The 79 and up DOHC cb750 & cb900 wheels are a bolt on to the cb650, DOHC cb750's have a five bolt rotor and some models came with spokes. I spent the time cross referencing the hubs, axles, brake discs etc etc trying to find a bolt on option for my wife's cb650c. It came with reverse comstars which are hideous in my eyes, managed to find a donor cb750 roller with decent wire wheels which solved my problem.
