Vehicle Information
KTM 125 Duke Motorcycle - Street (2020-2021)
The KTM 125 Duke (2020-2021) is a dynamic and agile naked street bike, perfect for urban commuting and spirited riding. Powered by a 124.7 cc liquid-cooled, single-cylinder engine delivering 15 horsepower, it offers an exciting entry into the world of motorcycling. Known for its sharp styling and lightweight design, the 125 Duke provides a thrilling experience for new riders and enthusiasts alike. While maintaining its core engine, the 2021 model received a significant update, often described as a cosmetic overhaul, aligning its aesthetics with larger Duke siblings. Key changes included a redesigned headlamp, a sharper fuel tank with increased capacity from 11 to 13.5 litres, and a new split-trellis frame replacing the older chassis. The engine was also updated for Euro5 compliance. Trim levels remained consistent, primarily differing in color schemes. Q: Is this product compatible with my 2020 or 2021 KTM 125 Duke?
