Best Sounding Dirt Bike :D

As far as sound, a crisp two stroke is awesome. 125s are fantastic but a 500 ridden by a master is unreal.
Seems appropriate for a Danny Hammel tribute.

For me probably a well tuned Kx500 with a nice FMF pipe on it.

As far as four strokes go, Barcias MEC privateer CRF450 sounded nasty after Twisted Developments did work on it.

Both types sound sick , factory 450 sounds badazz

I've never heard it but I'd have to guess hearing Jonny'O on the twin cylinder HRC 125 would pretty much end the "What's the meaning of life?" question...

Yamaha banshee 350 two stroke.

I have a few....
As far as a mini goes, any Supermini Suzuki built by R&D during the 80's.
125, Stew's 02 KX 125 blasting around Unadilla sounded so strong, and healthy. Man he pissed Reed off that day....
RC's RM 250 had a sound all it's own. Really sounded great wound tight.....
And lastly, an HRC works 500 from 84, or 85 at a mere idle was quite intimidating.

Mick Doohan's Honda 500cc 2 stroke or my RM125 with an FMF pipe and shorty muffler.

Ronnie Tichenor. Unadilla 86-87 ?

The trusty pinned round Lierop video, never gets old.

Wards KX500 was the meanest sounding two stroke I’ve ever heard. And I’m a Honda guy.

how about the Honda RC166 250 6-cylinder ?

Formel 1?

I think it may have been the moment but at a Lakewood National in the early 80’s Magoo rode his Honda down to the trackside to watch practice and there was an open field about 80 yards across between where he was and his pit. When he finished watching whatever practice it was he did a wheelie the length of that open field in a single gear , maybe 3rd, who knows, roost coming off and braaaaaaaaAAAaaaaap all the way. It was quiet except for his bike so it really ripped and I’ve not heard anything like it since.

The answer to the OP question is a works Honda 500.

All timer.

Trevor Stewart's yz250 has a different sound to it. I was always curious what was done to it. Sounds very good

The factory 2 stroke sounded good.

But nothing beats the rong pong pong pong idle and buzzsaw sound of the CR 500. I dont think even the KX500 sounded as good.

I've had both 500s. The Honda sounded and held up better, but I still have a KX and a complete spare engine for a reason.

A well tuned 500 2T ridden by a Pro will tickle my nuts....

...prepare for the future..they gonna sound like a pimped out sewing machine.

You can't have a conversation about best sounding bikes without this. I was fortunate to be able to hear it first hand at a Motion Pro open house years ago before the S.F. supercross.

I was fortunate enough to hear one of these ridden in anger. Team Obsolete brought their bike to Laguna one year and did some Laps on it. 16000 RPM. Not a dirt bike but what a sound. Far as dirt bikes go I was also able to hear Kenny Roberts TZ 700 dirt tracker at Delmar years ago Jay Springsteen riding. Woohoo.

Blast from the past right there

Personally my 06 Cr250 granted it wasn't the fastest cr but it made a sound like it breathed and that's what's cool to me.

One day I got passed by a kx 250f with a two brothers exhaust. It was my first weekend on a track. It scared the shit out of me ; yet I wanted that sound.

Dungeys KTM 300 2T last RBSR sounded tits....

It certainly would be somewhat wondrous!

In use, as an MXer, it would have to go down at least a tiny bit low in its rev range, as against the pre singles only 125 GP Road Race class. So, the aural range might have been quite the thing.

Probably the best sound track I've found is from my '97 World 500 MX Championships DVD.

It had the KX and CR500s used by many (some CRs sleeved down to the 400 /430 region) , the booming Husaberg and Husky 4ts of Smets and Martens, the smaller 360/380 KTMs of Nichol, King and Parker, and, the amazing, 'Billet Everything", YZM400s. Now those, the YZM400 Works bikes, had an incredible sound, not remotely matched by the modern 450 4ts to come, or of today.

I do have a love of Bengt Abergs Halman/Enqvist TT, and CCMs. The 3 valve engine Aberg used a bit had a neat, different sound to it, over the std 2 valver. There's a few GP videos on You Tube that give you brief aural symphonies of both of them, generally with Bob Wright on the CCM.

The noise of the Hercules / Sachs Rotary powered Dirt Bikes is quite unique.

The incredible variety of Road Race engine types through the late 50s, to the end of the 60s, when rules were tightened up, made for some amazing sounds and engineering.

Holy shit, Tamir is back!

Yes, very good thread... Much ty!
