The Speedmaster (which I just sold, long story, but it involves needing cash) has more HP and torque than my Harley's 1450cc engine.
It takes off way faster, doesn't like to cruise as fast (85-95 on the Harley Softail) ONLY because the Harley is heavier and doesn't get blown around as much... I ride solo.
Oh, I was doing a lot of riding in extremely wind, 50 lbs of stuff on the back is not equal to a passenger.
Ok, except out in West Texas, 85 is illegal anyway.
I only took a couple of short trips, maybe 700 miles each round trip, no problem. The bike just hummed along. although I did have to donwshift a time or two to pass...ok, I didn't HAVE to downshift, but hey! How're you going to know what redline sounds like if you never get there? <G>
The America was more comfortable, but I bought the Speedy because at that time (06) it had twin front disks. Most of the stopping power is in the front, the Speedy will stop way faster than the Harley with one disk does. And I like the look of the Speedmaster better.
Plenty guys on this forum ride two up all over the country. No problem. Unless you're 6'5" and you, your passenger and your luggage outweigh the bikes weight limits, you shouldn't have any problem.
Do some kind of AIS removal, makes a huge difference. Plenty of info here.
Take care and ride safe.
