My personal recommendation would be to remove that as soon as you are ready to start hitting the streets on a regular basis. They have a nasty tendency to fold up like a bear trap when the bike falls over, and pin your foot just like a bear trap is designed to do.
I can 'second' that one from real life experience. Had crash bars on, took a slow inside left turn fall and truly believe this bar in combination w/steel-toed boots managed to crush my heel good and break all 5 metatarsal necks in my left foot.
Being 400 miles away from home wasn't good either. Ug, bad memories
I have engine guards, but I will never (ever!) put crash bars back on! I would have much rather had more damage to my bike than my foot! Hell, I would have much rather watched the bike slide over a cliff and explode vs. a lightly damaged bike and a busted foot.
They look cool and do protect the bike, but most of the time, the rider pays for it! Have yet to hear a good story about those 'working' for the rider when crashing. They also facilitate the bike sliding further after its on its side than it would without. smooth (weighted) metal is almost frictionless on concrete.
Maybe the guys that can 'lay-down' their bikes like them, but I am always leary of people that think they can control physics implied by this statement, especially at heavy metal at high speeds. I will never understand that. I can tell you when I fell (no 'lay down' crap here-I fell down, a fall is a fall, a crash is a crash.) that crash bar did more for the bike than me.
Careful with those...
