VTX Trailer hitch

Alright, so the first time I loaded my saddlebags up and went on a weekend ride with the wife I decided that I needed a trailer. First, however I'll need a trailer hitch. I have to apologize for this post being so long. You can go to http://picasaweb.google.com/arch01com/VTXMotorcycleTrailerHitch?feat=directlink to see ALL of the pictures.


I bought a hitch from www.hitchusa.com last year and IMHO the materials are good and strong, however the design is crap. So onto installation

This is just the initial picture of the fender removed. If I were you I'd always remove both shocks and chrome fender struts before trying to remove the fender. Harder to scratch it then.

This is the hitch 183 from www.hitchusa.com


They wanted me to drill out the threads of the sub-frame and use these stove bolts to bolt the whole thing together.
:yikes:!!!!HAHAHHAHAHAHAHHAHHH!!!!:yikes:
That is CRAZY talk.


This is a quick fitment check to see where the hitch sits.


As you can see, the hitch sits inside the sub-frame, however it does not sit parallel to the sub-frame so some heat and hammering would be needed to persuade it to become parallel


As you can see, the hitch does get to the 8" mark at some point. The sub-frame has an interior dimension of 8" so now to persuade the hitch to see it my way


A little wood block and the right amount of heat should do the trick


I have not rented a set of oxy-acetylene tanks as of yet so I had to use MAPP gas to heat the metal. It will do it, but it takes a lot longer than one would expect.


So now it fits better, but not great.


I decided that four line-up pins attached to the sub frame would allow me to easily remove the hitch and keep me from having to drill out the threads. I planned on welding another nut to the sub fame so as to actually attache the hitch.


Ok, the stock Dunie is 6.5" wide and at this point I am planning on using a 165 wide tire. I had pretty much come to accept that I was not going to be able to go wide-side


Welding the attachment pins in place


The outer side of the pin will be cut off and ground down later.


After all welding and grinding is done.


This nut, welded to subframe by Honda, was not meant to be pulled inwards towards the tire an the weld failed. Good think I know how to weld.


Hitch assembly in the fender. Did I mention that I do not like the design of this hitch.


So, the rear fender support and the 183 hitch like to take up the same space. BAD DESIGN!!


Dammit


My goal here was to install this hitch and a CT. Up until this point I was expecting to get a 165 up between the rails. As that many other modifications were going to be needed, I decided to just scrap the whole design as it was and go for broke. I marked the 183 hitch, cut off the excess and tack welded it up so that the outside of the hitch was flush with the outside of the sub-frame.


Looks good to me.


Still looks good. I'll cut those pins short later.


I like this idea much better.


As you can see the hitch is now lined up with the inside surface of the sub-frame. When I test fitted the assembly into the fender, the hitch section was coming in contact with the inner fender supports. I re-tacked it to the inside and all fit was well so I followed that up with a couple of 1“ continuous welds. That'll hold up a light trailer easily.


So, the lower section and the inner fender support liked to take up the same space so I decided to remove the damned thing and turn this into a hidden hitch. Had to add a couple of angles to attache the square tube to.


Once the angles were welded I realized that one of the legs on the top angle was going to come into contact with the CT and had to shave it off. I had to build a little spacer to get the tube in the right place, then I welded on a chain with a hitch pin so that it is always there to attach the lower end of the hitch.


Tire is fully up into fender, approximately at the top of its travel. not sure if I've ever bottomed it out, but just in case.


View from bottom of receiver.


I'll have to cut off some of that.


Hitch in the fender. It fits like a glove.


Look, the fender support fits when I redesign the hitch.


A little mineral spirits to clean it up, two coats of automotive primer and two coats of epoxy paint did the job.


The finished product. !!!APPLAUSE!!!


Attached to the bike for final clearances checks.


Tire at the bottom of its travel


Tire at bottom of travel (approx)


Tire at top of travel (approx)


5/8“ clearance on left side of Dunnie


3/4“ clearance on right side


1/2“ clearance at top cross member.


Hitch installed in the fender for the last time.


