So I've still got to get my learner's. But I really want to invest in some crash protection for my new bike, suzuki inazuma gw250. I've heard of some stuff, like crash bars, frame sliders, knobs... But which is the best protection for the bike if I drop it? Like, which will result in the least amount of scratch damage to the overall bike? And which of these crash protectors are useless? I've seen some people review some of the knob-like products as useless. :-S Also, if you could mention the well know and well reputable brands please. Thanks in advance.
