The 1947 Indian Bonneville, hailing from United States, by contrast offered 1200cc of SV V-twin power, delivering 40hp at 4800rpm. Tipping the scales at 248.0kg (547 lbs) with a top speed of 140km/h (87 mph), it offered a distinct riding experience. 1940s motorcycles, especially military-era models, hold strong collector interest with values reflecting their historical significance.

The Verdict
These two machines serve fundamentally different purposes. The 1947 Norton International is built for outright circuit racing performance, while the 1947 Indian Bonneville targets all-round versatility and everyday riding. On paper, the 1947 Indian Bonneville's 40hp trumps the 1947 Norton International's 29hp, but raw numbers don't tell the whole story in such different segments. Choose the 1947 Norton International if you value outright circuit racing performance; pick the 1947 Indian Bonneville for all-round versatility and everyday riding. Parts availability is difficult for the 1947 Norton International and very difficult for the 1947 Indian Bonneville — an important factor for any restoration project.
