It is questionable as to whether or not the results from SAE J1168 are even applicable on vehicles with a tilt sensor installed to disable the ignition and/or cut off fuel. I am looking at SAE J1168 REAF. JAN2007 which references to SAE J213. Everything is related to bank angle which is pointless when/if the tilt sensor is configured to disable a bike at anything less than maximum bank angle.
Basically it doesn't matter how far you can lean your bike, it is only going to lean to a specific (untested by SAE J1168 or SAE J213) angle before the engine cuts off and you get to find out how well your highway bars are designed.
If you really want to know how far a bike could potentailly lean the optional method of testing per SAE J1168 would be simple to do at home:
6.1 In lieu of the measurement procedure specified in Section 4, the following optional measurement procedure
may be used.
6.2 The test motorcycle, prepared in accordance with Section 4, shall be placed on a rigid, tiltable surface as
illustrated in Figure 2. The tiltable surface shall be of sufficient rigidity and size to yield results equivalent to
those obtained in Section 5.
6.3 The tiltable surface shall then be inclined until contact between any component of the test motorcycle and the
tiltable surface can be visibly observed, as illustrated in Figure 3.
6.4 The test motorcycle shall be positively held in place such that the longitudinal plane of symmetry forms a right
angle (90 degrees) with the horizontal.
6.5 The bank angle shall then be determined by measuring the angle between the tiltable surface and the
6.6 Sections 6.3, 6.4, and 6.5 shall be repeated at least 3 times on both RH and LH sides of the motorcycle.
6.7 The bank angle shall be determined by averaging the three lowest values which are within 1 degree of each
other on that side of the test motorcycle that yields the lowest values.
Your "tiltable surface can be something as simple as a straight edge placed to the side of the tread surface of you tires. With the bike standing up on a flat surface place the straight edge as mentioned in the last sentence then raise it up at an angle until it contacts any part of your bike. As mentioned in paragraph the bank angle shall then be determined by measuring the angle between the tiltable surface and the horizontal.
