Exhaust Sound

[skygazer6033]

Fully agree Mark. Years ago I bought an early 70's CB750. The previous owner had replaced the stock mufflers with 4 shorties that were LOUD. I rode it from Ft. Benning, Ga. to Lincolnton, NC and was totally exhausted. Took about a week for the ringing in my ears to go away. Miserable trip.

A cb750 was my very first hot rod project as a kid.
I messed that bike up pretty bad and learned the hard way..lol
Went after top end hp....on the open road on a good day it was crazy fast. In traffic it was a hand full...hard to start. Ran like a peaky two stroke. Had to keep the rpms up.and had drum breaks.
Every motor build after than one was built for low end torque. And hp off idle and up. any motor build that went down a public street anyway.
Suppose what a learned was a street machine does not operate at redline but a few select times when I am being stupid.
I love being the fastest guy up to the speed limit. Or stoplight to stoplight.
I dont need to go 200mph....lol

My CB750 is a Japanese home market version, with a very quiet twin silencer system. It's the only bike I've ever owned where I can hear tyre noise! I think the noisiest thing on it is the quiet "clonk" of the gear change. Having had old BSAs running high compression (12.5 to one in one case) on a straight through pipe and reverse cone megaphone, I'm grateful that it's so quiet. Far more enjoyable to ride than a noisy bike.

The only bike that sounds good loud is an air-cooled, dry-clutched Ducati.

--In my opinion.

Try riding one for any length of time versus a quieter bike and see how you feel after 8 hrs or so in the saddle. Sound and vibration are exhausting. Nevertheless different strokes for different folks. Some like it loud and obnoxious, others like it quiet and serene.

8 hours in the saddle is totally out of the question when you get to my age, hell my attention span gets exhausting at about the 5 minute mark.

Regrettably, my sandcast '69 750 has made her voyage back to Japan. Honda has her now and I understand she will be returned to her former glory and will rest peacefully in their museum. I will miss her!

Fun fact: The pistons in the Harley-Davidson TC103 engine are larger in diameter than those in the LT1 and LT4 engines used in the C7 Corvette.

103 cubic inches = 1690 cubic centimeters, or almost 2 Elio engines. THAT is how they can be loud.

I've been told the pistons in my Suzuki M109R are bigger than those in a Chevy 454...those TC103 pistons are cute!

Not a big Harley fan myself but I have to admit they have the best sound of any bike.

You've obviously never heard a V-Max with aftermarket pipes...they sound like a top fuel funny car...to me loud Harleys sound like a tractor with straight pipes...

Grampi,
1. FYI, a tractor only has one pipe, so it would have to be two tractors.
2. I've heard a VMax, sounds more like a fart in a stove pipe, IMHO
3. Talk to me when Yamaha or Suzuki has been around for 112 years.
4. Last but not least, I'm not terribly impressed with racers that can only do something for ten seconds at a time!

Boy this ought to sufficiently stir the pot on many levels.

Generalizing can get ya in trouble, Dusty.
