Alpinestars Racer Lone Jersey

Racer MX jersey in the Lone graphic

The Racer Lone Jersey is Alpinestars' Racer motocross jersey in the low-key Lone colourways, one of them plain black. Racer sits below Techstar and Supertech, so it's the everyday jersey for club racing, practice and trail riding: a lightweight, durable multi-material polyfabric body that wicks sweat, mesh panels on the sides of the torso and stretch mesh under the arms for airflow, and overlock stitching through every seam.

Sizing and fit

Sizes S to 2XL in two colourways: Black and Gray/Purple. Ergonomic pre-curved race fit, so it sits close through the body; if you wear a chest protector or body armour underneath, most riders go up a size. Extended rear hem to stay tucked, fitted wrist cuffs to sit under gloves, and an open, relaxed stretch collar.

Match it up

Made for the Racer Lone Pants in the same colourways, or the perforated Racer Air Lone Pants for summer. Finish the kit with Radar Gloves or Full Bore v2 Gloves, and kids can match in the Youth Fluid Lone Jersey.

The Racer Lone Jersey is a performance-driven MX jersey built for motocross riders who need lightweight comfort, mobility, and lasting durability across demanding off-road sessions. Constructed with advanced multi-material polyfabric, moisture-wicking ventilation, and strategically placed stretch mesh panels, it delivers an ergonomic pre-curved fit that keeps movement fluid and comfort high on the bike.

• Race fit: Ergonomic pre-curved patterning supports a close, performance-oriented feel that moves naturally with the rider on the bike.
• Moisture-wicking comfort: Advanced fabric performance helps manage sweat buildup to keep the jersey feeling comfortable through long motos and repeated sessions.

• Breathable stretch mesh inserts positioned on the undersides of the arms.
• Overlock stitching throughout the garment for added seam durability.
• Stretch collar neck construction with an open, relaxed collar profile.
