When I drive narrow, twisty roads with large lean angles (> 42°) and many following curves, I noticed that the necessary steering forces are sometimes quite high. Especially the shifting from one leaning angle to the other is sometimes difficult. I have thought about this at home and have put up the following theory. I would like to introduce them to you and ask for your opinions and experiences.
I've been riding motorcycles since I was 16. After all, that's already 21 years.
Just to start with, so you don't think I'm a beginner who just needs to practice a little more. You can never have enough practice, but my feeling tells me that something is going on here.
Our cockpits looks like that:
I would like to draw your attention to the following:
- The handlebars are not mounted as clamps around the fork tubes, but are screwed onto the fork bridge.
- The angle is similar to that of super sporty bikes like the V4S.
Cockpit from the Z1000 SX (Many say that it is the main competitor of our motorcycle):
As you can see, the handlebars are mounted directly to the fork tubes. In addition the angle is much wider, so that the handlebars are much wider. Therefore you can realize much higher leverage forces. The leverage becomes larger by the wider handlebar and at the same time the force is transferred more directly by the mounting on the fork tubes.
Cockpit from the Honda CBR 650 R (in my opinion, biggest competitor):
The handlebars are mounted at about the same angle as on our motorcycle, but just like on the Z1000SX directly on the fork tubes.
The handlebar of Supersport has two disadvantages:
1. mounting from above on the fork bridge, so that forces are transmitted only indirectly
2. the angle is similar to sporty motorcycles and less suitable for touring
Overall, this results in much higher steering impulses, which the driver must carry out in order to move the machine from one leaning position to the other.
What do you think about it?
Is it a solution to mount the Ducabike handlebar stubs? What experience have you had with it? Would you recommend the 2° or the 10° version?
