Not sure this is the right location for the post. (This is my first post)

I did a test drive on the 08 1125R last weekend and I have to say that I loved it. There was only one thing that kept me from pulling the trigger: I noticed that the gas tank was getting a little warm towards the end of my 30 minute ride. (At the end of the ride I was not riding on the freeway anymore, I was riding on the back roads.) I asked the sales guy if that was normal but I felt that the HD guy was just saying what I wanted to hear. Can’t blame the guy, he was trying to make a sale…

I keep hearing the 09 models have improvements. I have spent quite some time researching the improvements and I have not found much yet in regards to the improvements on this particular matter. I am tired of looking so I will ask you, the users, has any of you experienced any temperature on the gas tank? If so, can you please specify your model?

I appreciate any help. Thanks in advance

it is COMPLETELY normal, the frame is also the gas tank, and when a HOT engine is in the frame, the gas and ALUMINUM frame transfer heat out.

I have an 08' 1125r and ever since the last flash the heat has been NOWHERE near as hot as it used to be.

the 09's do have a type of insulation between the engine and frame, but heat is still transfered through it, and others on here have had the very same insulation put on their 08's with very little improvement.

so all-in-all its just the nature of the BEAST, dont let something small like that deter you from getting a truly AMAZING machine.

lamen's terms: THIS THING IS LIKE PUTTING A ROCKET BETWEEN YOUR LEGS, SURE ITS GONNA GET HOT, BUT YOUR GONNA HAVE THE RIDE OF YOUR LIFE

If you put Tech Spec grip pads on the bike, you notice the heat a LOT less.

My track bike has them, and I'd all but forgotten about the hot frame/tank issue.

When I bought my second 1125r a few weeks ago for the street, it doesn't have them, and wow, that thing is HOT!

Just part of the bike's character.

Some owners have insulated the inside of the frame with a layer of reflective/insulative something-or-other.. basically, something to help reflect the motor's heat away from the frame. It apparently helps.

For me, I just wear leathers, not jeans, when I ride, and I don't notice.

+1 on the tech spec grip skins. I've noticed huge difference of the heat transfer to the inside of my legs with the grip skins on. The wife drove the bike through an almost 300 mile ride through the rockies on Sunday and stated that the grip skins definitely kept the inside of her legs cooler than last summer. The only issue is (and I still need to contact the company about this) but the grip skins do not want to stick and keep sliding down ... even while just sitting in the garage.

Thanks for the info Geforce. I don't see any paint coming off like you had. One thing that concerns me a bit is that you said the new ones are not releasable? So they become a permanent fixture to the bike?

My 09 1125R had its first day out in the real summer which has just started in the UK, the frame got a bit warm after one hours riding when running slowly in urban traffic at less than 30 mph but is far better than the original demo bike I rode when the 1125R first came out.

Welcome, Redhead!

Mine also runs a little hot --- but nowhere near as much as when I first got it home. Everyone said, "It's normal, it's normal," but then I noticed the coolant was .5 qt. low. Much better now.

Still, at my next service, I am considering a heat shield, as recommended by several users here. Buell makes one, though I understand there is a better one available somewhere else. Can someone refresh my memory on this?

Regardless, even without a heatshield, this bike is incredible.

American Sport Bike sells rolls of Thermotec for around $60.
A roll is supposed to cover the whole of the inside of the frame where as the kit from Buell (I've heard) covers far less.

The adhesive will not retack once it is applied. It's only permanent meaning, if you remove it, it won't retack. Not, if you remove it, you'll have to get out the tweezers and then repaint it kinda stuff. Mine stick great and I have no need to take them off. Very happy with Tech Spec for sending me a fixxer upper set.

Thanks guys. I will probably go back to the dealer this weekend and do another test drive. (That should re-assure my decision on the 1125R.) Now the hardest decision will be to pick the color. It looks like I will be breaking the piggy bank for the down payment really soon. I will do my best to post pictures. .

White is not only slower, it suggests you bought the bike so it would match your pink leathers and baby blue boots.

