I agree. I don't even know what is the latest. Instagram has very few Sachs Roadster hashtags
Hi, I have created a facebook group just for Sachs Roadster 800/B-805 fans to compliment this site and Lothar's site.
Just a small group, but with interesting and rare pictures of modifications and customised bikes.
It is a private group, because I know not everyone wants the whole internet to know what toys they have. Sachs former Technical Director/CEO is also a member, so you can show off to a small and knowledgeable audience. The link is below if interested.
I thought this will be of interest. It's in great condition and I feel quite a fair price

maybe the Brembo saddle fits. But here in Germany you can't just swap it out at random, especially since it's a vital part. This must be checked and approved by an officially recognized expert!
Sorry, i forgot about the TUV
Hello, here is the most recent list. Looks like in the last 15 years 600+ sachs 800s reduced to under 500. I think that is quite good result. I have also seen a few converted the cafe racers and scramblers (even a B805), which I'm less happy about because it seems like destroying history.

I had some discussion with Hartmut Huhn and will publish full info in due course. The sort story is that it is VERY difficult to bring a motorcycle to market and is no small success. In the meantime, let me share some interesting facts;
- Egli did indeed design the frame and gave permission for it to be reproduced by MT in Italy
- There were other Suzuki engines available, including from TL1000 and Hayabusa, but management changes and politics at Suzuki got in the way
- The Sachs Roadster 800 origin was the swiss version of the VS800GL, with the carb and exhaust changed to release more power and also additional bracing metal on the swingarm to strengthen it.
- There were many manufacturing challenges, where tooling cost needed to be wisely chosen. For example, plastic panels were pressed not extruded.
- The blue color of the Sachs Roadster 800 was what was available rather than chosen for particular reason
- The parts, being low volume, were a challenge to procure and work with many established European suppliers who were free to sell to others. This is the reason of many of the current parts challenges
Needless to say Hartmut Huhn is a lifelong motorcycle enthusiast, engineer, racer, builder and has a large collection, including a very nice 70s ducati 900ss.
" he says;
For my motorcycle love: I was always riding and racing motorcycles all my life and do it still. My racing bikes were build and tuned by myself and I was quite successful in national championships, but i could never race a complete season (see above). I raced also superbikes with international license and 24h endurance races.
In my first years Honda was so much advanced that I was a big fan. Then I fell in love with Ducati and from 1978 I always rode Ducati (and other Motocross/ Enduro bikes), actually the Streetfighter.
Then I have a BMW R 90T and more than 40 other older bikes, Ducatis, Aermacchis, Laverda, Guzzi, Enduro/MC bikes and some Sachs and some of my former racebikes.
I am now restoring old bikes (and sometimes cars) and sourcing parts, one of my Ducatis 900SS is actually for sale https://www.themotorcyclebroker.co.uk
many thanks!. pm sent on intruder site
Hi, Yes please. I would love the drawings. I have a fabricator friend that will be able to help me out. Please message me
Hi, I really want a main/center stand for the Sachs Roadster 800 or Sachs B-805. Happy to pay up to 200euro. Any condition. Please let me know
Hi, just some info that may be of interest. I read that the Sach Roadster 800 and 650 frames were designed by EGLI (known for their famous racing Egli-Vincent, and are kind of a Swiss Bimota).
Anyway, I thought it incredible that such a prestigious frame designer's name was not mentioned more.
So I contacted EGLI to confirm and yes, the Workshop & Technical Director Jürg Lindenmann still remembers the Sachs Roadster.
EGLI also confirmed they designed and built only one prototype. I then read MT Srl in Italy (https://mt-italy.com/steel-frame.html ) manufactured the frame, which I guess are copies from EGLI's sound design. MT Srl make frames for Ducati, Aprilia, Moto Guzzi, Husqvarna and others in Europe
Side note, the Sachs Roadster 800 prototype pictures do appear to have been clay modelled by TargetDesign on a VX800 engine/frame before eventually using the VS800GL engine in production. I read the switch from VX800 to VS800 was simple because the VX800 ceased production
Here's their website if interested
Personally, I'm going to attach the EGLI pin badge on my frame
Hi, Just sharing this video I found that shows a lot of Sachs history (although no audio). Around 12 minutes there is a rare sight of the factory assembling the Sachs Roadster 800
I guess those fuel tanks are perhaps from a Hercules model or one of the Chinese models they were importing. It's the only factory pic I could find and now I can't find the source anymore. I recall the pic was from a factory open day as the city had some kind of celebration for it's industrial history
I figured these people might be retired and may no longer be available to ask. So, should end the endless speculation.
A few things I have discovered since.
The original prototype for the Sachs Roadster 800 is currently in the Museum of Industrial Culture (Museum Industriekultur), which is nice
Also, the Sachs Beast Prototype I believe lives in Mr Huhn's office.
I did find only 1 picture from the factory. These were made in the Hercules Motor Works

Here is a facebook post with the other rare pictures I collected over time
Hi, I've been reviewing these interesting documents
"In order to meet the EURO 1 limit values, Sachs has incomprehensibly shortened the carburetor springs in addition to the SLS; an uneven throttle response is the result. With the optimized carburetor modification, there is torque without dips over the entire speed range up to In addition, ..."
My questions are
1) Regarding "torque without dips over the entire speed range". Are we sure the carb is the cause? Apparently there is a microswitch on the front carb which alters ignition timing. Evidence from here http://vx-faq.thevuelta.com/. pasted below (I have since just disabled the switch)
2) Regarding being bad to shorten the carb piston spring. This being done together makes me think that Sachs wanted to
a) reduce engine braking effect by making slide return down at a slightly slower rate (the Sachs doesn't have the VX800's slipper clutch)
i.e. smaller hole in slide piston
b) not be detrimental to quick throttle response, ie shorter spring, less preload resisting vacuum
c) for emission purposes, produce more torque lower down the rpm range.
Furthermore, I think this is why the prototype Sachs went from 160/60 rear tire to a 160/70 rear tyre, to reduce the RPM and therefore emissions when being tested
I have no proof of these carb considerations, but will add them to the questions I give to former Sachs R&D Director Mr Huhn
What do you think?Code
- "6.6 OddSwitch
- Recent European models (definitely the German models, perhaps others)
- have an unusual switch on one of the carburetors that closes when the
- throttle is fully open. Harald Bilke made some inquiries, and found
- that it's part of a system to reduce noise emissions!
- "The switch is necessary to keep the noise emissions just below the
- threshold. It engages only in the 3rd and 4th gear when turning the
- Throttle fast to "full open" and between 40 and 60 km/h. (This is
- the setup how the measurement is done - hint, hint ;-)) The
- ignition timing is being changed - so full power is released a
- little bit later. This is enough to pass the microphone and having
- a little more distance between it and the engine the dbs are lower.
- As I recall now I could feel the "hickup" myself. But you have to
- turn the throttle really fast."
