  1. It is a horizontally opposed engine and, because it is made from aluminum alloy, it is light and compact and has good cooling performance. 
  2. Through designing a combustion chamber with high compression ratio and mechanical octane value, the engine has high output and high performance.
  3. The engine is designed to provide excellent durability.
  4. Fuel economy is good thanks to the high compression ratio and so on.
  5. Since the engine is horizontally opposed, it has good balance. Because it has no cooling fans and so on, it generates little vibration and noise and is quiet. 
  6. Since the engine is made of aluminum and has a new type combustion chamber with high mechanical octane value, it can use regular gasoline.
