If you're a bit short on green for the high-end flexing levers, such as those from ASV or you don't want to run metal wrap around handguards, a buck or two on Teflon tape (found at just about any home improvement store) can really help to reduce broken levers.
Wrap a few courses of Teflon Tape under both your clutch and front brake perches. When you reinstall the perches, tighten them down just enough to be secure, but not too tight, as the goal is for the perch to rotate on the bars, should it take a good hit. I've used technique this for years and it does work.
As a side note, when you buy standard replacement levers, stick with forged, not cast aluminum. Cast levers snap when hit while forged levers will bend, allowing you to straighten the lever for reuse. Forged levers aren't much more money and they are definately more durable.
Also, about 1" in from the outside tip of your levers, if there is not from the factory, drill a hole about a 1/16" deep (small drill bit) or create a notch about the same depth with a dremel type tool. Why? This creates a spot where if the lever is hit hard enough, it will snap at that point, leaving you plenty of lever left to operate your controls.
Of course you could just avoid crashing all to together, but what fun would that be?
