I just finished a short long trip this morning. I went from Rockford Il to Crystal Lake Il--for those unfamiliar with the world's great cities, that is a distance of about 45 miles. I made it in 2 hours and 8 mins--according to my Cateye--doing an average of 20 miles per hour. Now, having a motor on a bike is a blessing and a curse. The blessing part is obvious. The curse is the motor allows you to be on the bike much longer and sitting much stiller than on a non powered bike.Also, a motor doesn't make a bike seat into an armchair. So Mr. A$$ can get really sore and cranky. Also your hands can get numb from the vibration of the engine--even though it might be pretty subtle it still can do a job on the nerves. About 3/4ths into my journey I was so stiff and numb I had to stop, kill my perky little honda 4 stroke, get down off my bike and stand there on the shoulder like a stunned steer. If you've every wondered what having rigor mortis feels like I think I can give you a very evocative description of that state--or just sit on a bike seat for almost two hours on a cool morning going 20 miles an hour and you can find out for yourself.Bottom line--make sure you have a BIG soft seat on your machine and wear gloves that might absorb or deaden the vibe. You would be well advised to get off the bike every hour or so and walk for a few mins. Just some things to ponder before you set out.
