waist with an adjustable closure — a size up cinches down, a size down doesn't stretch out.

Boot fit

The lower leg is tapered to slide inside your boots, not over them. No bunching at the buckles.
