Have any of you installed a lower, smoother, more aerodynamic body on your Harbor Freight, Aluma or PiggyBacker frame? Pictures? Suggestions? Just thinking of an improvement project.
.. egg shaped....Suggestions? .
I'm perplexed by your comment. Do you have a trailer you'd like to brag about, or are you just a roadsign shooter?
I'm thinking about building one of those for hauling extra stuff around on short trips or trips where my camper isn't needed , just thinking about a flatbed version to carry icechest and bow case . :lol:I'm not sure how much aerodynamic difference one would see with one of these flatter cargo boxes by turning it around. If any it would be very small in my opinion. I just finished mine last week and took it for its maiden voyage Saturday. I'm very happy with the outcome..

That's a nice looking trailer you got there.I'm not sure how much aerodynamic difference one would see with one of these flatter cargo boxes by turning it around.

You may be right, Jerry, but my initial impression on my first ride with the PiggyBacker was a feeling of wind drag. I dropped my wife off, hooked up the trailer and took a spin. It didn't feel like weight, it felt like wind resistance. I actually think a tall thin trailer might connect the wind coming off the back of the Wing even better than a sleek, low trailer. Sadly, nobody makes a box shaped like that.I wouldn't worry too much about the aerodynamics and focus on the looks. Trailers draft in the wake of the bike and probably don't create much additional drag.
Its called a SportRack Aero XL.. Dimensions are 63"L x 38"W x 19"H.. I purchased it at Dicks Sporting Goods for $279. It opens from the rear and seems as well built as the other main brands I compared it to.That's a nice looking trailer you got there.
What kind of cargo box did you use?
Howdy, Jerry! As of last fill up this morning I have 936,863 miles of puling trailers with motorcycles and 1,138,869 miles of riding all together. There are interesting interactions involved when pulling a trailer. You may know that in high speed races in cars or even bicycle races that the leader of a twosome also can go faster with his chaser close behind. That effect is true while pulling a trailer also. Therefore using a strain gage on the drawbar of a trailer does not tell the correct story.Thanks Tom, that's interesting. Have you done any wind tunnel testing with a trailer behind a motorcycle? It would be interesting to see that done using a Goldwing with 2 people aboard as that's how most of us travel instead of a trailer standing alone in the wind. Better yet, take that test to the road using some kind of scale in the tongue to measure the total amount of energy it takes to pull a trailer. Then compare a streamlined trailer with a boxy one. Then add a big cooler to the tongue, right in front of the cargo box like I have done. I'm guessing that big cooler really wrecks the airflow.
For what it's worth... I ride a 1500 wing 6,000 miles a year and tow a trailer about 25% of that. In my wildest dreams I could never rack up the kind of miles you talk about! So while all of this may be important to you and many others out there, it doesn't really matter to me. If I pull an inefficient trailer and lose a couple of miles per gallon vs a more efficient one it's only going to waste $10 in fuel per season. I can afford that. You always say your trailers aren't for everyone and I appreciate that. Thankfully, we have a lot of good choices.
