The KTM 660, particularly the KTM 660 SMC and 660 Enduro models, can reach a top speed of around 110 to 120 mph (177 to 193 km/h), depending on the specific model and conditions. This performance is attributed to its powerful single-cylinder engine, which delivers strong torque and acceleration. The bike's lightweight design enhances its agility and overall speed capabilities, making it popular for both street and off-road riding.
