Introduced in 1965, the Honda CB-450 was Honda’s big bike. Affectionately known as the “Black Bomber", it was one of the first bikes offered to the public with dual overhead cams. Honda once again used real innovation and was thinking outside of the box with its unique torsion bar valve arrangement. Instead of valve springs, Honda used torsion bars to open and close their valves. Even with a four-speed transmission they became very popular for racing. Their unique tank with its chrome side panels made it stand out. This appears to be a well-executed restoration with 10,784 miles indicated.