Black is the fastest color.

Then why are the motor, belt, pulley, and tires black?

Because they have to be! White would be to slow to use on the fast parts.

The grips are black, too. That's because really fast riders can't ride a bike with white grips. It slows them down too much.

read the conclusion....
COLOR ME FAST - Derby Tech - May, 1984
by Tony Carlini, Sr.



PREFACE

Before beginning my article, I would like to take this opportunity to than all the concerned people who wrote to Tony and myself with their supportive thoughts and comments. Tony, however chooses not to participate in derby events indefinitely. He is now quite active in Go Kart racing. I am extremely proud of my son by the way he conducted himself with the officials, inspectors spectators, and competitors, even while attending night court. His driving was not affected by anything, and every run down th hill whether it be straight, fade, or swerve, was predetermined, an executed perfectly. Driving is a very important ingredient in becoming national champion.

For those of you who don't know "Tee Jay" (Tony's nickname), he is the boy from California, who won the 1983 Junior Division World Championships in both the All American Soap Box Derby and the NDR, Gravity Drags. It is th first time that both of these titles were won in the same year. Others have won both of these titles in the Senior Division, but not in the same year.

Editors Note: A soap box derby racer will run comparatively faster if it is color coordinated properly. Over 76% of all responses to last month' questionnaire thought that color makes a speed difference. It does, Pau Gale's response touched on the physical and Psychological aspects tha color has on speed. These two areas are important and deserve to be expanded upon - - - - - -ED.

PHYSICAL CHARACTERISTICS OF COLOR

The color that provides the least skin friction drag is black. Black also helps prevent separation of the laminar boundary layer.

The aerodynamic book "Theory of Wing Sections", page 109, written by Ira H. Abbott and Albert E. Von Doenhoff, explains that skin friction for an object (soap box racer) that absorbs no heat from the free stream is, lets say 1.330. The skin friction for a soap box that is 1/4 the absolute temperature of the free stream is 1.420 at 50 miles per hour. This means that the laminar skin friction increases with heat transfer from the fluid (surrounding air) to the surface of the racer. This increase is small even for the extremely low racer temperatures. This means that the surface temperature of the racer should be as hot as possible. The color of the racer should be one that absorbs as much heat as possible from the sun. This color is black!

Another aerodynamics book, "Boundary Layer Theory', written by Dr. Hermann Schlichting, page 467, explains how heat transfer to and from the surface wall (surface of racer) affects the transition of the laminar boundary layer to a turbulent boundary layer, causing more aerodynamic drag. heat transfer from the surface to the fluid (air) at VERY HIGH SPEEDS (Mach 2 and above) has a destabilizing effect on laminar boundary layer flow, but at low speeds the reverse is true. Therefore' a racer going 30 miles per hour with a hot surface (compared to the ambient air temperature) will have a more stabilizing effect on the boundary layer, thereby causing less air drag, and a faster racer. Again black is the best color.

"In 1949, Fred Derks, of Akron, figured it all out with a complicated system of calculating heat, pressure, and resistance. He raced a black car and won handily". (Popular Science, May 1952).

A word of caution at this point is necessary because color selection aione is not enough to make you win, but it helps.

There are some myths relating to color that I want to dispel. The following theories may sound logical, but they just don't work.

1. The black car transfers heat to the inside of your racer and causes resiliency loss in the epoxies, resins, and fiberglass. - The temperatures required to initiate their softening is in the area of 145* F. and up. These temperatures are never reached inside a racer.

2. The front half of the racer should be white, and the back half black. The white being cooler than the ambient temperature of the air, contracts the air, pulling the racer into this partial vacuum, and the rear being hot, expands the air causing a pressure rise, in the rear of the racer propelling it forward. - This sounds great, but it does not work on hill tests, wind tunnels, or anywhere.

3. A black car heats up the air around it, which causes it to thin, making it easier to penetrate. - Black is not better for this reason.

