Probably cuz everyone was complaining about the suspention on the 09 and 10 touring bikes............how's yours ride? I have a 09 Roadglide CVO and while the bike handles great, it's a back burner when ya hit a whoopee too hard.So as I was reading my new owners manual (slow day uncharacteristically) I was surprised to read that my new bike has pre load adjustment rather than the air shocks on the 09 SG. Why the change?????
