Motocross vs. Supercross: An Overview

Motocross traces its roots to motorcycle trial competitions in the UK, evolving into the first-known scramble race in 1924. The sport gained traction in the 1930s, notably in Britain, with company teams like BSA, Rudge, and Norton leading the way. In 1948, the first motocross race in a stadium set the stage for Supercross.

The FIM’s 1952 European Championship (later becoming a World Championship) featured a 500cc formula. The 1960s marked the dominance of 2-stroke engines, while Motocross reached the US in 1966, bolstered by Japanese manufacturers challenging European dominance. The 1970s to 1990s brought American success and Japanese technological advancements in engine cooling and suspension to the fore of Motocross.

Conversely, Supercross originated as a stadium-focused variant of Motocross, debuting in 1972 at the Los Angeles Memorial Coliseum. The AMA SX Championship commenced the same year, showcasing purpose-built, stadium-centric motocross events. In the 1980s, Supercross became a distinct discipline with separate championships. In 2022, the World Supercross Championship became independent from the AMA series.

Some attributes that make Supercross distinct are its racing environment and riding season. Known for shorter straights and tighter turns, SX tracks differ from traditional motocross layouts and are often hosted in professional stadiums. Also, the supercross season unfolds during winter, and spring, held across various US cities.

Racing Season and Championships

The motocross season typically spans from late winter to early fall, with events distributed across various locations globally. Key events include international races and national championships in different countries. Below are some of the most illustrious of these competitions:
