I bought a set of these from rockymountainatv and I like them. The green matches my bike pretty closely. Other than cutting off the ends of my grips to insert the expanding sleeve, I didn't have to modify anything. I haven't crash tested them, but they seem pretty stout.

 

I ran Tusk with the extra spoiler for a while until another member here offered up some Bark Busters at a great price. They were crash tested many times and performed well. A good product at a great price. Now they're on the KLR.

 

Those look a lot like the Acerbis and the Chinese copies I have on my KLXs. I have tested the Aerbis on the 650, actually bent the left one in a bit on a hard fall to that side when the front wheel washed out in a rut at a fairly high speed for a trail - work fine! Haven't really tested the ones on the 250 and really don't want to, but probably will one of these days.
