i have tomos mags on my magnum. my front fork is also from a tomos sprint and that wasnt hard to mount. rear wheel is mounted in a MLM swingarm, custom brake stop (big bolt in a hole i drilled) and the rear sprocket was a giant PITA... tomos dirtbike sprocket trimed down with an angle grinder (was too wide).
the effort was worth it though. brakes are way better and ride height dropped.
