    Description


    Wunderlich Hydraulic Line Extension

    When converting the standard handlebar to a higher accessory handlebar or when installing a handlebar riser, it may be necessary to adjust the length of the standard hydraulic lines for the brake and clutch, i.e. to lengthen them.

    Our high-quality adapter for the brake and clutch lines extends them by around 35 mm, a dimension that has proven itself in practice. We add the necessary banjo bolt and all the necessary seals to the practical adapter. It is installed directly on the respective brake pump or clutch fitting. We have angled the adapter moderately, this makes it easier to connect the supply lines, which can be routed and connected stress-free in this way.

    Using the adapter saves the cost and hassle of making and installing new (approved) hydraulic lines.

    Note on installation and your safety: Specialist knowledge is required to attach the adapter. For this reason, assembly and commissioning may only be carried out by specialist personnel or a specialist workshop.

    Great quality
    | April 13th, 2026
    After installing bar risers on my R1250RS the clutch line was a little short. I first bought one of the cheap imitations of this and it would not stop leaking, so I then purchased this one and the problem was solved. It truly is great quality, It deserves five stars, but I feel the cost is just a little high.

    Precision machined pieces
    | January 18th, 2026
    After installing Heli-bars on my R1250 RT, I wanted a little extra slack for the hydraulic and control lines. Armed with the knowledge from the previous reviewer, I installed the hydraulic extensions. These extensions were crucial in eliminating any strain on the lines after the Heli-bar installation. Follow the torque values specified in the visual instructions and you should be good. I’ve had no leaks, but I did reverse bleed the front brakes to insure that there was no air in the lines. The are well made pieces.

    Useful, nicely machined product. BAD instructions.
    (Atlanta, GA) | July 1st, 2025
    After installing the Wunderlich "GS" style handlebar kit, I wanted a little more slack in the clutch line. This fitting did the job. Despite the confusing instructions, it only took about 20 minutes to install. I did not have to bleed the clutch line. After installing the fitting I pumped the clutch lever about 30 times until I felt some resistance. It's as simple as that. Now, as for what's wrong with the instructions... the fitting comes with two copper crush washers and two composite washers for the banjo bolts. The instructions seem to show both kinds of washers going in the same place. I was very confused until it dawned on me to look up the translation of "bremsarmatur" (brake fitting) and "Kupplungs-armatur" (clutch fitting.) Duh! Now it makes sense... the copper washers are for the brake fitting and the composite washers are for the clutch fitting. This is a nicely machined piece, albeit expensive. I gave four stars because of the confusing instructions otherwise it's a five.
