Respecting the opinion, thoughtfully formed and offered in good faith, but . . . so the rider will drop the bike. So what???????
The Generation 2 KLR650 will profit from crash bars (nerfs), protecting plastic, tank, and radiator, but . . . what's a few scratches/cracks/etc.? Basically, they add character to the machine, one might say.
And . . . dropping bikes is part of motorcycling, at least it has been, and is still today, after many, many decades of riding in my own experience.
So, I'd say . . . get that 2015 KLR650 (if you're going to keep it a while, the condition will be more important in determining resale than the $ 1000 model year premium). That first scratch may be painful, but . . . will witness some learning and skill development.
Dirt bikes and dual-sport bikes WILL get dropped; get in the game and deal with it.
Welcome, and best wishes with your new bike!
Again, respect the contrary opinion offered in good faith and to the purpose of your best interest, but . . . I disagree!
