If thats your bike, I am guessing it already has the basic mods. Exhaust, programmer, intake. Those are the first main three that wake up a 700. Before you extend everything, you might want to figure out what type of riding you are going to do. Just modding something without a goal makes no sense. Longer swingarm is for keeping the front down for straight line drags or racing. If you ride tight trails that would be a bad idea. Wider is usually for sand, where width does not matter but any extra stability is welcome. If you ride trails, how wide are they? If you are only on road, I really cant help there, in the USA most places you cant ride on the road legally.
