Just found a fella in CA with 2 of these bikes, and a bunch of other Suzuki enduro parts. I think I'm getting a complete 98 dr650 rear suspension to replace the steel girder of a swing arm. I should only need to fabricate the upper shock mount. The motor weighs 88lbs, and the rear suspension with the wheel, brake, swing arm, shock, and associated linkage weighs just under 50lbs. The new set up will have a newer rebuildable shock. I'm guessing it will save 6-8 lbs. Still aiming for that 270# mark.