So now the hitch is installed and time to move onto the trailer fabrication. I'll let you guys know how that goes once it is done.

Good Job, I too used the same hitch. I didn't go to that much trouble though.
I found some SS carriage bolts somewhere and drilled a hole in hitch to line up with last fender bolt and used a 5/16 carriage bolt. 3/8 in front hole.
have pulled trailer for 10k miles plus. Shoulda done it earlier in life. easier than scrimping and not taking. Longest trip 20 states and 11k miles in 5 weeks camping all but 2 nights.

Well I for one appreciate the effort you went to both the fabricating and the post. Im going to either have to do away with my foots mod,or get a outside hitch or better yet 1 more bike for traveling :mrgreen: Good job and keep us updated,this should be in the how to section.:thumbup:

You want to use a 1 1/4" square (outside) for your insert as this is the industry standard and there are aftermarket options available. For the receiver, I used 1 1/2" square tubing with a 1/16" wall. This allowed a 1/16" clearance each side. You can get a 5/64" wall, and in theory it will fit the 1 1/4" TS, however I would expect that it would be too tight. A tip would be to not exactly copy the 1 1/2" TS attachment from my photos because I learned a few things after I got this done and mounted. You can probably get most of this stuff at Lowe's, however if there is a metal supermarket in your area check them out, you can typically get some "scrap" pretty cheap and only buy what you need.

http://www.metalsupermarkets.com/

1st, Mount the 1 1/2" TS as vertical as possible, this takes out the need to measure angles other than 90 when making other attachments.

2nd, Put the hole for the crosspin (in the 1 1/2" receiver TS) on the lower end so you can reach it once it is all up under the fender. I have since modified mine so the hole is lower and I can get to it easier.

3rd, When mounting the 1 1/2" TS I used a bit of angle at the top which would have provided plenty of support had I not had to cut away one of the legs of the angle because of tire clearance.

4th, Test the hitch once it is complet by standing on it, or at least loading it up with a couple hundred pounds. While you will never have 200 pounds directly on the hitch, it will experience momentarily increased weight when you hit bumps in the road.

The trimmed angle failed and I had to have the wife come and get the trailer. Once I modified the design with a lower, vertically mounted receiver portion and replaced the flatbar section with something beafier the hitch has pulled my test-rig about 70 miles or so with no problems.

Good luck and post some photos when you get it done.

hitch

The hitch you bought is similar to the one I made for my 04 1300c. The top arms bolt to the frame with grade 8 bolts. The lower end is squared off and a receiver type setup is used. With the hitch off and powder coated to match the bike, most people cannot tell there is a reciever on the bike. I've used this setup to pull my Bushtek about 20k and welded another hitch to fit the QuickCamp. Pulled the QuickCamp to a campout last weekend and it works great. If I knew how to work the camera on my phone, I post some pictures.

Good luck with your hitch and welcome to the trailer trash.

Thanks for the info and the tips. I will start shopping in the Orlando area for the materials. As soon as I get it done I will post the pictures. I should be done in the next couple of weeks.8)

I used that link as well. Just got back from a trip throught Alberta, BC and Washington. 3744 km (2246 miles) pulling a one wheel trailer. Hitch weight was 80 lbs. I had no problems with the hitch at all.

The one I built back a few years ago is real close to that one, but I made my fender braces part of my hitch. Seeing as the hitch is now a part of the subframe it made more sence to do that. Nice job.:congrats:

1/4" is what I used also. Haven't had any sway/wobble problems at all.

So which of you guys that are successfully making your own are willing to make another?

I moved off a 'Wing to my VTX, and really need a trailer hitch for my flag pole rig for PGR missions (I had a three pole flag holder that slid into the receive on my 'Wing). Never pulled a trailer, but I want something strong enough that I can if I choose. Also want something with enough clearance for a CT.

This is what my hitch looks like....sorry I forgot to post the pictures before. I compiled ideas from other members, that is why it looks so much like the pictures from other hitches on the forum. The one thing I added, as you can see in pic #5, is this locking bolt that helps eliminate the rattle between the hitch and the receiver especially when I use the flag attachment.
