Basically, what Gulgo said. In thousands of miles of trail and rally miles, and a lot of 'horizontal time', I've broken/damaged:
- A couple of handguards.
- A couple of indicators.
- A couple of numberplates.
- A screen, when I dropped the bike off the back of the pickup.
- Slightly bent the rear brake lever a few times.
- Bars aren't quite straight, but close enough that I can't be bothered to replace them.
Before you do anything, buy proper ally-spined handguards. I use Barkbuster Storms, because they combine decent weather and crash protection. I've twice crashed hard enough to bend the ally spine itself (as well as countless minor offs), but I've never broken a lever. Guys I ride with who use the silly KTM style plastic ones seem to end up changing levers every time they fall off.
I've got the Yamaha ally bashplate and engine bars on mine. I'd say the bashplate is worth having - mine has the scrapes in the bottom from grounding out over rock-steps. Not so sure on the engine bars - I've got hung up on them a few times in deep ruts and had to lift the bike out. But on the other hand if you had a fast get-off on tarmac they would keep the engine cases off the floor.
Otherwise, get out there and ride it. While the grey plastic bits might be called "air scoops" by Yamaha, they're really "crash panels", and they will take a lot of abuse (and they're cheaply replaced).
If your bike is shiny at the moment, I'd consider putting some clear film on the tank where your knees rub - dirt on your riding gear will scratch it up nicely. Bit too late for mine
