I think the MGX is stealth.

[Luap McKeever]

Assuming the MGX is similar to my 1400 Eldo, it is actually fairly accurate. About 3 mph off in the indicated 70 mph range. The odo is very close to my GPS, within about 3/10ths per tank. The other Cali's I had were 11.66% optimistic. (White face Veglia.) 80 was really about 72/73 mph.

The MGX is very accurate.  GPS indicated 80 will read 78 on the speedo.

On my Convert I always "sneak up" on those radar signs that show your speed.  If one does see me, it's as I'm going past it.  Usually they remain dark.  It annoys me, since they are a convenient means of checking your speedoneedle.  I attribute that to the size XL windjammer.  It sheds more than wind.  And NOBODY is going to change that belief!   

I regularly peg the throttle when I see one of those signs, I might even do a little weave to try and make my profile bigger.

But on pretty much all the bikes it doesn't register my speed until I'm almost past it.

Doesn't matter if I'm all along on the road (and the sign is off/reading nothing) or there's other traffic around and it's reading their speed (which is obviously different because I've pegged the throttle and I'm either closing or pulling away rapidly).

In a only tangentially related note. Having recently added the Police King to the fleet I didn't have extra velcro tabs for my EZ pass so I either kept it in my jacket breast pocket or even tried strapping it to my arm. But I noticed some of the EZ pass booths flashing "Toll Unpaid" or the like on a trip. So when I got home I checked the account and was surprised to basically see non of the tolls charged. I expected license plate violation tolls to appear in the upcoming month but it never happened. Then I realized that I placed a very large HB topcase over the OEM luggage rack/radio mount and that most of the tolls were EZ Pass Express so the cameras were all mounted up high. Must not have been able to see the plate at that angle.

Law enforcement use a number of systems to measure speed from rather archaic constant wave to Lidar (doppler laser based system). It will also come down to what the instrument its "tuned" to accept as a valid reading and reject elevation changes if the road it straight or curved although most law enforcement organisations have rules about using measuring systems on bends, if their people actually follow them thats another issue.

So it is possible a motorcycle may not reflect enough energy to be measured although I doubt the presence of carbon fibre would have much to do with it. The best reflectors of RF/Radar energy will be solid and have close to 90 degree orientation to the direction of travel. Stealth aircraft in the main simply deflect energy away from the receiver some absorption occurs but especially on something that is supposed to fly its not very practical. With aircraft like the F-22 and the F-35 (do we get to call this one the pig too because it might fly?) with newer radar systems etc simply been stealth is not enough, anyway I digress.

On a Guzzi the best reflector is the engine and probably the fuel tank if its metal so the other possibility is if your detection system (cough parking system that happens to coincidently mess with speed detection) is up in the fairing its likely it starts doing it job before the main reflector is able to give a good enough return for a reading. Or maybe you get lucky the guy/girl has met their quota for the day and CBF'ed.

The cop was probably texting his girlfriend...

I have found that just about every state will give you 6mph over the limit (except Ohio). Therefore, I ride at 5 over...

Here's a video for anyone deluding themselves into thinking their smaller profile or "aero" fairing is really fooling the speed gun. Starts at 5:00 for the relevant bits.

Its been a good two years or more since I have had rollers in anger behind me.  So I just keep going, make your choices as wisely as you can, and roll on that throttle.  A human being can have a whole lot of fun traveling from 0 to 90mph, and places in between!  And I find the fun in amplified when doing it on a Guzzi!

This is mostly my Kansas experience. Most of the time that I might be in the ticket zone is on rural, very low traffic, extended visibility roads. When I have happened to have a meeting of a LEO along route I have been ignored, light flashed, palm downed signal, etc. but not stopped and I am usually 15-20+ over. I am thinking they guess I am still riding safe for conditions and my only threat is to myself.

  I always liked the opening scene of "Second hand Lion".  The dozing Leo with radar when the two old geezers in an ancient biplane flew under the overpass where he was and tripped the radar at over 100 MPH then gained altitude and escaped before he came fully awake.

There is a street that T-Bones into mine right where my house is and it has stop signs on all three corners. Since there is a major intersection that backs up during rush hour a lot of people have discovered my street as a cut through to avoid delay at the intersection. The speed limit is 25 but all these folks are in a hurry and drive 35-40+ and pretty much never come to a full stop at the signs. I look out my living room window with amazement at how many just blow through the stop signs without so much as a touch of the brakes.

So every once in a while the city will send a motorcycle cop to hide across the street to ticket those who do not stop. Much to my dismay it is rare that they ever stop a car and issue a ticket. It has to be a really flagrant violation to get them to go after someone. My guess...

Cops get lazy just like everybody else!

That video doesn't show or prove anything.

With all due,

The funny thing about that video is its not relevant.
This is a discussion about "normal" riders detectability while riding the byways and down the slab and meeting a police radar unit either on the move or in a stationary position, not focused efforts to bust ricky racers.
Completely different situation.
