KDX owners please read!

well, kdx 200, kdx 220 or kdx 220R owners, Before i can FINALLY convince my parents to get me a dirt bike (of my own) i have to know how loud it is, can anyone with any of these bikes tell me how loud they are? thanx

As off-road 2 strokes go, a KDX in stock form is VERY quiet.
Not sure how to explain how loud they are any other way... other than ride it in your back yard and not get shot by neighbors.

LMFAO thanks

Stupid leaf-blowers are louder than a KDX! Like Okie said, a stock KDX is one of the quietest bikes around.

Just remember to lug it around the house and rip when you are out of earshot.

 

[Psyco Goldfish]

cool, i'll have a shot at convincing mum tomorrow. Not too optimistic though...

 

[kdx220freak]

they are pretty quiet, even if you get an aftermarket pipe, as long as its packed right it can be very quiet

Super quiet bike stock. People laugh at it because the thing makes so little sound.

April 2005 Dirt Bike Magazine
"How Loud Are They?"

Random government test numbers
KDX200.............Stock.............85.0 dB
KDX220.............Stock.............84.5 dB

1/2 dB can easily be a difference in test equipment. Here's some more for comparison

XR100...............Stock..............86.0 dB
KLX110.............Stock..............86.0 dB
PW80...............Stock..............86.0 dB
TTR125.............Stock..............86.1 dB
TTR250.............Stock..............84.0 dB

CR125..............Stock..............94.0 dB
CRF450..........White Bros R4...101.0 dB :eek:
KX250...............Stock..............96.5 dB
KTM200EXC......Stock..............89.0 dB
YZ450F.............Stock..............97.1 dB

Remember 3dB is twice the acoustical energy, so the 89dB KTM 200 is twice as loud as the 86dB KDX. You aren't going to find a quieter bike. The dual layer pipe has a whole lot to do with it. When riding my bike it seems like most the sound comes off the expansion chamber of my FMF. It's still quieter than most bikes out there, even with a pipe and silencer.

THERE is a better way to explain it :)
Thanks adam728.

so your saying my cousins TT125 is louder than my kdx??? ha not!!!!!!

 

[adam728]

A stock KDX is an extremly quiet bike. At the shop I used to work at we had a TTR125, I would have to say that the 4 stroke thump was a bit louder than my KDX was when all stock. Doesn't you bike have a pipe and silencer anyway?

Having had one of both, no way the stock TTR is louder than a stock KDX, sorry.

The kdx is quiet, I had 2, 200 and 220 and with stock pipe it is quite enough that you could hardly hear the person riding up to you on the trail unless they where in fairly short distance, that pipe stock does
block a lot of the power. FMF has nice pipes for this bike. Night and day difference when replacing one for the other. If noise is there main concern the kdx is the best choice if this is mum's biggest concern.
Then later you can get the fmf pipe on it and let them get used to it...lol. Just tell them that the kdx will not be a bad decision and will not be loud like the classic mx dirtbike, it is a trailbike, tell mum that.
Good Luck, I know this is probably killing you in some way. It would be me if I had to have mum decide.

its killing me, oh yes its killing me slooowly and painfully
