From pioneering performance to groundbreaking design and innovation that brought motorcycles to the masses, check out these top picks for the most influential motorcycles ever built.
Every motorcycle aficionado has ideas when it comes to naming the most important bikes ever built, and Somer Hooker is no exception. Hooker is a vintage bike broker with over 25 years in the business and he is also Chief Judge at the Celebration of the Motorcycle event in Del Mar, California. The HVA worked with Hooker to modify the current Preservation Award judging criteria to recognize preservation-class motorcycles.
The HVA Motorcycle Preservation Award will be presented at two shows in 2013. Click here to check out the list of judging criteria. But before you do, take a look at Hooker’s shortlist of the five most important motorcycles from the last 70 years.
Honda C-100 Super Cub

Claim to Fame: A reliable, excellent entry-level bike for neophytes that wouldn’t break the bank, the Honda C-100 Super Cub made owning a motorcycle possible for millions of new riders.
Since its debut in 1959, millions were (and still are) manufactured. This was Honda’s first major thrust into the marketplace—a small, simple utilitarian motorcycle that was easy to ride and hard to break. Motorcycles had a “dirty” image in the late `50s and early `60s, a problem Honda overcame through a brilliant marketing campaign with a crafty pitch: "You meet the nicest people on a Honda." Parents were known to come into showrooms and say, “Oh, we don’t want a motorcycle, we want a Honda!” This bike was responsible for putting millions of people onto motorcycles.
Honda CB 750 Four

Claim to Fame: With amenities taken for granted today, the CB 750 Four marked an industry shift into the modern age.
In 1969, the British motorcycle industry reigned supreme. Known for attractive but unreliable bikes with dicey electrics and a tendency to leak oil, British motorcycles of the era were also fitted with drum-style brakes and a manual kick-start. Suddenly, Honda introduced a four-cylinder motorcycle with electric start, disc brakes and a horizontally split crankcase that wouldn’t leak. Hondas were also dead reliable. Within five years most of the British manufacturers were on their way out. This bike was also the basis for a large aftermarket speed equipment industry, just as the flathead Ford and small-block Chevy spawned similar activity.
Vincent Black Shadow

Claim to Fame: One of the first motorcycles that launched the age of the superbike, this record-breaking motorcycle was a new model for brilliant engineering and performance.
After WWII, the Vincent-HRD Works in Stevenage, England, pretty much hand built large, light V-twins that became the basis of numerous world-record runs. The most famous was the John Edgar/Rollie Free bike that, in 1948, ran over 150 mph on the Bonneville Salt Flats with Free stretched out on the tank dressed in nothing but a Speedo, helmet and oversized tennis shoes. To this day, Vincent engines are still used as the heart of some land-speed record attempts.
Ducati 750SS

Claim to Fame: This motorcycle helped propel a relatively unknown Bologna factory into mainstream motorcycling and the world of the superbike.
Until 1972, Ducati was a small but significant manufacturer of single-cylinder motorcycles. They then produced a V-twin motorcycle (technically an L-shaped configuration) with desmodromic valves. Instead of being closed by springs, the valves are opened and closed mechanically. It was introduced at Imola race track in Italy in 1972 and took first and second place. This vaulted Ducati into the mainstream as a major motorcycle manufacturer and competitor on the track, a spot it still holds today.
1915 Harley-Davidson V-Twin

Claim to Fame: With a three-speed transmission and V-twin engine, it became the benchmark for motorcycling until WWII.
Harley briefly released their V-twin in 1909, but it had so many problems that engineers were forced back to the drawing board. Two years later, the V-twin became fairly reliable. In 1913, the company switched to a two-speed transmission and by 1915 they had developed a three-speed transmission. At this point, the bike became an excellent motorcycle for touring. Recently, in the Cannonball Rally for 1915-and-earlier motorcycles, 1915 Twins were the weapon of choice for contenders.
