If you wanna lighten the bike further try one of the KHE lightweight tyres up back, and their offroad equivalent up front, should offer a significant weight saving, and makes a huge difference to the way the bike handles/can be thrown about.
Then take the front brake set up off, cut the fork steerer tube a little bit, remove a few headtube spacers, that lot combined should save a nice chunk of weight off of the bike without compromising durability.