4. A white racer is better because it will reflect the heat to the wheels and axles causing the racer to run faster. - Wheels and axles do run faster hot, but a white racer does not radiate enough heat to achieve these results.

There are truths to the following that not only sound logical, but they actually work.

1. A black racer and black axle trees, or any color racer with black axle trees will get hot by building up heat from the sun, and radiate this heat to the wheels and axles, thereby increasing the racers speed. I have tested these and I know that the temperature of the wheels and axles are slightly higher, which makes them slightly faster.

2. The inside of your racer should be warm. The heat adds resiliency to all component parts and causes them to use less energy during deflection.

3. A black nose will absorb more light than any other color, giving you an advantage of 3/16 to 3/8 of an inch when racing under the timer swap system, such as Fort Wayne's (ed. NDR nationals site). Other colors reflect light back into the timer eye for an instant longer than will a black nose, thereby increasing the time required to stop the timer. This is the reason you find a black nose on both Tony's winning All American car "Ya Snooze Ya Lose" and his winning NDR car "Flyin Tiger". Although a timer swap was not used at Akron, the car first had to win its local race, which was a timer swap.

4. A white car's nose will show up on Akron's overhead camera better than any other color, which might give you an illusion advantage of 1/4 to 1/2 of an inch.

Now, after I've stated all these facts, you might ask, how much faster physically is a black car over a white one? The answer may surprise you by its smallness - about six inches.

PSYCHOLOGICAL CHARACTERISTICS OF COLORS

The black car has the physical potential to run the fastest against a clock. But when you run against an opponent, psychologically speaking, you should use a car of a different color scheme. The difference that color coordination makes may also surprise you by its largeness. It, by far, out distances the gains of an all black car.

The goal of color coordinating is to create the feeling of power. This puts you in a positive mental attitude, and your opponert takes on the submissive role. Pick a color that is disturbing to your opponents - not one that is pleasing! You can use color to create stress or make drivers fearful; like the American Indians did with war paint.

The idea here is to create unpleasantness and to arouse your opponent in an anxious unsettled way. The best color to accomplish this with is a pale red, followed by yellow, orange, and black. The most disturbing yellows are highly saturated, but not bright. You also need a little bit of a strange design too, some kind of intricate, disturbing pattern. My son's car "Tony's Flyin Tiger" is a good example of causing stress in the driver of the Tiger's opponent, as was shown at the Fort Wayne Championships. The quality of driving by the opponent is greatly diminished. If you'll think back to the NDR finals at Fort Wayne last year, you'll remember that no one had a good drive against Tonyl Against the top three competitors, one drove off the track, another was wobbling back and forth all the way down. The only top competitor that had a fair drive against Tony was Jeanne Barr.

The Cincinnati Bengals also use a similar type color scheme on their helmets, which creates stress in their opponents.

Other color schemes are dominant, which gives your opponent the feeling he is being dominated, which again causes him to drive poorly. The best colors to use to create the feeling in your opponent is black. Black is the color of power and dominance. It also signifies evil and badness. Black is especially effective when used with charcoal gray. These are the reasons Tony used these colors on his first junior raber. many of you will remember him racing this car at the NDR Championships in Allentown, PA. These colors are effective, but at only about half the value of stress causing colors.

The Los Angeles Raiders, one of the most dominating teams around, use this dominant color scheme in their uniforms. In derby racing competition, the most important colors are those that cause stress. They create confusion and the feeling of being dominated.

The largest drawback when using these color schemes, is that they also affect the inspectors, and officials in the same way.

Of course the most pleasing colors are blue and green, but the most unnoticed color is a cream white. This white has a neutral effect on people, neither pleasant nor stressful. Tony and I knew that his All American car was fast, and had a very good chance to win Tony painted his car white in an attempt to avoid the label as the favorite or 'what inspectors and officials refer to as a "ringer", a term they privately use to describe a very competitive car. A "ringer" is put on the "hoochie coochie" list, for extra curricular examination of possible rule infringements. Tony and I both thought that even though white is not the fastest color, it would be the best color to use in the All American, and hopefully allowing him to spend more time enjoying himself at Derby Camp.

