One way to reduce the clutch pull effort is to use a lighter clutch spring in combination with something like a VPC pressure plate. The VPC (variable pressure clutch) uses centrifugal force to apply more pressure to the clutch plates as rpm's increase. This will result in a lighter effort clutch pull at idle and low speeds, but that effort will increase as rpm's increase. Assuming she doesn't do a lot of 6000 rpm shifting, that shouldn't be an issue. There are many combinations of VPC and spring to suit different purposes. If the bike is basically stock then the VP68LT model of the AIM VPC is designed to reduce clutch pull effort approximately 40% and still provide the clamping force to prevent clutch slip. There are other models for people with modified engines to suit the torque output of those engines.
