Steering Research: Static Tests #2

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

In light of the new steering setup (handlebars and drag link), I needed to retest some of the geometry combinations under static conditions. I only tested the 20º/30º/40º combinations because those are the ones which are most likely to be used in real-world conditions. Testing began at 10:46 am and the temperature inside the garage was 78º.

Unlike previous static tests, the wheel was only rotated 15º, which was the largest turn I saw during the low-speed kinetic tests. Each combination was tested twice and the results were averaged. The point on the handlebars where the scale was connected was 12" from the center of the rotation.

Static Tests #2 Test Notes

(1) Did not show a tendency to fall into turns as much as #8

(2) Wants to fall into turn after 6-8º

(3) Wants to fall dramatically into turn after 20-25º

(4) Effort is only required for first 3-5º, then falls rapidly after 30º

(5) Same steady effort from 0-45º, no change high or low

(6) After 15º, only 4.5 lbs effort all the way to 45º

(7) Falls sharply after 15º, and wipeout past 30º

(8) Only 3.5 lbs effort after 30º and thru to 45º

(9) Only 3.0 lbs effort after 15º and thru to 45º
