Description

The MOFESSOR is an automatic chain oiling system – developed and produced by BEROTEC GmbH.

Practically relevant functions, a compact design and high-quality details combined in one easy-to-assemble overall system:

  • Intuitive operation: Lubrication amount freely selectable in 10 stages
  • Rain or off-road trips: spontaneously increase oil volume at the touch of a button
  • Temperature control: The oil quantity is automatically adjusted and is therefore independent of the ambient temperature and the season
  • Innovative fastening system: Simple installation of oil line and application nozzle
  • Positive effects on the drive chain: Less friction means less wear, the chain tension remains longer, significantly longer chain life and more power at the rear wheel or lower fuel consumption
  • Range: ~ 5000 KM (standard) / ~ 10.000 KM (long range)

 

In the 4th generation the MOFESSOR is equipped with our proven control unit. Additionally there is a new and innovative holding bracket for the metering valve, a new design of the oil tank and the control voltage cable has an new comfortable connecting terminal. We also added new model-specific connectors.

 

Made in Germany


Details

The electronically-guided chain lubrication system cares for your chain automatically and unobtrusively.

On the compact control device of the MOFESSOR, the oil quantity emitted can be adjusted through 10 levels.   The rotary switch allows for oil usage to be set as required. This varies with assembly situation, motorcycle type and intended purpose and usually needs to be set only once.

The lubrication process is carried out through the controlled opening of the metering valves using gravity. The electronically-opened valve is sealed when there is no current and allows for oil flow to be safely interrupted when a motorcycle is parked.

With help of the rain switch, the driver has the possibility of pressing a button to increase oil usage eightfold while driving through rain or off-road.  The switch is operated manually. When rain mode is activated, an integrated LED displays a visual notification.

To ensure constant oiling independently from exterior temperature, the control unit constantly measures environmental temperature. Independent of exterior temperature, the opening time of the metering valve is automatically adjusted. This prevents that in cold temperatures too much or in warm ones too little oil is placed on the chain. It’s necessary because the viscosity (fluidity) of the oil is strongly temperature-dependent.

If the oil tank is mounted within the field of vision, the oil level is always visible through the transparent tank casing. It’s very easy to fill up the tank through one of the adjustable filling nozzles.

Using oil instead of chain spry means that less dirt particles remain on the chain. The chain remains cleaner, is easier to clean there’s less friction loss in the motorcycle’s drivetrain. This considerably lengthens the chain’s lifespan.

FAQ


General

Are there test reports? What is your experience until now?

  • Since the spring of 2017, the MOFESSOR is on the market and has already been coming into use across the most diverse range of motorcycles. During our testing, we carried out an endurance test without problems. External reviews can be found here: ttmotorbikeblog.wordpress.com and motorradreisefuehrer.de.

Is the system waterproof?

  • Our system is designed for motorcycles which are exposed to environmental factors. We bore this in mind during development.
    The rain switch is certified in accordance with IP67. The control unit panel casing is watertight and secure against vibrations.  The metering valve as well as the rain switch are equipped with a waterproof plug connection. However, the system is not suitable for diving. The MOFESSOR was tested on design-appropriate moving motorcycles. These were exposed to high levels of dirt and water.

Installation/ Compatibility

Which motorcycles does the chain oiler suit?

  • The chain oiler MOFESSOR was developed with the basic aim of being compatible with all chain-driven motorcycles. Many typical assembly situations are taken into account so as to make installation as simple as possible. However, each vehicle has its own shape. This means that individuals have to choose the installation site and connectivity. If there are questions in advance or during installation we are happy to offer advice.

Are there model-specific installation instructions?

  • The selection of model-specific installation instructions are continually expanded and updated on our site. You are welcome to contribute to this and help us by sharing your installation instructions.

Do I need a model-specific connector?

  • If your motorcycle has a special switched connector (auxiliary/secondary consumer connection), then the MOFESSOR can be comfortably connected with a model-specific connector. If this is not the case, the connection is also possible without a model-specific connector. For the connection you can use e.g. the horn or the tail light.

Electric

What voltage/current does the chain oiler require?

  • As standard, the MOFESSOR operates with a voltage of 12V. The necessary current has two parts:
    • The switching current which the chain sprayer activates via the ignition of the motorcycle, adds up to 20mA (0.02A).
    • The supply current which is directly fed from the battery amounts to 500 mA (0.5A).

How can the chain oil be electrically connected to my motorcycle?

