• There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

Alternative to a pull behind

just read this if i am reading this correct tongue weight does not apply to this project


Eve*r*yone should know his or her tongue weight. Don't laugh to*o hard about the way that sou*nds* -- tongue weight is a towing* term, not something t*o do with the human mouth or dentistry. Tongue weight (TW) is just one of the many towing terms you'll need to familiarize yourself with if you ever intend to tow a trailer behind your vehicle. It's the downward force that the tongue of the* trailer applies to the hitch of the tow vehicle. Most experts agree that an acceptable tongue weight for any trailer is somewhere between 9 and 15 percent of the gross trailer weight (GTW). There's good reasoning behind these numbers, too. It all comes down to trailer towing safety.

If the tongue of the trailer does not exert enough downward force on the tow vehicle's hitch ball -- meaning that the trailer's tongue weight is too light -- a dangerous condition called trailer sway could result. If the tongue weight is too heavy, the steering of the tow vehicle will be affected. This makes it sound like tongue weight is a big deal, and it is. But fortunately, tongue weight is also easy to adjust.

Just remember that the trailer acts like a lever, and the axle of the trailer is the fulcrum -- or pivot point -- for the lever. If the tongue is too light, you need to move some of the cargo forward of trailer's axle. If the tongue is too heavy, you need to adjust the load so that more of the weight is behind the trailer's axle. It's just like trying to balance the weight of two kids on a seesaw at the playground. That's easy enough to understand, but other than simply lifting the tongue of the trailer and guessing its weight, how could you ever know how much the trailer's tongue truly weighs? And an even better question may be this: How would you determine if the tongue weight falls within the 9- to 15-percent range of the gross trailer weight? Read the next page to find out how you can do just that.

Teddy figured he'd muddy the water with one more alternative for y'all

IMG_20120405_150337.jpgThis uni-trailer was hand-built by a fellow SpyderLover, who sadly sold his Spyder
IMG_20120405_150328.jpgand Teddy was lucky enough to aquire his uni-trailer
IMG_20120405_145845.jpgWe have yet to hook it up and try it out, but are really looking forward to it

Just thought I'd post another possible option to a full-on trailer for those that are skillfull in such endeavors :thumbup:
 
So I see the factory hitch weigh is 17 LBS i think i can keep mine down to 10 LBS this will work great then the box is 17LBS that leaves about 23 lbs of stuff I did look into the GW he has posted on is site and the TW on it. Is 25LBS recommended and yet he is running a large box on it this is worth a try it's cheap money and some time as always I thank you for your input NT wil keep posting here hope to have time Tuesday or Wednesday will post when done
The weight of the hitch has very little to do with it! nojoke It is more a matter of leverage. The tongue capacity is based on the hitch geometry, hitch materials, hitch bushings, hitch fasteners, and the Spyder suspension geometry and components. Add too much weight to the ball area of the hitch and you risk damaging the hitch, hitch bushings, swingarm, wheel bearings, or swingarm bushings.

Not sure what the magic number is, but ...............

I do know, as Scotty has plainly stated, you don't want to exceed the recommended 40 pound tongue weight-limit of the Spyder Hitch.


I know on our Moto-Mate camper, when I first got it, distributing the weight of cargo wasn't like usual. I tried the 40/60 method but got a lot of fish-tailing. I tried the 60/40 method & that caused the rear of the Spyder to turn into a BobbleHead. Found for the Moto-Mate, its 50/50 down the middle, and then its SMOOTH SAILING.


The reason I mention this, is to demonstrate, too much weight on the hitch ball, and you can change the handling characteristics of the Spyder & not favorably. Try taking a corner with your rear end bobbing up and down, NOT a fun experience. Not to mention, since the hitch is "UnSprung" (NO SUSPENSION) can you imagine how bounced up and down anything stored in such a container is going to be? Hence the reason, when Michael built the Uni-trailer we now have, he added its own shock to help absorb much of that energy.

Again, not saying this is a BAD idea, just proceed with caution, please. I'd hate to see someone damage their beloved Spyder or worse & possibly cause an accident or get someone else or themselves hurt, thats all I'm saying. Good Luck!
 
from every thing i have read TW is because the the axle on the trailer to much and your front tires will come up to less and it could lift your rear tire so i don't think TW is a factor here what is a factor is the rear hub bearing how much weight it can take Scotty knowledge of the spyder is better then mine for he has been around them longer then i and he is a very intelligent person from what i can see in is post i am not saying he is wrong nor i am saying he is correct i have fabricated a lot of things in my life i am a A.S.E master technician can some one tell me how much weight the spyder can hold as passengers ???
i am 190 wife is 110 i have seen much lager people on the spyders

my last toy i built

The factory hitch is thin. I'd say 0.060" off the top of my head. I'd have to hunt up my spare and measure to be sure.

Let me get this straight; you have a SPARE hitch??:shocked: :bowdown:
:bowdown::bowdown::bowdown::bowdown: :thumbup:
I always figured that having just one was more than enough trouble for me!

Yeah, but you've got to remember, Bob, that Scotty isn't just any ordinary person like you and me. It takes a lot more to get him in trouble!

Long story, it isn't complete. I bought it for a project, but never got to it. I did get to see the guts of the beast, though, so it was educational. I'm not a weird as Dan makes me out to be. :roflblack:
 
Ok so picked up a scale and started to weigh stuff just to see where i stand on the 40LBS TW
the hitch will be made of steel and Aluminum to keep weight down

IMG_0709.jpg



IMG_0708.jpg


box weight is 15LBS not 17.3 as they stated and that does include both master locks


IMG_0711.jpg


we had some vacuum space bags that we where going to use for our trip to Chicago in July i use a inflatable matters pump to remove air from bags works just as well as a vacuum and fits in the palm of your hand
the pic you see there 18LBS whats included
2 fleece sleeping bag
2 towels
2 pillows

my stuff
2 pairs of pants
3 t shirts
3 pairs of shocks
2 pairs of underwear
1 pair of shoes
wife's stuff

3 pairs of pants
4 shirts
3 bars
3 underwear
1 pair of shoes

that brings grand total to 33 pounds and we still have frunk and both saddle bags to fill
with out this rear trunk i loaded the spyder with every thing you see in pics and frunk and 1 1/2 saddle bags where full that gave us 1/2 saddle bag to work with not much

Question: Sprung vs unsprung weight... Does this affect this issue? :dontknow:
The Spyder carries the hitch and tongue weight as unsprung weight, unlike most conventional motor vehicle/trailer combinations.

how can they say it's UW when every time the trailer on the ball moves up and down that has to be some kind of force there even if it's 5LBS

i believe SW is more of a factor to the rear hub you see a trailers will move up and down on the ball where this will be a steady force of UW that will never change don't get me wrong i would never overload this thing and only sleeping bags,shoe,clothes,pillows because everything in there will be subject movement i may be wrong but this is a test subject i am feeling good about this also this will only be on long trips other then that it will stay on the self

check this out this was a 02 Suzuki volusia 800cc they all said the bike was to small no one at the time made a hitch for so i made one myself on that bike was one great warrior it pulled 32cubit foot trailer to 49 states 6986 miles in total riding 2up


i truly believe this is way within the spyders capability
