🔧 Honda CB Inline-Four Engine Heritage
The Honda CB750 of 1969 was the first mass-produced four-cylinder motorcycle — a 736cc SOHC inline-four with a 90 hp potential that made every existing British twin obsolete overnight. Soichiro Honda called it the project that would prove Japan could build world-class motorcycles. The same philosophy of the high-revving, smooth, reliable inline-four has been carried forward in the 1992 CBR900RR Fireblade (893cc) and the 2023 CB750 Hornet (755cc). Three generations, 55 years, same fundamental concept.
