  • My XS just broke -- in half!!!

    So much for the 4th of July adventure ride. I was going to ride my sidecar rig with both my Springer Spaniels across the Magruder corridor along the Idaho-Montana border. This gnarley gravel road goes ~130 miles through the Bitterroot Selway wilderness area. Fantastic views tho' there are still many snowdrifts above about 9000 feet.

    I rode the several hundred miles to the start of the trail without any problems. About 40 miles in I saw a good spot to water the dogs and started to slow down. All of a sudden I there was a pop and I was frantically shifting my weight to keep the rig from going down the embankment into the river.

    BOTH frame members had snapped in half in front of the engine right at the bottom of the fairing mounts. Without this support I now had two tires and four exhaust headers on the ground. I managed to get stopped and maneuver the rig into a small pullout before the spark plug wires broke.

    I guess my karma was fully charged since I only had to wait about 6 hours for rescue. Amazingly a gal in a pickup towing a large trailer (from a rafting company) came by and we managed to drag the now disassembled rig into the trailer. Arriving back at civilization I managed to reserve a u-haul truck in another town 5 minutes before the store closed. I then came across a good samaritan biker who ran me a hundred miles to pick up the truck.

    The dogs and I are now back at home. I'm glad the bike didn't break any farther up the trail (where few people go) or at high speed on pavement. I guess I'll need to render assistance to a few other people in distress to rebuild the karma factor.

    I've pretty much figured out how and why this happened and I'll be posting a few links later to pics of the damage and a few recommendations on how to keep this from happening.

    Enjoy,

    Rob

    Holy **** Rob! I am glad that you and the pups are OK. I have one bike (81H) that keeps breaking behind the weld by the rt. side seat mount.

      don't you just hate or love those wardrobe malfunction induced stranded hopeless feeling close calls?

      those feelings never really leave you, they become you.


      looking forward to pictures...

        I feel SOO much better about almost everything that has gone wrong on my bike while riding after reading your post.

        YES take care of that Karma...I took care of you!

        I too can't wait to see pics. (like a trainwreck, just can't look away)

        GLAD you and your pals are OK!!!

          Wow, is about all I can say. well, I really like your attitude. If I had to "wait only" six(6) friggin hours after my motorcycle had broken in two..I would have guessed my karma had run out, but then I live in Michigan and we don't have true wilderness. In my town (Saginaw) wilderness is being broke down on the wrong side of town. Can't wait for the pictures.

            Here are a couple pics of my XS with a velorex taken a
            couple years ago on the Magruder in JULY!!

            I rode the several hundred miles to the start of the trail without
            any problems. Here's pics of my pups wanting to "get-the-show-on-
            the-road" and at the pass about a half hour before the accident:

            (36K)

            (53K)

            About 15 minutes before the wreck I stopped to take this pic with
            the signs warning that the road will begin to deteriorate soon. I
            should have noticed that the bike was starting to lean toward the
            sidecare. I think the right half of the frame was broken at this
            time.

            (43K)

            These pics show why I should have fabricated a bracket and used the
            main fairing mount bolts for the forward upper sidecar strut. The
            frame broke right at the bottom of the lower fairing mounts which
            are usually just attached with hose clamps but in my case the right
            side is where the velorex style frame clamp was. I think the
            sidecar strut and the bouncing of the fairing concentrated the
            stresses right here, thus breakage!!

            (46K)

            So..... now I guess it's time to start stripping a couple rigs down in preparation for a frame swap. It kinda seems to me that it wouldn't be a good idea to try and weld the frame back together.

            Later,

            Rob

              WOW...You do put it to the test! That is a big load for a gnarly road. If you DO weld it you might consider using armor plating!

              Again...you are SO lucky that didn't happen at 70mph! This might be a memorial thread!

                glad to hear you are ok thank god you were not on a freeway somewhere! my brother had a new cbr and was on I84 in oregon when his frame broke sorry to say but he is no longer with me. your frame looks like it broke evenly on both sides I just cant see both sides breaking that way. I have a 1980 rolling chasis if you need on and yes it has a tittle

                  Jesus Chrysler! You're a lucky man!

