BL 1000 – indicator and
  damping weight

Technical Information


bl_u_verp.jpg (8616 bytes)

In the BL 1000 the functions of both, an indicator and a vibration damping weight, 
are combined. Its harmonic form and the high quality materials used, for example stainless steel, make it an exclusive product. In addition, the enclosed adapters allow a secure fitting on practically all motorcycle-types. An extensive spare parts program ensures a long-term practical value.
The following models are available:
Execution: Euro/Unit.
Stainless steel, polished 124.800 84,90
Chrome, high gloss finished 124.100 82,90
Stainless steel, smi gloss-ground 124.010 76,90
Brass, blck 124.700 69,90
Brass, chrome-semi gloss 124.400 82,90
Alu-Sport, polished 124.300 64,90
Alu-Sport, black 124.600 59,90

Am I able to just remove the rear indicators after I have mounted the “BL 1000” turn signals?

Do the “BL 1000” turn signals fit my motorcycle handlebars?

Am I able to just remove the rear indicators after I have mounted the “BL 1000” turn signals?

No. The BL 1000 is ECE-type approved as a front indicator. This means they replace the front, but not the rear indicators. The rear indicators, however, can be removed if the BL 1000 indicators have been demonstrated to and approved by a responsible TÜV-centre (Technical Inspection Authority/ Technical Supervisory Association) and if an entry in the motorcycle documents has been made, declaring that the rear indicators are allowed to be removed and that the BL 1000 indicators are the only turn signals. 

The TÜV inspector is granted discretionary authority. This means, he/ she does not have to approve of the removal of the rear indicators. There is no 100% guarantee that the TÜV inspector will extend his/ her discretion to the point of allowing the removal of the rear turn signals. However, you can facilitate the inspector’s decision, for example, by fixing a relatively straight and especially broad handlebar (about 70cm and more) on to your motorcycle. This helps, as the most important requirement during inspection is, that the right or left indicator can be seen up to a certain angle from the other side of the motorcycle. This is a safety precaution, as the following traffic needs to able to anticipate if you want to make a turn. 

Individual TÜV-centres and their inspectors do not use their discretionary authority uniformly. Therefore, if one TÜV-centre does not allow the removal of the rear indicators, another one might. The effort to make enquiries at the centres beforehand often pays off. Further information on the subject might be available through posted messages in our online guest book ( Visitors on our website often post messages with useful information on various subjects, including the occasional note on which TÜV-centre has previously allowed the removal of rear indicators in combination with our BL 1000 turn signals. Due to organisational reasons, we are not able to check and verify all entries in our guestbook. Therefore, it is advisable to call and check the situation first, before making long trips to various TÜV-centres. 

Attention: without TÜV approval and entry into the motorcycle documents, rear indicators may not be removed. This leads to loss of the operating license and insurance protection. 

Do the “BL 1000” turn signals fit my motorcycle handlebars?

The BL 1000 turn signals are standard equipped with three different adapter sets, which enable a fixation to all current motorcycle tube handlebars with an inner diameter between 12 and 24mm. Always use the adapter set which includes a rubber that just about fits into the handlebar tube. This way the rubber hast the largest possible contact surface with the inner tube. Installation is very easy and thoroughly described in the mounting instructions. They also include various tips and answers concerning different smaller problems that might occur during installation.

Which preparations do I have to make so that I can mount the “BL 1000” turn signals on my handlebars?

If your motorcycle is equipped with a standard tube handle bar, preparations are limited to either one (4mm) or two (each 3mm) drill holes for the electric cables or two drill holes (each 4mm) for the electric and earth cables. These drill holes should be located in between the clamping blocks of the handle bar. The installation requires a smooth inner tube with a consistent inner diameter. Therefore, welded nuts used for the fixation of vibration damping weights or something similar, need to be removed without damaging (for example by drilling them out) the handlebar as such. Always pay attention not to damage the actual handle bar tube, so that the stability of the handle bar is not affected. A damaged handle bar under strain (for example by applying the brakes or braking hard) may crack or in the extreme even break, which usually leads to a fall. Should a removal of welded nuts or screws not be possible without damaging the handle bar tube, then this handle bar needs to be exchanged for a different one which is suitable for installation.

Attention: a certain degree of experience and mechanical skill is required in order to carry out these preparation measurements for installation. If you are not 100% sure, you should let a professional garage make these adaptations.

Which models are available and which aspects should I take into consideration when choosing?

Ten different versions of the BL 1000 indicator are available. The design and the technical equipment – meaning the different enclosed adapter sets and the halogen light- are always the same. The versions differ in the material used (aluminium, brass, stainless steel), the mode and the intensity of the surface processing (polished, satin honed) and the type of coating (black powder coating, chromed). 

The different versions can be roughly separated into two categories:

Vibration dampers:
BL 1000 polished stainless steel
BL 1000 satin-honed stainless steel
BL 1000 high-gloss chrome
BL 1000 satin chrome
BL 1000 polished brass
BL 1000 black powder coated brass

No vibration dampers/ light weight:
BL 1000 satin-honed aluminium
BL 1000 polished aluminium
BL 1000 satin-chrome aluminium
BL 1000 black powder coated aluminium

The first question you should ask yourself is, if you can do without the vibration damping function. An apparent indication that vibration damping is necessary is either if the original handle bar already has vibration damping weights or if numbness in the hands occurs after lengthy journeys. You are always on the safe side if you choose the vibration dampers. 

The second question is: which of the above mentioned versions should I choose? In general, we do not recommend combining two different materials, for example aluminium handle bar ends and chrome BL 1000 indicators or chromed handlebars and aluminium BL 1000 indicators. Due to different materials, the versions differ in colour and appearance. It is very difficult to describe the different brilliance nuances and shades and almost always fails.

1. Attempt: stainless steel polished has a deeper dark brilliance, chrome has a deeper bright brilliance and aluminium polished has a more superficial bright brilliance.
2. Attempt: stainless steel polished has a warm brilliance, chrome has a cold and more sterile brilliance and aluminium is somewhere in between.
3. Attempt: no clue whatsoever on how to describe the differences!
Only one thing is for sure: it somehow just does not look right to place different materials next to each other; they stand out. It simply isn’t perfect!
