Folks,
Need your input. Well, last fall I laid the bike down in traffic. I was extremely lucky and got by with only minor injuries and the bike amazingly will be pretty cheap to fix considering the fact that it slid down the road. I firmly believe that if the bike fit me better, I may have been able to avoid the accident altogether. I am 5'8 and have a very short inseam. I have noticed that when I go for the thin and tiny rear brake that comes stock on our bikes, I will sometime miss it or am not able to apply an appropriate smooth amount of pressure.(wide tank I presume.....when sitting on the feminine accomodating Sportster, I have little trouble reaching the brake)What are my options on making this bike fit me?

I have bought floorboards from another member of this site as well as a used rocker shifter. Are there any larger aftermarket rear brake pedals that provide a larger surface? Is is possible to bring the brake closer to the rider? I am also thinking about bringing the bike to a small mom and pop bike shop and asking them to help "fit" the bike to me. The bottom line is that although I am somewhat gunshy about getting back on the ride, I will figure out how to become good at riding a bike. I did not break my hand for nothing. Would appreciate your input.
Thanks,
Jason
