(Top) speeds in gears: stock and 15T countershaft spkt.
At the 13K redline with stock tires/gearing in first through sixth the 300 goes: 38 / 58 / 73 / 89 / 102 / 120 m.p.h., so . . not allowing for tire expansion, 100+ in 5th is very attainable. If you HAVE to see "round" numbers, a 15-tooth sprocket yields: 40 - 60 - 75 - 90+ at 13,000 in the first four gears. Fifth gear at 12.5K = 105 mph and, like most six-speed automobiles; shift to sixth and you slow down. This, I know from trying; been there, done all that. Unless you have a tailwind and/or are on a steep downgrade, it takes more power to go any faster. Though these bikes are amazing, "top end" is not my reason for buying one.
