So got a wild hair the other day and removed the lowers before a trip to OKC (roughly 90 miles). All I can say is WOW, what a difference. You want to appreciate how much wind your lowers block, take them off. Now don't get me wrong, it wasn't a bad experience! With it being 100 degrees every day, that extra wind was very welcomed. And around town, can't beat it. Didn't take me very long to take them off either, maybe 15 minutes tops. So if you're riding an Ultra, and want to be a little cooler during these hot summer days, I highly recommend popping those lowers off and see what you've been missing!
