HONDA CB175 front brake and hub is a good-un. Whole wheel or laced into MZ rim. CB250 would be good too. Back in the 80’s I did this and changed the front brake lever to Honda at the same time which with the left hand matching switch gave me much easier to use switches at the same time. GYR 704W it was. Gave it to a work mate and I believe it is now used in MZ Racing.
