There has been great technological innovations in terms of the design and production of motorcycle engines. Larger motorcycle manufactures such as Honda, Suzuki, and Yamaha continue to put large amounts of money into research and development in order to create the top performing motorcycle engines.
Almost all car manufacturers will tell you that the leading edge of engine development is in motorcycles instead of aircraft or automobiles. Often the innovations applied to motorcycle engines migrate over the car engines. When designing new motorcycle engines the goal is always better combustion. One of the newest innovations is the use of more than four valves for each cylinder to produce a greater flow area.
The movement of the motorcycle engine from the two valve models to the four valve models was all geared toward creating better combustion.
When Honda first introduced the four valve engine back in the 1960s it allowed for the use of narrow valve angles and combustion chambers which where shallow which along with a spark plug gave you good combustion.
In the early 1980s Yamaha began to look beyond the standard four valve engine for methods of using new head and valve configurations to improve combustion. Some of the designs they looked used seven cylinders per valve. This design featured four intake valves and three exhaust valves.
They finally found the performance they were after using five valves per cylinder. This design allows for an extra intake valve which allows for better air flow during low to medium valve lifts.
This is the way that most engines are operated on a regular basis. One of the biggest and most advanced manufacturers of motorcycle engines in North America has to be Honda.
They have built a state of the art plant with more than a million square feet which cranks out more than half a million engines each year. They combine the most advanced manufacturing techniques with state of the art engine design.
