Remembering the 1935 Cotton Racer 350

In the 1920s, Gloucester-based Cotton was unchallenged when it came to innovating the best racing motorcycles. The founder of this company, Frank Willoughby Cotton, designed these bike chains with smooth frames that facilitated their speed and patented them to begin a series of the best vintage motorcycles remembered today. The 1935 Cotton Racer 350 is part of this range. This article will take a look at this adorable bike that has captivated motorcycle enthusiasts for decades. According to Antique Motorcycles, what today’s MotoGP fans are witnessing began in the 1920s, fans were treated to special moments in this sporting activity. In the early 1920s, the designer of the 1935 Cotton Racer 350 was a diehard fan of motorcycle racing, and that was what motivated them to develop this series-winning motorcycle.


After the bike was released in the market, it won a series of races thanks to its unique characteristics, unmatched by other competing companies. Frank W Cotton featured four straight tubes in the design of the bike, which fitted them to move from the steering head to the wheel axle. The motorcycle was increased with the help of consecutive stays, which supported the motor and the gearbox of the motorcycle. This innovation resulted in a unique masterpiece bike that was stiff for any racing terrain with a lightweight frame to gain more speed than motorcycles created using diamond-type frames, which many bicycle developers were using at the time to make their racing bikes. According to FichasMotor, there were small companies producing racing bikes before 1935 Cotton Racer 350 was invented. At the time, the materials used to create motorcycles were not as advanced as those used to make MotoGP racing bikes today. Like the rest of the small independent firms that existed then. Mr. Cotton used most of the materials available to produce this vintage bike. Cotton relied on proprietary engines, Blackburne, and primarily JAP among the parts. The area in which he aged other manufacturers was how he created the bike frame for the 1935 Cotton Racer 350 masterpiece, which gave the bike more advantage during races. When the 1935 Cotton Racer 350 was introduced to motorcycle competition, the rest of the manufacturers bowed. This bike after being introduced in the sports category, the first model of Cotton Racer 350 became a revelation and spoke on everyone’s lips in 1935, that’s why it is called the 1935 Cotton Racer 350, a vintage motorcycle that has a lasted a generation of motorcycles turning over 87 years.

Legendary Stanley Woods entered the record books when he made his debut in Isle of Man TT competition in 1922 with 1935 Cotton Racer 350. He set a new speed record in a junior race the following year. During the racing events of the 1920s countless events motorcycle sports enthusiasts were treated with special moments with the victories of the 1935 Cotton Racer 350. This motorcycle did not miss out on a podium place in any international event during this period. For example, in the Man TT race in 1926, entrants who rode 1935 Cotton Racer 350s in the lightweight 250 class took the top three podium spots. Other renowned motorcycle racers who graced international competition with this bike include Jack Squirrel in the 1980s and the late Rupert Leveson in Vintage events in the 250cc and 350cc classes. If you want to see this bike in person, you can visit Sammy’s famous museum in New Milton, Hampshire. It was kept there to keep his memory alive for motorcycle racing enthusiasts. When the 1935 Cotton Racer 350 hit the market, it was selling for 59,684 pounds. Now let’s take a look at the features of this record-breaking vintage bike.

Body parts as a whole

Generally, the 1935 Cotton Racer 350 was designed for sport racing. It has a displacement of 350.00cc. The body part is what sets this bike apart. The cotton company used quality strong materials to ensure that the bike was stable during races and gained more speed. The bike is designed to give the rider a streamlined body while racing. Therefore, the wind cannot reduce the pace of the bike when accelerating.

Engine and gearbox

The 1935 Cotton Racer 350 ran on a single-cylinder, 4-stroke engine. This means that the bike can perform four strokes when hitting the road. The four strokes are suction, exhaust, compression and expansion. On the first stroke, cool air or a mixture of air and fuel enters the motorcycle’s engine, allowing the piston to move from top dead center (TDC) to bottom dead center (BDC). In the second stroke, known as the compression stroke, the new load inside the engine will compress and push the piston away from BDC to TDC.

The third hit (expanding hit) is known as the power hit. In this stroke, compression occurs. The resulting combustion generates high pressure hot gases found inside the cylinder – the all important event of this pressure in the movement of the piston from TDC to BDC. The available hot gases are expanded from TDC to PMB during this process. The final stroke is known as the exhaust stroke. Typically, when a cycle continues to run ideally, it must release heat to engine parts. Available hot gases will be expelled from the cylinder as the piston moves from BDC to TDC. The above four stroke of the 1935 Cotton Racer 350 engine creates a heat engine cycle. So, by allowing the motor to have two full revolutions, the motorcycle will accelerate with good speed.

The 1935 Cotton Racer 350 engine runs with a carburetor intake. The valves regulate fuel in an orderly fashion based on how the rider will engage gear and throttle as they pick up speed during competition. Fuel consumption is controlled by overhead valves positioned on top of the piston. This allows the engine’s camshaft to move the valves through the tappet, rocker arms and tappets. When the four strokes start, it allows combustion to occur smoothly by allowing the air-fuel mixture to distribute itself evenly to all parts of the combustion chamber. This racing bike is equipped with a single saddle for the single rider because its vocation is racing. All in all, we will remember the 1935 Cotton Racer 350 with a fresh memory it created during the time it dominated motorcycle racing events and vintage bike events. Therefore, as we go back in history for people who broke motorsport records, a special mention of this bike has to be there.
