    Lurked here for a while now and got some usefull info and ideas.I built my first leaner twelve months ago and attached it to a Yamaha XJR1300. It was quite sucessful and we did some 10k with it ranging from track use to touring.
    Old age caught up with me and so a new bike saw the need to build another sidecar. we found some more information to create a better handling unit and when attached this unit allows me to take hands off the bars at 100kph and it tracks dead straight.
    Due to it being a cruiser style bike the lean angle is nowhere near that of the XJR but is still a lot of fun to ride.
    We are just doing some shakedown rides at the moment, but come late December there is a 10k ride across Oz and back for five weeks.
    Cheers for the great sight and freedom of info for all to acess. I will post some photos of it attached to the bike later.

    This was the set up of the chassis before starting on the body. I had seen a similar swingarm and because it is narrower than a conventional double swing arm decided to go this way.
    After the first run the swingarm needed another brace, which was added and now performs perfectly. The shock is a progressive fully adjustable and it does an awesome job. Riding last night with a passenger for the first time the ride was super comfortable.

    Really like the looks of that sidecar body! I'd love to see more pics of the build if you have. A bit confused by the swingarm from these pics, brightness of paint makes it difficult to see definition. Curious what that cylindrical thing in front of the car's shock mount is, almost looks like it has wires coming out the bottom and passing through a grommet into frame.

    Have you thought about adding a diagonal brace inside frame box from right front to left rear at chair's wheel, to help control flex and distortion?

    Wow, that looks realy nice! Good job!
    Can you post some more pics of the swing arm and suspension set-up? I've build a leaner last March and I'm planning a second one. Good input is always welcome.

    Thanks for the comments guys, i will try to answer your questions and add some more photos.

    The swing arm was a copy of one i saw in a photo and liked the idea of the lines and narrow width. As long as the push is direct on the shock it will work well. We may add an adjustable set up to the top link so as to have more adjustment depending on the load.

    This was the start of the swing arm.

    So on with it,

    Continuing with the English wheel to form the back, what a learning curve(pardon the pun)

    And the finished back with a fair bit of planishing and bog to go.

    A better shot of the swingarm design.

    Well, I must say I'am amazed, even astounded! Looking at the first couple of pictures, yes, I was very impressed. Clever fella, great design and some very nice fiberglass work.

    WHAT??! ALUMINUM!??!!! WOW! I could hardly believe my eyes, had no idea! I quickly moved from impressed to genuinely humbled by your fine craftsmanship! Most excellent and I'm even running out of exclamation points! Beautiful....thanks for sharing!

    So it was finished and we went on our trip to Tasmania. Some 4000ks to Melbourne and onto the ferry across to Tassie. We did about 5500ks touring the island and the ride and handling was superb. This photo was taken on the last day about eight hours before the return trip to the mainland.

    At about 10.00am that morning we met a railway crossing in Devonport and this happened.

    And this was the outcome.
    http://i153.photobucket.com/albums/s201/hiho53/mobile436_zps04d4db64.jpg

    I copped three broken and several fractured ribs, and the wife got a 50 staple cut on one leg and her left wrist is shattered in about forty pieces.
    The moral of the story is dont build a sidecar too low and if you do dont overload it.
    We have started the new plans for the next body and chassis. We will recover the swingarm, wheel and shockie off the old one. Everything else is bitter and twisted.
    Our holiday, which we have renamed an adventure, ran about $10,000 over budget. This was partly due to the wifes father passing away and a return flight to Thailand for the wife, then hospital accomodation, hire car, transport for the wreck. Flights back to Perth, instead of riding.
    But, it was a great trip and we are already planning another in Tassie in March 2015.

    Wow! That's terrible news. Not much to laugh about there. So when the subframe hit the railroad track did it make the rear end buck up throwing you two in the air? Did your wife get her lacerations while exiting the sidecar, or on impact with the ground?

    The only kinda good thing I see outta the whole affair is that the newspaper reporter characterized you as a "middle-aged couple". If it was me and my wife, they'd probably say "a couple of old codgers". Bu then again, I'm two years older than you so maybe that's fair. :D

    Wow as well! Thanks for the reply. Sorry to hear about the mishap and hope you both had a thorough healing.

    Just starting a leaner build and yours mimics, closest to what I had in mind. Note taken on ground clearance! Railway tracks are one thing I had not considered. Your second run at this should be interesting as the first was very impressive. Subscribed so please post any progress here or a link to it.

    I do have a couple of questions if your up to it? Main hoop/frame tube OD, wall thickness, material, basic dimensions and/or sketches, did you do your own tube bending?

    BTW, the trailer in the pic looks very interesting!! Any info available on it?

    What a tragic loss, and on top of your dear wife's other personal loss! Very sorry to hear and the best to you both in mending up from your injuries.

    Still, others have not been so fortunate as to even survive such an accident so despite appearances, Somebody seems to have been watching over you. Having survived, the future is still bright and hoping the best of it for you both.

    On striking the rail the bike tried to keep going which tore the sidecar off. Because of this i was thrown over the handlebars and the sidecar rolled, throwing my wife out. She cut her leg on impact on the dashboard in the sidecar.
    This is the rear rail folded forward from the bike travelling on.

    This was the front subframe. It found the weakest point, probably for the best. If it had all stayed connected the result may have been a lot worse.

    With a lot of what ifs and other thoughts could the construction have been better? We think not. The type of tube and fittings, the welding and parts used had performed perfectly. I wore out two sets of tyres on the ride due to agressive riding on the twisting roads of Tasmania. One section has 99 bends in a mile. I had ridden this unit at the track before leaving and there were no issues with scraping or handling at all.
    I have to put the accident down to mainly overloading the sidecar and some fault with the road layout.
    What have i learnt? The next sidecar will have an adjustable mount for the shockie so the ride height can be adjusted according to the load. And maybe i should start riding like its a cruiser with a sidecar, not a sports bike. But where would the fun be in that. :D

    Just ran through your pics. Nice tube bender! Nice shop! Looks like sch 40 black pipe and fittings?

    Wow, just wow!

    The precise and exact Physics of what happened second by second will forever be a mystery for sure. Impossible to know how weight distribution, exact speed, balance, body position of riders, tire pressures, shock settings, precise part of rail crossing that was struck, by what and when, and all the other variables resulted in this truly miserable outcome, but thank God you kids are ALIVE TO TALK ABOUT IT!

    Unfortunately our best lessons come from various misadventures and/or mistakes [that I'm so very willing to make] so the next build may somehow look forward to preventing mishaps. Still, hard to tell if it was any fault of the outfit, setup or whatever that directly caused this, which is in many ways doubtful.

    A rail crossing where this was even possible to happen at any reasonable speed is poorly designed, poorly marked and poorly maintained. I noticed in the article how quick the authorities were to defend the innocence of anybody but you guys! Me, I'm far from convinced!

    On some local routes here, that I have no choice but to travel, there are a few rail crossings on main thoroughfares that are absolutely inexcusable for condition. At 8-10 mph they about send me through the roof of my truck yet there's no indication they're so teacherous! They have compound dips and rises that just don't work together and never could. Simply a piss poor design with lousy workmanship on the part of the highway guys and the railroad guys who are NOT on the same page! On other properly designed and maintained tracks, driving in the same truck, I can cross at 50 mph with hardly a bump. So it can be done, or it can be screwed up. In your case I strongly suspect the latter...

    Wow :eek1 .Good to hear you and the wife survived that and are on the mend :clap:clap.
    It could have turned out a lot worse by the looks of the photos .
    Looking forward to seeing your new build :1drink


    The bloke looking at the trailer in your photo . Does he ride a sidecar ?
