What is the consensus?
1. Off the road?
2. Metal mule?
3. Yamaha own brand?
4. SW Motech?
5. A.N. Other?
Bearing in mind that I am probably going for the Adventure spec bash plate/engine bars combo, are any of these incompatible?

My other bike is an Aprilia Pegaso Trail, a bike nobody makes anything for. You are lucky to get a choice of one. Yam XT660Z has an embarrasment of riches when it comes to aftermarket part choices. Help!
