Well, they wil fit. Since they were a universal aftermarket accessory-they will sureley fit almost any bike-and be usable on about any bike with the appropriate wheel travel design. The stem may or may not be the one you need, I would expect that one can be machined for less than sourcing one specific for you make and model. Also, you will likely need to fabricate a brake stay/and or cable guide depending uopn your setup. Of course, should the forks have been previuosly fitted to an era 81450,82-83 480, or 84 500 -I expect you may have the correct parts already.
