I did the same calculation for the exhausts last weekend.
Each original are 4.8 kgs. An Akra aluminium is 2.2 kg. If you from stock to a two in one Akra you go from 9.6 to 2.2 kg! Saving 7.4 kgs placed in a high position. There mght be an other little bit saved using the 2 in 1 connection.
Also the two passangers foot pegs are 1kg together.
Passenger arms holder are another 1 kg together.
So if you do a rough calculation you'll see that:
- 2 in 1 +
- Front single brake +
- Remove foot and holder for passanger +
- Light battery
You save some 15kg from stock that match a SE if you start from a 950 Adventure. These are not expensive mods.
You can probably save more with lighter rims.
I guess if these mods are joint by good suspension setting it should improve by far performance off road
