parallelogram lower engine brackets for bidalot RS and MBK with modification.

technology so far beyond my comprehension i don't even know what to say right now except wow!

amazing machine work and specifications here...these will require modification to your frame to fit motobecane as they are originally made for the bidalot RS frame.

You need the other upper bracket here: https://www.treatland.tv/JD-RACING-MBK-parallelogram-upper-engine-brackets-p/jd-racing-parallelogram-par02.htm

You also need to fabricate your own bracket adapted to your engine cases. As there's no rubber bushings on that lower bracket make sure to rubber mount your engine spring as well to adsorb the vibration.

It exist different shim sizes (zip tied spacer on the pic) to properly align your parallelogram which is crucial or you will have belt distortion problems.

Even though this is vintage technology it's a very precise system and your old engine spring tension settings will change.
