450 Motor

Introduction

The 450 motor refers to a range of internal combustion engines with a displacement of approximately 449 cubic centimeters (cc). These engines are commonly used in small to medium-sized vehicles, including motorcycles, scooters, and cars.

The term "450" is often associated with the Honda CM400i motorcycle engine, which was introduced in the early 1980s. This engine design became a benchmark for its time and influenced the development of similar engines in other manufacturers' models.

History/Background

The history of the 450 motor dates back to the late 1960s and early 1970s, when motorcycle manufacturers began experimenting with smaller displacement engines. One of the pioneers was Honda, which introduced its first 400cc engine in the CM125R model in 1969.

Over the next decade, other manufacturers followed suit, introducing their own versions of small-displacement engines. The 450 motor emerged as a compromise between performance and fuel efficiency, offering a balance between power and economy.

Key Concepts
