We replaced the stock fixed mirrors with new Double Take mirrors on pivots-- if you drop the bike, it bends and you can replace it with other accessories like a coffee cup holder (not a joke). They are also completely adjustable.
Although my boyfriend is a big fan of having only one side mirror on the right hand side, I kept the dual-mirror set-up with a mirror on each side, for safety reasons.
We also installed heated grips on both sides.
Old "stock" Kawasaki fixed mirror-- not very crash worthy
With the moveable mirror, you can pivot it away from other bikes when trailering side by side
Heated grips on-switch. Ahhhhhh... so nice on cold days.
