One reason I bought my Classic is to get practice and experience handling a large cruiser at slow speeds, versus my many years experiences on my much lighter easier handling BMWs. Yet, so many of my students ride cruiser style bikes, especially Harleys. This is really evident when I teach slow speeds skills during the Street Skills classes at Road America. My students say I make it look so easy when I demo it on my BMW R1200RT.
Come to find out now, that the same actions on my Classic VN1600 take a bit more skills than I had. So the practice on a much heavier, longer wheelbase Classic opens my eyes about what my students have to do. However, that practice and what is shown on this very good video (not me) proves that with the right skill sets it can be done:
technique to doing most of these actions is confident clutch and throttle action, with rear brake application. Turn the volume up on the video and you can clearly hear the throttle is on and steady through all the actions. The bike HAS to be driven forward with momentum within a foot of rolling to feel confident. Practice smooth consistent clutch/throttle action combined with REAR brake application doing short straight ahead starts/stops. Once that feels consistent, do it again with the handlebar turned. I also practiced the MSF tight turns from a stop at the corners of the range, and found it is easily done with the right combo of controls. Again, practice. In my book, any MSF Rider Coach should be able to do any MSF exercises on any MSF bike, AND their own bike. Doing that proves to the students that the techniques taught do work. I like the picture grab from the video below: good upper body position, great head turn, note the brake light (REAR brake only).
All that said. On my 1st day riding my Classic on back roads south of Jordan MN I had to turn around on a gravel road and I caught myself slightly grabbing the front brake as I did a sloppy Y-Turn. It was, "C'mon Andy, get your crap together, you know how to do this." But the feeling while doing the turn made it very evident how quickly the bike and the weight can get away from the rider in a fraction of a second. Practice, practice, practice.
