Overview

Introducing the 1986 Aprilia RX 250: A Cross-Motocross Icon Step back in time to 1986, when the motorcycle world was abuzz with the arrival of the Aprilia RX 250—an exhilarating entry into the cross-motocross category. Designed for adrenaline enthusiasts and off-road adventurers, this agile machine was tailored for both competitive riders and casual trail blazers. The RX 250 made its mark by combining cutting-edge technology with European flair, establishing itself as a favorite among those looking to tackle dirt tracks and rugged terrains alike. With its lightweight design and spirited performance, the RX 250 became a symbol of freedom and adventure in the motocross community. At the heart of the Aprilia RX 250 lies a potent 246cc single-cylinder two-stroke engine, capable of producing an impressive 47 horsepower at 8,000 RPM. This robust powerplant, paired with a 5-speed gearbox, translates into exhilarating acceleration and top speeds of 120 km/h (about 74.6 mph). The high compression ratio of 14.0:1, combined with liquid cooling, ensures that the engine performs optimally in even the most demanding conditions. Riders can expect a thrilling experience as they navigate challenging trails, with the RX 250's lightweight chassis, weighing in at just 100 kg (220.5 lbs), making it incredibly nimble and responsive. Whether you're climbing steep inclines or darting through tight corners, this motorcycle delivers a dynamic riding experience that keeps you engaged. Key features of the RX 250 include a single disc front brake for effective stopping power and an expanding brake at the rear, ensuring riders can confidently manage their speed on various terrains. The motorcycle's fuel tank capacity of 8.5 liters (2.25 gallons) provides adequate range for those extended rides, while the thoughtfully designed suspension system enhances comfort and control over uneven surfaces. The bore and stroke measurements of 72.0 x 61.0 mm give the engine a balanced power delivery, making it perfect for both competitive races and leisurely rides. With its distinctive styling and performance-oriented design, the Aprilia RX 250 is not just a motorcycle; it's a ticket to adventure. **
