Release date: June 1, 1971.

In 1971, the Honda Benly CB50 appeared as the successor model, which was given the title of "CB" for the first time in the 50cc class, is equipped with a newly designed vertical OHC engine on a newly developed diamond frame.

A classic lightweight sport model, Honda Benly CB50 has power performance that is easy to handle even at medium and low speeds, and has friendly styling. This new product is equipped with luxurious equipment for the first time in the lightweight class, and has further enhanced safety considerations such as a helmet holder and speed warning display.
With this, Honda's CB series (super sports series) has 11 classes of models ranging from 50cc to 750cc displacement, and we are able to respond to a wider range of customer requests.

1971 Honda Benly CB50 Main Features

For your safety

• Helmet holder... Adopted next to CB500. Even when you leave the car, you don't have to worry about carrying a helmet, and it is actively convenient to wear a helmet.
• Speedometer...At 30km/h or more, the display turns red to warn the user of overspeeding.
• Safe driving label: A slogan such as wearing a helmet is affixed to the tank.

Easy to handle and sporty

• Frame: A new diamond-shaped pipe frame has been designed to match the engine designed for 50cc super sports. Lightweight and highly rigid, it is suitable for light sports driving.
• Tachometer: This is the first equipment in the 50cc class that is essential for sports driving.
• Muffler: A megaphone type that emphasizes a sporty image. This is also my first time in this class.
• Handle: Semi-up type, easy to handle for anyone. Matches the seat for an excellent driving position.
• Even if the engine is in gear, the primary kick mechanism allows the engine to start immediately, making it easy to start.
• Three bright body colors (gold, orange, and white) are available.

Newly designed compact 4-stroke OHC upright engine

• Engine layout: The cam chain, oil pump, primary kick, etc., have adopted a highly reliable structure that is equivalent to that of a high-end model.
• Engine characteristics: Flat engine characteristics suitable for driving in urban areas, emphasizing smooth handling at medium and low speeds.
• Maintenability…By adopting the same separate camshaft holder as the CB750, maintainability has been improved.
• Mission... 5 stages. The shift fork shaft is a separate shaft to give a soft change feeling.

In addition, in consideration of customer safety, when the Benry CB50 was released, a campaign was held to present original helmets for purchasers of this model (from June 1st to August 31st). I will.

In this way, in order for all customers to ride safely and comfortably, we will actively promote the wearing of helmets together with the newly devised helmet holder.
