Sure you can make the front fit but I don't think you can fit it on the rear unless you got thin tires, I'll look tonight, but theres not a lot of forward clearance in that swingarm if i'm remembering right. maybe with one of the robot extended swingarms
Just about any 17 should work up front, you just might have to modify it to fit the brake stay and you'll have to ditch or mod the fender
on the rear if 17'll even fit you just gotta make sure that it's oneside drive and opposite side brake. Puch won't work cuz they got a separate pedal chain but I believe Sachs, Derbi and most Italian wheels use one-side drive otherside brake.
The only issue then is getting small enough rear sprockets, for sachs the smallest are like 36, which even with the larger wheel won't give you much topend.
