Another WR250R Rear Rack (Designed with options)

Another WR250R Rear Rack (Designed with options)
(I’ve had this for a while .. sorry for just getting around to posting)
I had been wanting a wide rack to better support the tailbag so I sketched it up in CAD and sent it to Tom at AMS http://www.automotivemachine.com/moto.htm -- he did the analysis and cleaned it up a bit
Below is the result .... a very strong rack with plenty of options

Fits and supports my Tailbag perfectly …

Comes with pre-drilled holes for mounting a RotoPax across or front-to-back.

The RotoPax should be flipped over so the spout is on the left side of the bike.

Also comes pre-drilled for the Givi MonoKey lugs for mounting a Givi MonoKey Topcase.

Plenty of solid Aluminum in the center just in case you come up with something else to solidly mount -- all while still providing plenty of slotted areas for straps and the such.

Tom has since adjusted the length of the spacers so the rack is now just a tad bit lower and fits parallel to the rear tail plastic.

Nice... Great example of form following function as well as overall bike use versatility/adaptation.

That's slick. Smart, too.

Looks pretty skookum Larry! Any idea on pricing?

Nice rack, is it only going to be available for the WR or are there going to be made as a "universal" thing for most bikes?

Hey SheWolf and Tibarus ...

Price -- not cheap - but I like the options, even thou I sketched it up in CAD Tom had to do tons of clean-up in his tooling program as the file didn't translate well ... but now that he has the file additional ones would be easy to make (and cheaper then I paid)- If anyone would like one contact Tom as AMS.

Universal -- depends on what you are putting it on -- Talk to Tom - I bet he could make it work.

Thanks for the post. I just ordered a big rack from Automotive Machine and Supply. It should work nicely for my upcoming long ride through the mountains. At the moment I just have a cortech sport tail bag on the back, but this rack should allow me to add a gas tank and larger bags.

I have one of these on my wrr, it made it thru the eastern part of TAT with a helmut bag full of things like a one gal of gas, tools, tubes,extra clothing, tire patch stuff etc., really quite heavy (maybe 20 lbs.). I had shorten the spacers about a quarter inch that came with the rack ( believe Tom is doing that now). The price is fair for members of this thread too. Check it out Berwyn

I installed mine tonight. I had to go pick up some 65mm long 6x1 metric bolts to mount the rack to the frame through the provided bushings/standoffs. They ended up flush with the bottom of the welded on nuts on the fender brackets which they thread into. A 70mm bolt would have given me 5mm extra. I removed the rear plastic, removed the fender bolts and then reinstalled the rear plastic to drill guide holes from the bottom up through the frame of the bike. I then used a dremel tool with a filing bit to open up the holes to a little larger than 5/8" diameter to accomodate the standoffs.

I added a couple of picturers at the bottom of post #1 -- showing the shorter spacers ..

GsVs: That is a bloody sweet set-up. Any idea on the weight limit?

The most I've ever had on mine is a Med. sized tailbag with just a few pounds of stuff inside ... -- but it uses the same mounting points as the Pro-Moto and a few others and I've seen pictures where others riders have really loaded them up. !!

I called those guys and had them make up the small rack, plus add the rotopax holes. They charged me a few more dollars to add that to their program. I rec'd the rack and spacers, but just started looking for the bolts. Of course the two big DIY stores were of no help, tomorrow I'll check with the specialty places here.

A plug for the builders... this rack is cut very nice and clean, topn otch work.

you are spot on with that question. Not on the WRR but on other dual sports I've broken the subframe carrying fuel and a few other things. Now I admit that I ride the bikes aggessively offroad and I'm now very careful on rear rack loading. Just for reference I would take a look at the OEM rack which uses subframe braces.

Here is the Automotive Machine Supply Tri-Square Rack - their mid-size rack. GsVs pics are of the Big Rack - their large size.

Hey ....

Had a question on how I attached the tailbag to the rack.

The tailbag comes with built-in bungees - but I don't like to use bungees ! --- the tailbag also comes with straps that have a male end to attach them to soft panniers if used. You can see them on TCIproductsusa.com ..

I saw that TCI had made up some custom extension straps .. so I contacted them to see if thay could make up a female-to-female strap to connect the two ends on the tailbag together. See the pictures below -- they will show how these work -- and they work GREAT.

Tom at TCI was going to get some more female-to-female straps made up to post on his web site to sell .. but last I looked I didn't see them yet.

I bet if a couple more riders were to contact him to show interest he would make up some.

I just received my Automotive Machine Supply Tri-Square Rack. It included the different length spacers but no screws. Does anyone remember what size screws they used? I think I saw flat M6-1 70mm posted somewhere but not sure.

70mm. There are fixed nuts in the subframe. 70mm gives you just enough length to add a locknut.

I got them from Mcmaster.com. Part # 92125A258

Metric 18-8 SS Flat Head Socket Cap Screw M6 Size, 70mm Length, 1.00mm Pitch, Packs of 5

Also, the spacers are not the same length. Make sure you try it both ways so the rack sits right (I forget if the longer ones are up front or back).

Thanks gatorfan, that's exactly the info I needed! I may have the rear rack powder coated to match the Wolfman side racks that I'm considering. I'll post up some pics if I go that route.

In the meantime, I'll latch up my Givi E45 to handle my commuting needs. I really like the quality and versatility of this design.

What are the dimensions on this rack? I think this is the one I want.

Go to AMS web site. They have the specs for all 3 sizes.

maybe I'm missing something? http://www.automotivemachine.com/index.php?option=com_content&view=article&id=51&Itemid=56