  • The MOFESSOR is connected to the battery and to a 12V line which is connected with the ignition. We offer various model-specific connectors to connect the switched 12V line. Alternatively, the connection can take place with every switched 12V line on the vehicle. The connection with the horn is very simple with the help of the built-in branch connector on many vehicles.

Are there any problems (expected) with the CAN-BUS system or the LED light on my motorcycle?

  • No – the design of the MOFESSOR is developed so the wiring system/electrical system/vehicle power of the motorcycle isn’t affected. Until this day there is no known case to us where a malfunction with the CAN-BUS system has occurred.

Oil application / oil tank / oil

Where should the application nozzle be put, on the pinion or the chain ring?

  • The application nozzle can be placed on the pinion or on the chain as desired. Both variants have been tested successfully. Experience has shown the oil usage of the large sprocket is lower and that this makes most effectively use of oil.  However, the best installation point for the application nozzle is dependent on the motorcycle. It should always be chosen with safe application in mind.

Does the long-distance tank go with my motorcycle, what are the measurements/ dimensions of the oil tank?

  • Range: ~ 5000 KM (Standard) / ~ 10.000 KM (Long distance)

In which case should the optionally available, variable tank ventilation be used?

  • If the oil tank is installed with a very slight incline or diagonally to travel direction, it can happen with a completely full oil tank that a small amount of oil leaks from the ventilation opening. The variable tank ventilation is designed to prevent this. Furthermore we recommend to use the variable tank ventilation when you drive off-road, or if you like to drive the rear wheel for a longer time, and if the vehicle is lying on its side for a longer period of time..

How do I find the correct setting for the chain lubrication after the installation?

  • We recommend you to start with level 1 to prevent that too much oil gets on the chain. After approx. 50 KM the setting of the oil charge can be progressively increased. Changes need approx. 200 KM until it can be clearly recognised. The oil charge has to be increased so long as a good lubrication of the chain is reached.

How do I know if my chain is well lubricated?

  • Basically only the chain rollers have to be lubricated (gray) because it is where friction is predominantly formed. The chain sidebar (gold) doesn’t need lubrication:

  • There should be a thin and closed lubrication oil film. It is usually slightly gray and it can be best recognised by touching the chain roller with your finger.
  • Tearing off the lubrication oil film on the chain rollers ( dark spots will appear and then the chain becomes metallic shiny) means that the lubrication setting is too low.

Is the chain lubrication system going to soil my motorcycle with oil?

  • If the chain lubrication system is correctly installed and adjusted the soil on your motorcycle will definitely be less than while using a conventional chain spray. A light oil mist which is deposited on the rim after a long period of use, is very easy to wipe off with the brake dust and the dirt on the road.

My motorcycle is soiled with oil after the installation of a chain lubrication system. What to do?

  • Occasional small splashes of oil and a light oil mist on the rim are normal. If your motorcycle is considerably soiled, the following causes can be responsible:
    • The dosage is set too high
    • The nozzle is not correctly installed, the oil does not get on the chain
    • The chain was not properly cleaned or manually pre-lubricated (even with new chains)
    • The application nozzle was considerably shortened or the wrong nozzle was being used
    • Wrong oil was used

Can I use other oils?

  • We recommend you to use the oil that BEROTEC has provided and tested for the MOFESSOR. Basically, is the use of other oils possible. However so-called “organic oils” as well as sunflower oil and rapeseed oil should be avoided. These oils tend much more to resinify and to clog the system, especially if they are not used for a long time. Substances containing solvents must not be filled into the system.

Is it possible to use a Dual-Nozzle / Dual-Injektor?

  • Regarding creeping capabilities of the oil, the one-sided oil application is enough to cover the whole surface of the chain roll. A Dual-Nozzle that splits the tube has the disadvantage of possible oil dripping after stopping. If the two ends of the nozzles are not in the exact same vertical heights, there is the chance that air is sneaking into the system. The technical correct solution would be the use of two dispensing units and two separate oil tubes.
    A Dual-Nozzle is harder to fit on the bike and often more exposed to mechanical damage. The one-sided oil application / Single-Nozzle has the disadvantage, that on regular rain rides there might emerge surface rust on the outer plates of the opposite side of the Single-Nozzle. To avoid this optical issue you can “over oil” the chain from time to time or you can use a piece of oil wet cloth to rub off the chain.
    You can use a Dual-Nozzle with the MOFESSOR but we do not offer it to sell.
