Thanks for welcoming me.
Yes, i believe that the 125 is a bit heavier, but the shock does not carry the engine's weight since the engine is below the shock. if they have the same chassis, most probably they're carrying the same weight. Though of course, i will replace my suspension with those that are designed for monoshock since the stock shocks may be too soft if the other one is removed.
already tried searching thru scribd, didn't find any.
