These digital speedos can be used on many types of vehicle, but they do not have EC type approval ("E" mark), German type approval, TÜV test certificate or any other approval mark. Therefore their use on public roads is not permitted under the German Road Traffic Licensing Regulations (StVZO) They must only be fitted to your vehicle and used for race, competition and show purposes (classic and collectors' motorcycles). Before using them on public roads, it is obligatory to first obtain individual component approval at your local TÜV test centre, or equivalent. We give no guarantee that such individual component approval is possible. You should also refer to our information about licensing regulations (Item 2), e.g. in our Standard Terms & Conditions. This also applies outside of Germany.

"Tourenfahrer" magazine gives its assessment of the Sigma MC1812:
"The 'MC 1812' from Sigma provides information about torque and braking distance in addition to the usual parameters. We tested this versatile motorcycle computer. At our test centre, we have been using technology from 2D-Datarecording for many years, so the Sigma computer (which will only set you back EUR 60) had a tough act to follow when we tested it against the professional equipment.
Both devices were installed on the same Honda Transalp for the purpose of the test. With the MC 1812, the diameter of the front tyre has to be saved in the device. One of the magnets supplied is then installed in a suitable position, preferably on the brake disc, as the pulse generator. Then all that's left to do is to align the receiver, and we're ready to go. The receiver is subsequently fixed to the fork tube using two cable ties. A universal mount serves to attach the computer itself either on the handlebar or in the cockpit. Then it's off to the test track. The display of the MC 1812 is easy to read, and the contrast can be set to several levels. Once all the measurements were taken, the data were compared.
With the MC 1812, the results are displayed immediately after measurement. If you press the Set button for four seconds, the last measurement is zeroed and can be taken again. Our results show that the Sigma computer matched the professional device exactly down to the decimal point. It was only with the elasticity measurement that we found a deviation of five percent. However, with a more powerful motorcycle, it would no doubt be a different picture with regard to the discrepancy in measurements, as the Sigma MC 1812 uses the revolutions of the front wheel as the basis of measurement. If the front wheel lifts even minimally off the road surface, the result is no longer correct. The computer from 2D-Datarecording takes its measurements using GPS via satellite, so a lifting front wheel does not influence the result. Verdict: The next time you go to safety training and want to monitor your success rate in the braking exercises, or to compare your reaction time at the beginning and end of the season, the motorcycle computer from Sigma is a good choice. Furthermore, different elasticity values, both solo and with luggage or a pillion passenger, provide a good indication of the time required in theory for overtaking manoeuvres.
