    As for width, expect something in the 6' range. I have a Hannigan Classic latched onto my K1200RS; I asked Claude to leave just barely enough room to get the right-side hard case on (it can't be opened) and that put my rig at almost exactly 6' wide. I can't imagine an R12RT-based rig with a sizable car would be much different.

    Thanks for your input. I have a Aluma 638 trailer. It is 63" wide and 8' long. I would like to have the capability to use it if I have to.

    The R1200RT is now running great. I guess sitting in a stew of ethanol, water, and stale gas was too much for the fuel pump. New pump, it started right up. I have pretty much decided to buy a Hannigan Sidecar for it and have them attach it. We have to go to Kentucky first and pick model out that not only looks good but meets my wife's expectations of comfort. Steerlite, Lean Control and hydraulic disk brakes are also on the list. Last thing, I don't care for the "trailer wheel look" on the tub so I will be looking for something else.

    Hannigan can probably do a bmw R1200 wheel also, look at the adv model, get a swaybar DB

    I have a Hannigan Conte Classic on my K12RS, I think the track is 56". It just fits on my Triton 64" wide trailer, the left footpeg just tips up at the top of the trailer fender. You need to check to see if the RT jugs will clear. I'm not too far from you if you and your wife want to take a look at the car.

    This is with a short windscreen I made. The tall stock shield is mounted now if your wife wants to see and try it with the convertible top on.

    Rear BMW wheels can be ran on sidecars. The 4 bolt pattern that BMW ran for a while is a bit of a pain to run as the bolt circle is small enough that you can not mount the wheel bearings in the hub instead you must mount them in the end of the swing arm and build a special hub to also support the brake rotor. Or if you go with the newer 5 lug wheels we drill our hubs with two bolt patterns, the pattern for the automotive type wheel we run but also the BMW pattern so it is no problem at all to run a 5 lug BMW wheel off of a 1200 however FYI as lots of people read these posts for many years to come, some BMW's like the C650GT scooter have a smaller 5 bolt pattern, for these we have to drill a different pattern on our hub. Not an issue to do, just not some thing we keep on the shelve.

    We have done the Hannigan dual sport model (which is basically a Classic with a BMW wheel) on various bikes. We have also modified these to mount the same wheel on the sidecar that we do for a car tire conversion on the rear of the bike.

    Thanks for all your input. I looked at Sabrina Summers' Website and she is selling a BMW R1200RT with a Hannigan Dual Sport with the BMW wheel. I believe Claude put this rig together for her. I like the look - substantial but not bulky. (thesabrinasummers.com)

    I hear discussion about "Sway Bar". Necessary or not? Also, is a steering damper required?. I am waiting for some parts from BMW so this questions keep popping in my head.

    I'm very pro swaybar once you try one you won't be without one,Hannigan installs them as does Claude, his are a bit more substantial.Steering dampers are personal preference, they all shake a bit but some are scarey.Your throwing a couple bucks at that thing, I think the Sabrina Summers rig is gone, I also really like it's look.DB

    This would be a bit of an understatement. I'm not an aggressive driver, but the mods Claude made to my rig (including a bombproof swaybar that made the OEM unit look like a tinker toy) so greatly improved handling when pushing it thru mountain twisties that my fecal consumptive grin has become even more pronounced.

    We did our best to get the bike to run. After much consternation, I brought it to my local BMW shop. They have a new service manager and I was pleasantly surprised with his friendly attitude and knowledgeable approach. After a short while it was determined that a new fuel pump was in order. I guess sitting in a stew of stale gas, ethanol and water for 2 years, was not a good thing for the pump. I also found that they don't give those pumps away! Even though, he cut me a break on labor and I left happy. :rofl

    The bike runs and it sounds great! I am continuing to get the bike ready for it's trip north (on a trailer) to get a sidecar installed. We exhanged brake fluid, oil and filter, clutch fluid, trans oil, and finishing up on final drive oil. All the plastic Tupperware is off of the bike and I may leave it like that until the, subframe, sidecar, Steerlite, brake hose, is attached. I will bring the plastic with me though for it's test run.

    This project has been the most fun I have had in a while. I am looking forward to driving something a little more sophisticated than my Ural. I know, my riding lawn mower is more sophisticated than my Ural. Nonetheless, I can't imagine what going over 58 mph would be like. Heated seats and hand grips, adjustable lean control, cruise control, the list goes on. I will always have the Ural for on a off road though.

    Saw a picture of your new rig in another thread. Time for you to come back to this thread and finish the story. Tell us about the install, did you get the swaybar, any steering modification, how does she drive, are you happy or flummoxed, etc. In that other thread, the rig looks great right down to the matching jackets!

    Drone, you are entirely correct. I did not finish this thread and to be honest I forgot all about it. My bad. Old age sucks!

    In December, my wife and I drove up to Murray, KY to Hannigan Motorsports in my Isuzu NPR Box truck towing the BMW RT on a trailer. It took two full days to get there from Florida.

    When we arrived in Murray there were remnants of snow drifts on the ground and it was cold. The next morning we showed up bright and early at Hannigans. They took the bike in and they started to thoroughly disassemble it. It was a surprise to see that level of disassembly for the addition of a sidecar. The "Tupperware" was everywhere and pieces just kept coming off. I couldn't take it any more so we decided to explore the local area. Besides, I didn't want to make a pest of myself and it looked in capable hands.

    Even though Murray is a college town (Murray State), it is not what one would call "exciting", so we ventured out into Kentucky and Tennessee. We went to see the Elk and Bison at the Land Between the Lakes, we went to Paducah to see the Mighty Ohio River and we travelled back and forth to Hannigans to view the sidecar installation progress. What was only a week seemed like a month.

    I had discussed putting a Sport tub on but the sales people at Hannigans insisted that the Bandito tub was the way to go for handling and performance. I acquiesced and put the Bandito on. I had accessorized the rig to the max. Level control, disk brake, Steerlite, and 100mph Spoiler w/light. I brought my own wheel as I did not care for their version. I feel like it came our very well. It took a day and a half longer than we thought it would but we are retired, so what. Hannigan reimbursed us for the extra day at the hotel and food expenses. Nice people.

    The plan was to put it all in the truck but the rig was too wide so we separated it and put the bike on the trailer and the sidecar in the truck. It only took a short while to separate the tub from the tug. Putting it back together was more difficult but not impossible.

    There are a couple of bugs I have yet to work out with the rig. First is the "head shake" at low speeds and second is that the shocks on the BMW really are not up to the task. I am talking to Wilbers about new shocks and I have ordered a steering damper from Hannigan. My Ural has very little shake so I expect to get the same from this rig. I am also fiddling with tire pressure and will look at the tightness of the steering bearing. Hannigan test drives every rig and felt the head shake was within tolerance but after a tank slapper at 25 mph I am not convinced. It may also be related to the crappy BMW shocks and springs.

    That is it. It cruises at 75-78 mph no problem and I have bonded with cruise control. It is awesome. The heated seats and handgrips are nice but fuel mileage (31.8 mpg) is almost as bad as my Ural. The car is comfortable and very stable but also very wide. All in all, I am very happy with the rig and I am taking it to 'Sidecars in the Smokies Rally' later in the month.

    This is a picture of the completed rig. I get almost as many thumbs up as I do with the Ural. It is nice looking.
