Hello, My name is John and I am new to this forum. I wish to converse with one or more people that have built a sidercar rig utilizing a K-100 RT. I have access to a URAL sidecar, in excellent shape however my 1984 K-100 RT will need some love.

hiya john .....welcome to the forum.

there have been some posts about side cars before

darned if i can find them just at the moment ....

but ask away if you have issues ...there is always someone with the experience of doing it before .

Hi John welcome to the forum as charlie stated there has been a few post's about sidecar's by sidecarJohn have a gander around this section of the forum and lets see some pics sounds interesting.

Hi John, welcome aboard. Lots of good help here. That bike will be a lot more stable in the snow with a sidecar on it.

Hello,
The K100 is regularly chosen for sidecar duty using a variety of sidecars, including the Ural one. Several issues, but can be overcome. The most obvious one is the need for a sub frame that attaches to the bike, but specifically provides fixing points to attach the chair.

Send me a personal message if you need specific advice.

Welcome Sidecarjohn, my only question is how the hell you steer those things. I'd be keen if I thought I could go around a corner.

interesting John - thanks for sharing

Hi John.

What is it with sidecars? I could never understand the fuss.

But that's what I like about motorcycling: horses for courses.

Hi John,
I thought I sent a reply yesterday but it's not showing up here. Undoubtedly, I pressed the wrong key or something. I have a '85 K100RT stripped of all the fairing plastic. It's attached to a 1970-something California Friendship I sidecar. The sidecar is on a new frame as I ruined the original frame while being too aggressive on a forest service road near here. The subframe on the bike is necessary, otherwise there's no place to securely attach the sidecar. The accepted advice about steering is to set up the rig and see how it goes. Mine was extremely hard to steer and there was a tank-slapping wobble at low speed (controlled pretty easily by a firm grip). Both characteristics are common (but not always) without some sort of mod to the steering geometry. I bought the Steerite triple tree conversion (if you google "Steerite" you should find it pretty easy). The difference in steering is huge. No wobble and general steering is very managable. There are other steering mods out there, most of them much more expensive. I'm very happy with the Steerite. I also just installed a rear wheel car-tire conversion. It's a custom rim suitable for a car tire. Rear tires tend to burn up very fast on sidecar rigs. If you figure upwards of $150USD for a motorcycle tire which might get less than 3,000-4,000 miles, compared to a car tire for about $50 which will get upwards of 15,000 miles, the choice gets pretty clear. But, if you're not going to ride the rig very much, the conversion might not make sense. I got it from Claude Stanley in Pennsylvania and it's about $800. Anyway, I'm happy to chat about sidecars, K bikes, etc. Let me know if I can try to answer any questions.

Hi there. I too am new to the forum and have been considering a K bike sidecar build. Several of the points raised here have also been on my mind but first things first I suppose. 1) with suitable subframe add ons, does the K100 lend itself well to outfit duties?.. 2) Can anyone lead me to info on the do's and don'ts of K bike outfit buidling.? Any assistance is greatly appreciated.

Hello mate,
I've been running my K100 RT and homemade sidecar for several years and well over 150,000km with the chair attached. Yes, the subframe is necessary...build it strong and don't be afraid to over-engineer on all aspects a bit. The K100 is a fine and strong motor for the job. The single sided swingarm is less than perfect for the job as lateral forces come into play when the chair is attached. Personal advice? Do the splines religiously and change the final drive fluid very regularly as well.

Sean.

Welcome John, sidehack, goodluck, some are successful. Have fun, great forum this.
