| Comment | The sound you're probably thinking about is high RPM.
[Here's](https://youtu.be/b0ZjDSn2jD0?t=50) a 250cc Honda motorcycle from the 80s that revs to 20k RPM. As the video shows though, it'll hit the redline doing 30mph.
Similarly, I own a Street Triple R and it revs to [12,500](https://youtu.be/hDjFtb0ygus?t=19).
However, RPM isn't indicative of performance. It's also kind of subjective since the street triple R, when hearing it in person, has a distinctive whine and whistle sound from the straight gears and in-line 3.
A boxer engine will sound gruntier. A harley davidson will sound kind of [ugly](https://youtu.be/XeuXShFIgyc?t=215).
Comes down to personal taste. |
