With some of todays bikes and their plastics, you have to drill to put some sliders on there. Would you buy a bike that had the holes already in the plastics w/ factory sliders installed? For the bikes that do or do not require holes to be drilled. I figure it would be easier and cleaner for the factory to do it. I know i would definately go for it. Would you buy it if it was standard and couln't buy one w/ out?
