If you cannot find soft ties at your WalMart (they are not available in mine) You can order them from Sierra BMM online. I got Ancra Soft Tie Extensions there over a year ago and they have held the LT on my trailer all the way to Wyoming and back to Chicago last year, and to Arkansas for Spring Break last month.
Yes, I admit it. When I only have a week or so of time, I cannot chance the weather. Big as they are, the bags on the LT do not hold a week of laundry for two, and I would rather ride the bike than wash clothes, any how.
You will need to order two sets if you order these on-line.
BE Sure to print the PDF and follow the directions with care. That brake line on the front is hard to see at night,
I used to be able to find videos of the BMW tie down online but not today.
BMW used to recommend not using ratchet straps.
The BMW staff tie down procedure was that two men did it. One leaning the bike and compressing the suspension whilst the other winched it down with the tie straps. Then bouncing on the bike to compress the other side whilst the other winched on the straps. Bike was really compressed down on its suspension when they had finished.
That is fine if you have two BMW staffers with you. I wonder what that would cost. It also does not work if you have a wheel chock. I found a nice low-rider trailer. The first thing I did was to cut off the curved steel receiver for the front wheel - it was too tall for the LT's front wheel plastic. I found a six inch wide chock on-line that I bolted onto the trailer.
With that, I can just drive the LT up onto the trailer into the chock, and step off and put the tie-downs on by myself. I do, by the way, mount the soft-ties before I drive it onto the trailer. But with the chock (and the bauxley chocks are the better, but they don't have a model that fit), you cannot tip from side to side.
I did buy the ratchet tiedowns at WalMart. The sell them in four packs.
This arrangement lets me get the bike on and off alone when necessary, in about 5-10 minutes, and has taken us to Wall, SD and the badlands, two days riding in the black hills on the way to the BMW Rally in Gillette, over to Cody and the Chief Joseph pass, and then it got the bike all the way home through SD, Nebraska, Iowa, and IL, in time for work. A dubious achievement, that last part.
Same thing this March. Drove out of the Chicago snow and rain to the 65 degree March air in Arkadelphia, Ark. Put 1,500 miles on the LT in AR, OK and LA. then drove home in the rain for 8 of the 12 hours back to Chicago with the LT safely on the trailer. I figure the trailer gets us about an extra month of riding that Chicago's weather does not allow for.
By the way, when its on the road, the LT is the most stable bike I have ever ridden in the rain. 60 of those 1,500 miles were in a real downpour. I was a little worried about lightening driving over a dam in the thunderstorm, but not about riding two up through the hills in the rain. For us, trailering the bike the best of both worlds. Yes, grey hair is a factor. Hope this helps.