                  Damn shame about your rig. When you're ready to rebuild, let me know and I'll give you the drawings for one of these, ready to take a 3/4" thread clevis or eye from Dauntless.

                  http://spaces.msn.com/andnewhome and scroll to the April 30 entry to see details.


                  You might remember I was interested in your old chair but didn't wind up winning on Ebay. As I told you then, I'm in the process of building my own chair so I just happen to have fresh engineering data.

                  In fact, PM me if you want me to just whip one up for you. Mine won't be pulling a hack until late September at best.

                    welding the frame

                    ROCKJOK, Glad you and the PUPs are OKay. This was quite an adventure, not to be repeated. Pictures of the landscape are great. Careful welding by good welder will work on thin wall tubing however the integrity of the member will be weaker. when you make the swap to the newer frame add a split reinforcement to the frame where the farring and side car mounts are to distribute the load and stress. The split tubes should extend about 2" before and after the mounts. this will add thickness and stiffness to the member, GOOD LUCK on the reconstruction.

                      I don't think you should try to fix it, not only has it broken in at least 2 locations, it has to be bent in countless others. Unless you want to rebuild each bend point on the entire frame, it's just a bad idea.

                      What exact damage occured continuing to safe parking while dragging motor, header and sidecar?

                      What stress was applied to the other mount locations when this had partially given way, and did it cause any collateral damage?

                      Exactly what damage was done to the rest of the frame as a result of this unfortunate accident?

                      No way I would bet my life or my dogs lives on fixing it unless I could fully answer all of the above.

                      Gratuitous Sidecar talk follows, won't interest most folks:

                      I visited Dauntless Motors new location, (less than 5 miles away at their new location)

                      Bought some parts for my XJ hack project, Jay thinks my upper front design is fine, but he didn't care for the aluminum slug, until I explained the structural aircraft aluminum alloy from Boeing that I am using, it's rated for wing-spar use and is the toughest alloy I've ever tried to machine.

                      I also saw the difference in Jay's strap clamps and the Velorex universals. Jay's won't deform your frame rails in any way, if you're using any other Velorex straps, please consider switching to Dauntless straps on your rebuild. (I bought one today for my lower front)

                      I'll try to get up some better detail pics on my site later today.

                        That looks like a special front end. I have a special frame as well, Rob. sidskids @ earthlink.net

                          Breakin' up is hard to do!

                          Hey Rock,

                          BTW, I editted your post with the photos so that they show within the message!

                          Dayam!!! AndNew is probably right with regards to trying to fix that frame! You'd need a frame jig to be able to verify that everything is aligned properly! Also, with that much stress breakage, no telling what other joints are also worn and weakened, and could be ready to fail!?

                          With a NOS frame, at least you should be getting one that is intact! Then you could add some additional bracing and welded joints to bolster the higher stress points that you have NOW found prior to putting all of your components onto the new frame!?

                          Also perhaps you may need to re-evaluate the weight and stress the side car is putting on your frame, is it too heavy, carrying too much of a load in it, is it not aligned with the bikes wheels so that it's pulling away from the line of travel inducing stresses at a strange vector??

                          Makes my little bent frame inconsequential!

                              I would also say the right side failed first and soon the left down tube followed. It broke directly below the side car mounting point on the right down tube. I would weld in a (same diameter tubing) cross brace, tying both down tubes together at that stress point. The load on your rig is considerable and the shock from the many rough road (sic) that you travel are telling you something? Check to see if the interior of the broken frame members are at all rusty? Many times old steel bicycle frames used to rust from the inside out. A protective measure is to drill a very small hole in the tube somewhere away from a stress point and squirt in "fogging oil" the oil will spread itself throughout the tubes. You can then either reweld the small hole(s) or plug with silicone. When looking at stripped XS11 frames I see too many open spaces. Even without side hack mounted I feel the need for more frame braces. Solid engine mounts would also help frame rididity.
