I extracted this information from Marty and Charlie Mullendore of Antietam Classic Cycle on the Yahoo! Loopframe_Guzzi news group.
I called Bob's BMW last Saturday morning and ordered-up the BMW fork lock, and it is the same Niemann part, complete with a pair of keys. There are 2 small differences to the Guzzi part; 1) the Guzzi part has a spring around the lock pin, which the new part doesn't, so just swap it over, and 2) the Guzzi lock is ground flat on both sides of the business end of the pin so the end of the pin is about 7 mm wide, but the BMW part is a straight cylinder. I realize now that this relief is so the pin can engage the keyway that's ground in the steering tube, doing the locking, so there's a little grinding to do.
BMW part numbers and prices are as follows (Marty ordered these parts from Bob's BMW; Bench Mark Works also sells them):
- Lock and 2 keys: p/n 51 25 1 243 274
- Fork cover rivet: p/n 07 11 9 944 651
- Spring washer for the rivet: p/n 07 11 9 932 100
- Chrome cover with rivet and washer: p/n 32 32 9 016 101
