Overview

Introducing the 2003 KTM EXC 525—a true titan in the world of enduro motorcycles. Recognized for its prowess in off-road racing and trail riding, the EXC 525 is engineered to tackle the most rugged terrains with confidence. As part of KTM’s celebrated EXC lineup, this model exemplifies the brand's commitment to producing high-performance machines that resonate with both competitive riders and off-road adventurers alike. With a robust single-cylinder engine and a lightweight frame, the EXC 525 is not only a powerful contender but also a nimble companion for those who seek thrill beyond the asphalt. At the heart of the EXC 525 lies a formidable 510.4cc four-stroke engine, delivering an exhilarating 61 horsepower at 8,000 RPM and a torque of 61 Nm. This powerhouse is mated to a smooth 6-speed gearbox, allowing for seamless power delivery whether you're navigating through tight trails or blasting down open fire roads. With a top speed of 180 km/h (111.8 mph), it offers exhilarating performance that is hard to match in its class. The liquid cooling system and a high compression ratio of 11.0:1 ensure that the engine maintains optimal operating temperatures even under demanding conditions, while the precision-engineered Keihin 39 mm carburetor provides responsive throttle control—essential for those hairpin turns and steep climbs that define off-road riding. The EXC 525 is packed with features that elevate your riding experience. The CrMo frame combines strength and agility, providing stability while keeping the bike light enough for agile maneuvering. Its suspension system is finely tuned to absorb the toughest bumps, ensuring that you can ride longer and harder without fatigue. With both electric and kick start options, you’ll never be left stranded, and the generous fuel capacity of 8.5 liters (2.25 gallons) allows you to venture deeper into the wilderness without constantly worrying about refueling. The bike's advanced CDI ignition system ensures reliable starts and optimal engine performance, making it an ideal choice for both seasoned riders and those new to the off-road scene. **
