Without having any scientific proof to exhibit, I would have to presume the RG is significantly more aerodynamic.  Why else would it exist???  A bit too Japanesque for most of the HD guys... I've owned a few of both, and the RG "seems" moreso... but that's not very scientific, is it?

[mfgreen]

You know Hubbard, that bring up an interesting point.
Which bike is more aerodynamic. Ultimately aerodynamics do factor in, if everything else is equal except for that. I bet I know someone that can give a good answer.

Mike are you there? Mr. MFG if you know that answer please let me and Hubbard in on the answer.
I have never raced a R/G (does that mean I exhibit virginal qualities?)

Inquiring minds want to know.
That picture floating around the site of the dresser at the dragstrip might be an answer.
Did that guy race a Electra Glide instead of a Road Glide for some aerodynamic reason or because that's what he had? [smiley=nixweiss.gif]

And Hubbard I do have a hard time relating momentum to acceleration. [smiley=confused5.gif]

 

Both fairings are limited in their aerodynamic capabilities.  The Road glide fairing when mounted in its stock position vs. the "batwing" fairing of the Electra Glide family. THe Road Glide fairing will provide more stability and down force. The reason is not due to the shape very much.  Iti is more due to the position and the fact that it is a frame mounted fairing rather than a steering mechanism mounted fairing.  Air densities that vary are buffeting these fairings at given velocities.  Because the leak out of negative air pressure behind each fairing is different and less constant behind the"batwing" the stability is more compromised rendering lift and steering instability due to the "light" feeling created by the upward movement of the center of effort shifted by the low area of the batwing's pressure loss.

See Hubbard! [smiley=laugh.gif]

I knew he would have the answer! [smiley=xyxthumbs.gif]

Hey Guys,

Just my .02 on the Road Glide vs Electra Glide issue.  

My previous bike was a 2000 three tone red SERG. This 95" bike with SE heads, high comp pistons, SE Throttle Body, SE-211 cam and V&H pro-pipe made substantially less HP and TQ than my current SEEG.

However as HUBBARD said with regard to his observations of OTIS the SERG had absolutely no tendency to become unstable at high speed. In fact when I traded the bike in it had 25000 miles on the stock front tire and was still very stable.

The SEEG on the other hand developed a tendency to become unstable at approximately 108MPH. The problem which I first noticed at approx 5000 miles became so bad that I replaced both tires at 6500 miles. This seemed to help slightly but did not eliminate the problem, so I had the neck bearings re-adjusted on the tight side. This seemed to help more so I recently had the bearings "tightened" further at the 10 k service. Since this was performed I have only ridden the bike a few miles but it certainly feels much more like it did when new.

Based on my own observations the SERG, even though it lacked the stronger swingarm introduced in 02, was more stable at high speed than the SEEG is. The only time this may not be true is a high speed turn, where the extra strength of the "new" swingarm gives the SEEG the edge in my book.

I for one would love to see H-D bring the SERG back.With a 103 and the the new swingarm it would be one BAD ride.

At 135 MPH, I will take my Road Glide!

If you care for a little expansion on the technical side of fairings, you can read this article.

Then couple that knowledge with this

At 135 MPH, I will take my Road Glide!

At 135 mph I'll likely take a clean diaper.

                                                OTIS

So at 135 you will be behind Magoo's 138

Oh well,, following taillights is something I've had to do before. But not often!

[HUBBARD]

Hey OTIS,
 I'm sure you will confirm, there is no way we would dirty our diaper at 135. [smiley=shocked2.gif]  That orifice is tightly secured from about 100 on!  Glad to see you participate!  I'll bet Shrader and you and me will have a blast with these guys when we meet up!  Ride easy--HUBBARD

[kng103]

certainly not with those dyno results on a bagger.

what dyno results ? am i missing something? or are we just F'in around?
is hubbard, shrader, and otis the same person?

[hd2003-se2005]

There's a whole new equation that has to follow on to this.

[SHRADER]

Thanks MFG for pointing out the obvious. You only got one slight detail incorrect-I am not the service manager, I am the manager.

In an effort to clear this up I stopped by the Dealership and took a picture of my bike. The quality is terrible but it was the best I could do under the circumstances.

PS

OTIS and I are talking on the phone and we figure that if he,  I and Hubbard were the same person we would be:

Person weight   HUBBARD 240 + OTIS 230 + ME 245 = 715lb

Bike Weight    Maudie2  1070 + OTIS 843 + ME 830= 2743lb

HP      130 + 95 + 107 = 332

This all equals one big f---er riding one h--latious H-D with some serious  diaper dropping HP

Como su papa now? [smiley=beerchug.gif]

[hd2003-se2005]

Shrader

You guy's crack me up! [smiley=laugh.gif]

[hd2003-se2005]

And good looking bike also.

It would have shown up better in the picture if it was red! [smiley=nixweiss.gif]
