Hand guards just used to be one piece of plastic that bolted on the brake & clutch bolt. Now they are broken up into Hardware fitting kit, which comes with a small weight that fits between the grip metal bar, then choose the plastic guard. Then you can have the 'additional' bar end weights on the outside.for another AU$50. They don't look much but do have a bit of weight to them, I found there was no more vibration at the grips than with the original bar end weights.
You can if you wish add 'Skid plates' to the outer edges, a bit more protection for the already installed protectors.
