It depends on the crack. I have two cracks in my front fairing, by the headlight (each headlight) and I have a replacement already but it's not bad enough for me to do all the work of unbuttoning the fairings and changing it out.
pic of the crack?
yes, we all have mistakes and drop a bike. I definitely have. I just came back from laguna seca, and I took on a passenger to share the gas bill, but he didn't the canyon dancer before he put it on, and it was leaning pretty badly. luckily ppl behind us, when leaving the track told us, so we stopped and tied the bike down again and caught the mistake.
