And you can easily tell if an item has never been used.
That steering lock sold for $332.00
That's because of the key...not the lock. 754 was a Z1 number. Same thing with the dash panel...it's Z1...74 or 75 only and a very hard item to find. Very nice finishing touches and very visible to anyone who sees the bike.
The clutch on the other hand....there are dozens of them. Any clutch from '73 to '80 will fit. How many people will be asking if the clutch is NOS?
I have a couple of Z1B's restored, an '80 KZ1000LTD restored, a 1981 KZ550 restored and a 2008 KLR 650 for off road fun. My wife has a 2019 Suzuki DR 650 for on and off road.
