Check the suzuki site or a dealers parts book. Head stock of trees will have bearing numbers- good chance that neck and bearing interchange, should be tapered rollers , close to same neck length. Tubes may be different - 15 years difference in making forks, subcontractor and newer may be air filled. 36mm to 45mm tube diameters , price change for quantity of different pattern for different model more than 10 years could happen. tape measure and calipers if nothing else. I have Yamha tubes in Honda trees on little CM400, same subcontractor, fits good. 450 Honda front to Harley necked trike needed roller bearing kit and a shim. BSA front on Indian frame- ball thrust bearing from bearing catalog made it work. Check Suzi site- might get actual swap info.
