Between the Norton Commando and the Triumph Bonneville, the Norton Commando was generally considered the faster bike in terms of raw performance and top speed during their respective production periods.
The Norton Commando, produced from the late 1960s to the mid-1970s, was known for its powerful parallel-twin engine and advanced suspension setup. It was capable of achieving impressive speeds for its time, often exceeding 100 mph (160 km/h). The Commando's engine design and performance characteristics made it a popular choice for riders seeking high-speed cruising and exhilarating acceleration.
On the other hand, the Triumph Bonneville, particularly in its classic iterations produced during the 1960s and early 1970s, was renowned for its smoothness, versatility, and all-around performance. While it wasn't as focused on top speed as the Norton Commando, the Bonneville still offered a satisfying combination of power and agility, making it a popular choice among riders looking for a well-rounded motorcycle.
It's worth noting that individual model variations, engine configurations, and specific production years can influence the performance characteristics of these bikes. Moreover, modifications and aftermarket enhancements can further enhance the speed and performance of both the Norton Commando and the Triumph Bonneville. Therefore, it's important to consider the specific model, engine size, and any modifications when comparing the performance of these vintage motorcycles.
