This is a complete turn signal assembly, supplied with the base, housing, reflector and lens. These parts are only available individually from BMW and if you were to each piece, it would add up to more than the price of this entire assembly.
This turn signal is made by CEV, the original equipment manufacturer, so it is identical to the original and not a reproduction.
Please compare the picture to your bike to be sure that you are ordering the correct replacement.
Overall Length from flat of base to tip of turn signal = 11.8cm (4-1.2")
Height of stalk, exposed length installed (not including locating pin)=28mm (1-1/8")**
R1200 GS Owners, please note: The USA versions of the R1200 GS uses a longer stalk than is supplied with this turn signal assembly. If you install a set of these turn signals, the signals will be shorter and closer together, like a European model. This change really looks great and it keeps the turn signals more tucked in and less vulnerable.
If you with to retain the US Specification or of you are only replacing one side, you can re-use your old turn signal stalk if it's not broken.
**Long Version USA stalk is 68mm long. These turn signals are 40mm (1-5/8") shorter than the originals.
