Coolant reservoir for BMW K100 and K1100.
Completely made in stainless steel and welded and then powder-coated in RAL9005.

These mount on the front frame tube on the right side where originally the support of the fairing is bolted. For models that had no fairing fitted at factory the version for the K75 can also be used.
Bolts for mounting are included, as is a connecting hose between the tank and the radiator cap.

The tank has a maximum capacity of 280ml but should only be filled halfway. Thanks to the transparent connecting hose, you can check the contents of the tank.

The overflow on top you can mount the original hose and let it run to the bottom of the block.
