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). Part numbers:
Lock and 2 keys: 51 25 1 243 274
Fork cover rivet: 07 11 9 944 651
Spring washer for the rivet: 07 11 9 932 100
Chrome cover with rivet and washer: 32 32 9 016 101
Robert F. Greene also sent me a source via e-mail:
Until recently, I did not realize that the fork lock and tool boxes on Eldos were keyed the same. Unfortunately, not only was I lacking an original Neiman key, but the tool box locks were non-original and missing their non-original keys as well. After some poking around, I found a genuine Neiman replacement fork lock WITH correct oval cover, 2 keys and even the rivet for the oval cover. The name of the vendor is Bevel Heaven.
