I use both th Acerbis Rally Pro and the Maier
I think the Maiers are the Woods XC ones. In any case, they are just the simple aluminum bar. I purchased the plastic that bolts to them separately.
I prefer this to the Acerbis for the following reasons:
1) Easy to bend to fit. You can't put all Rally Pros (or any other plastic hand guard) in a vise easily.
2) Cheap to replace the plastic. I have broken off a good portion of the plastic on the Rally Pros. You need to replace the entire set to fix the plastic. With the Maier's, I cna just order new plastic and bolt it on.
