Wanted more airflow because of the heat and removed it last week. It's like riding a different bike. Above 6,000 rpms in 3rd gear the engine spoke to me and said, "I am Gladius more lean angle." It definitely feels more sportbike-like. It's very unusual to see a Wee without a windscreen what are the differences in performance with/without one? Real or imagined it's a lot of fun right now.
