My Speedy came with the 16T front sprocket so it's geared very low.
6k rpm is right about 100mph, and it will motor happily along at this
speed for as long as you care to.
I'm 6' and 220 so weight is not a problem.
As far as vibration, the mirrors on this bike are the most
blur-free of anything I've ever ridden.
Getcha one! You'll never regret it.
