I do not define hard ride as fast for me it is more of the push.
By that I mean on the right road 40 can be fast were on another road 100 maybe no big deal.
Hard ride for me is how active you have to be in controling and making the bike do what you want, How many shifts up and down in a short time the sparks from boards.
If your arms get tired of hold the line thats a hard ride no madder haow fast of slow it may be.
If you have to change you pants when you get back thats a hard ride.
Anyone can go fast.
Well said Smitty and your right Skyline drive and the Blueridge Parkway in a day and a half was one of the hardest rides I have ever done. Should have left at least three days to enjoy it properly and not tire out considering we were two up and loaded with gear for a ten day trip.
