What is some input on putting a set of clip ons on my CB919f? I've got a vision and a grand idea I just don't know if it's practical.... Any ideas?
If you go with true clip ons, unless you have them positioned so that the handles are set parallel with each other and in line as eyed across the fork tubes, I think they will hit the gas tank at or before full lock.
Such a handle orientation would be awful to ride with, and surely defeat your intended purpose.
I suggest you consider a set of Tharbars.
From WT'er Rob Tharlson.
Their versatility includes a clip on like orientation, and allows full steering sweep without corrupted hand positioning.
If you still want to try clip ons, with your stock tank, I'd suggest trying to jury rig something representative to see how real ones would fit up.
For example, a mock up using wood doweling for the handles.
If it looks a go at least worth trying, then move to buying a proper set of clips ons.
As for the stock OEM triple clamp, because the bar mount towers are hollow, they can't be machined off to make a flat top triple.
One could make an aluminum plate to cover the two saddles, and bolt it in place.
One could have a flat top upper triple custom machined, and that would be the ideal solution.
Top triples from other bikes will surely have a different set back dimension re stem centre to the fork tube holes line, let alone the fork tube diameter they may have.
The upper and lower triples need to have a common set back.
Changing set back affects trail.
Changing set back affects front tire loading.
Changing set back affects location of the Centre of Gravity.
Personally, I've been wondering if a set of F4i triples would fit the 919, noting they use the same bearings and fork tube diameter.
(My interest is in the increased trail the F4i set would provide.)
