Anyone know how much weight the rear pegs on an XB12Scg can hold prior to failure? How much side force prior to the rear peg brackets or mounting bolts failing? | ||

bolts should be easy to reference, simply look up the bolt spec according to the stampings in the head. Graded bolts are widely published as to tensile/shear limits. My guess...the hardware is the weak link. Find the bolt spec, you've got your assembly limit. | ||

My guess...the hardware is the weak link. Find the bolt spec, you've got your assembly limit. When you drop a bike, the pegs snap off; the bolts don't break. I'd think the cast aluminum foot pegs are the weak link. An adult can stand on one peg while mounting the bike without it breaking. Maybe ~200 lbs would be a safe load for each peg? You could always use Calvin's dad's design method:   (Message edited by Hughlysses on July 30, 2015) | ||

I can attest to having a 280 lb gorilla(a son) use the back pegs.....but then I had a passenger in Daytona for one ride that was over 300, I don't know if he even used the pegs, he kind of just stepped over the seat.  I would think the weight rating would be the same, or close, to that of the Uly. I agree with Hugh. The bracket will snap off before the bolts ever bend towards the breaking point. | ||

Ya mounting sliders? Tool boxes? A picnic table perhaps?  | ||

Harlan! Ning ning ning, we have a winner. Simple Bob style trailer. 10" wheel. Looking at using chromoly/4130. If I'm not using aluminum to keep the nose light I want to attach to a sprung location instead of the rear axle.simplest mount point I'm seeing would be the rear foot peg brackets.weight goal it a sub 80 pound mono wheel trailer with a normal load of less than 70 pounds. Up and down pivot at the pegs. Side to side just behind the rear tire with a head tube leaned forward at ten degrees. | ||

I could see an arched bracket, similar to the rear one on the Uly's rear under fender HB bracket, that goes side to side arching over the tire. Pretty strong reinforcement, in a world of not much to bolt to, for the hard bags. | ||

Very nice Vern. I've been taking measurements for an arched bracket attached with pins in place of the rear foot pegs. It arches up under the cheese grater and also fastens to the three bolt holes under the license plate. I plan for the forward vertical pivots for the trailer to be straight out the sides from where the foot peg pins are now. I'll weld those pivot points onto the arched bracket. The bracket will be 1.000" O.D. tube. | ||

I don't want it to appear that I had already thought of the arched bracket. Thanks for the idea Vern. | ||

Maybe it possible to make a small kind of triangular frame with hitch point that mounts on or in the holes from the rear axle with a rod through the axle and some leveling brackets with rubber stops that rest on the swing arm so it can not tilting forwards and backwards. | ||

See pics below on this page, http://ukbeg.com/forum/viewtopic.php?f=5&t=19643&s tart=30 There was a guy who was pulling a trailer with his Ulysses (it suppose that there are more pics of it on facebook ,but I'm not on there so ) Maybe this could help you in some way!? The thing was that the trailer was to low to the ground ,so it was scraping on the speed bumps in the road! and there are a lot of those in Holland | ||

You are welcome. Like Judge Judy says "they don't keep me here because I'm pretty!"  | ||

 There are factory built units out there that use the rear axle on the bike for a mounting point. That leaves only one end of the trailer suspended. Do you want me to haul your beers for you in that? I can see wearing holes in my camping gear from the constant jolts. Just a few inches up and forward are the rear pegs. I do not use them. If the trailer is mounted there it will have suspension at both ends without an increase in unsprung weight. OEM suspension settings are wide enough to let me still adjust the bike for proper handling. It is going on a Buell; it has to corner well. With my weight loss and the Scg being lighter than the XT, my loaded weight will still be less than the empty weight on the Uly. Don't matter what laws they write, you won't be kept around for being pretty.  |
