Well, probably more people gonna hate me than like for what I’m doing (even my wife said that I’m crazy and she like original version better) but I hope to share some info with few people who gonna find this thread useful Smile
Few months ago I found online picture of K100 modded by Retro Riders by Laurencno Brothers and I fallen in love.
I don’t know why, I said to myself this is what I want ! Period.
About 8 years ago we closed small ironwork shop upstate NY but all tools and equipment is still there almost forgotten, so I turned it for new home for my 93 K1100RS.
Originally I was looking to buy a K100 but couldn’t find anything in decent condition and reasonable price. After a few months of searching I was lucky to find 1993 K1100RS with 34K miles for $1500, couldn’t resist Wink
And here this story begins...

Hi, that's a fair project you've got in mind. Are you buying one of the Retrorides rear suspension linkages, or are you having a go at making your own? Reason I ask is because the Retrorides design is for a monolever back end, whereas your bike has the paralever.

Chris,
I purchased the caferacer bible from Retro Rides with basic info and some drawings and contacted folks with CNC machine to get an idea how much it will cost me locally but unfortunately cheapest I found was about $800 for the machining only. 7075 1” thick aluminum sheet to do the arm only was over $200, custom made brass bushings and water jet or plasma cut steal for supports additional few hundred bucks... since I was digging Pinterest every day searching for gadgets to my future project I found great company located in Slovakia. They sell that arms ready to go with all necessary elements including bolts, washers and nuts for probably 1/3 the price I would get here so I ordered from them, I couldn’t be happier with the machining and material quality !

Was it cafe4racer? - I bought a seat unit from them and was impressed with the service.
You will have to swap your paralever swing arm for a monolever though. Plenty of people have done the reverse, so it shouldn’t be too difficult.

Now time for fun part !  

K1100RS by wooboodoo Img_3621

Yea I know - safety first... don't do this the way I did grab some safety glasses.  

K1100RS by wooboodoo Img_3622

I had to extend the pipe to relocate the vin number and make additional support.

K1100RS by wooboodoo Img_3623
K1100RS by wooboodoo Img_3624

Now finally I can play with horizontal suspension arm, for the beginning I got some Chinese, cheap 300mm shock for welding purposes while I was waiting for the British NITRON NTR R1, I trust NITRON more than YSS and will not pay about $1K for Ohlins...


K1100RS by wooboodoo Img_3625
K1100RS by wooboodoo Img_3626

Clean and ready to weld, since I'm crazy about welds it gonna look like there's no weld  Cool

K1100RS by wooboodoo Img_3627

Time far worst part of this project, it took me almost a day to adjust the seat supports the way I like (accept) these... Wish I had somebody to help me.

K1100RS by wooboodoo Img_3628
K1100RS by wooboodoo Img_3629

Outer welds done, I applied some primer to prevent corrosion will do inner welds when take the frame off the engine but first I have to create some battery holder, still undecided which way to go...

K1100RS by wooboodoo Img_3630
K1100RS by wooboodoo Img_3631

I would say - not bad  K1100RS by wooboodoo 447221

Last week I got awaited shipment so finally I was able to install the shock, not bad but do I really like this color?  K1100RS by wooboodoo 652573
In the meantime I found the company Fast Bike Industries LLC and looks like they have in stock metalic black color spring for my shock so I'll order to see which one I like better.

K1100RS by wooboodoo Img_3810

Still trying to figure out how to hide this battery, alone or together with ecu? maybe better place for ecu gonna be under the seat? Idk but will decide next weekend I mean I have to finally because it takes too long... Will appreciate any suggestions maybe some pictures ?

Not really a fan of cafe jobs, but can’t fault the quality of your workmanship. Hope she turns out like you want. Interesting shock alignment - looks very horizontal - will it work?

Clear vision is overrated. As the celebrated sexist ballad tells us, The women all look prettier at closing time, and that probably is true for weld beads, and bike build, too. Laughing

Thank you sir, I hope as well ! Wink
As about the shock I’m glad that i choosed nitron, it has pretty wide stiffness adjustment range, I've tried it already and works well.