I estimate that Tony's color coordinated scheme was worth an average of about 18 inches in driving results alone.

CONCLUSION:

The aerodynamic experts say black is the best racer color for potential speed. It is. However the proper color coordination can net you an average of a foot and one half, simply due to the confidence factor being translated into driving performance.

ADDITIONAL COLOR COMMENTS BY TONY CARLINI

Black is also known for its unique "bleeder" effect. I'll give you an example to help you understand this terminology.

If you were to pinstripe a black car with two 1/8" wide stripes that were 1/8" apart, using red for one and blue for the other, you would find that from 25 feet away you would be reading only one color and that color would be purple. The color achieved if you would have mixed the blue and the red paint together. This effect only takes place on a black background. Try the same test on a white car and you would easily be able to detect a red and a blue stripe. When using only a one color line on a black surface the same blurring effect takes place but not instantaneously. The line will not be sharp after the eye has been focusing on it for a while. This is the reason that most of your schools have done away with "blackboards" they are now "greenboards". This particular shade of green used on such boards is the most pleasing color to the human eye. It can be tolerated for great lengths of time with no stress effects.

Greens however, can be extremely stressful when combined with hot pink. If you have ever taken an eye exam for color blindness you were shown a card with green and pink dots and asked if you could detect a number hidden within the dots. It is very difficult for the human eye to draw a crisp, even line between these two colors when they overlap or butt into each other. A well known California restaurant chain had a wallpaper developed for their restaurants using these two colors (lime green and hot pink). Why? - Because they were faced with a quick turnover problem. People taking up a seat or booth for 45 minutes to an hour, and sometimes ordering just coffee. Long lines and turned away business is the result of such activity. Their problem was greatly reduced after installing the wallpaper. It's subconscious effect on these people made them eat, drink, and leave without ever realizing any abnormalities.

The color hot pink by itself is a severe energy drain. It affects the sub-conscious mind in dramatic ways. A person accustomed to doing 100 continuous pushups can only do 75 or 80 on a pink carpet. If you don't think it is true try it! Bright yellow or as some call it "chrome yellow" also has strange characteristics. This is the color Tony used along with black for the Flyin Tiger paint scheme. I used to own a 1932 Ford Coupe when we lived in Michigan that was painted this color. I could never understand why the roof, hood and trunk (all flat areas) would attact bugs such as mosquitos, flys, etc., whenever I parked this vehicle under a street light at night. There would be 50 or more dead bugs laying on these surfaces whenever I would return to my car. The color combined with the ultra violet light attracted the bugs and then attacted their nervous systems until they could no longer tolerate it thus killing them.

overload


Back on topic - look at the design, of course the frame absorbs engine heat.
On a long Summer ride, the frame gets progressively warmer as the tank empties.

Ooohhh that fresh gas fells so nice and cool as the frame fills back up.

repeat.

+1 one the kewl fuel!!!!

BTW, I feel the same thing on my ST1300 and it has a "conventional" steel gas tank (as well as one b/t the frame under the seat).

Darn that old story of power makes heat and it has to go somewhere before it gets absorbed by the "great heat sink in the sky".

I was reading that post about the colors being faster than one another, and while anecdotal, it was interesting. Right up till it was written that the Cincinnati Bengals stress out opponents and the Los Angeles Raiders are a dominant team!

I found this really funny also:
White is not only slower, it suggests you bought the bike so it would match your pink leathers and baby blue boots.

Just a small input here guys but what Zac has said is right on track about fuel. If possible keep it at least half full especially when in heavy stop and go traffic as in commuting. I also added some black exhaust wrap to my head pipes especially the rear one where it is close to the frame. Double wrap there and even with my full lowers blocking at least some of the air flow on the headers I have much less heat radiating to my legs and the frame. If you do not like the look of the wrap at least put on some behind the exhaust guard on the right side. Bob
