Yamaha YQ100 AEROX 2003 Parts & Accessories

First introduced in Europe in 1997, the original two-stroke Yamaha Aerox (YQ50 and YQ100) became a benchmark for high-performance sports scooters. Styled with aggressive race-replica bodywork and powered by liquid-cooled or air-cooled Minarelli engines, it earned a massive following among European moped riders and tuner communities. The 50 cc version was factory-restricted to 45 km/h to comply with European moped regulations, but its robust chassis and disc-brake setup made it one of the most popular platforms for aftermarket tuning and performance upgrades throughout its production run.
