The kid is sprung weight, I was talking about unsprung weight...more akin to using a heavier rim, etc., than cargo, when the drive train is hanging onto/supported by the steering/ hub, etc.



IE: think of it like this - If your wheels weigh about 30-40 lb more each, it increases the forces on the shock that have to damp their motion....

So - A shock valved to control (Let's say a random weight) 60 lbs bouncing up and down (tire bounce, etc..) would be unable to control a load of 200 lb bouncing up and down, it would not be "stiff" enough...

If the load was only one pound bouncing up and down, that same shock would be "too stiff".

Does that make sense yet?



So - It might not be enough of a difference to matter, but if it does, that would be why it might.
