I guess kind of the opposite of that clip with big engines, but I had to put these here because I love listening to them. The CBR 250RR is the best sounding production bike I know of. I don't think it would be possible to ride it anywhere without hearing it hit 20,000RPM at least once during the trip.
...And I can't leave out the older F1 engines.

Brent, you, like me, can appreciate some I.C. porn. Intoxicating. The 250 RR doesn't even sound like a 2t but it is sweet indeed! I miss those screaming F1 engines. To ride one of those 250 RRs would be euphoric.  |

There used to be a company, Nuak international in Ontario, but it looks like they no longer exist  |

Well, I started to say 4-5000 rpm but knew 3k at least to be safe. Too lazy to search it out.  |
