The 2023 Racer Semi Jersey from Alpinestars slots into the brand’s entry-level MX range with a clear mission: solid riding performance at a price that won’t stop you getting out on the bike. The main chassis uses an advanced poly-fabric engineered specifically for moisture-wicking, so when the session gets tough and the temperature rises, the jersey is actively working to keep you dry and comfortable rather than just sitting there.
Mechanical stretch is built into the fabric itself rather than relying purely on clever cutting. The result is a jersey that gives way where you need it, whether that’s crouching over the bars on a downhill section or stretching out through a rough corner. The stretch collar and wrist cuffs complement this, providing a comfortable, close fit around the key contact points without gripping or restricting.
Fit-wise, Alpinestars have thought about what actually happens on a bike. The jersey is cut longer in the rear, maintaining coverage when you’re in the riding position rather than leaving a gap between kit and trousers. Wrist cuffs are fitted to work neatly with gloves. Simple design decisions, but they make the riding experience noticeably better.
The Racer Semi is built to pair with the Racer Pants and Gloves, and the fade-resistant sublimated graphics stay looking fresh through regular washing.
The Racer Semi suits riders at the beginner and intermediate end of the MX spectrum who want to ride in proper branded kit without overcommitting on budget. It’s a strong choice if you’re building a first complete kit setup, want a spare jersey for practice days, or are upgrading from unbranded gear for the first time. Young riders progressing through junior MX classes will also find it a natural fit.
