Have heli's - with a throttle meister, and the heavy
ends weights and this seems to have less vibes than
I also have a set of Johar Superbike Foam Grips
These are pretty big around, but you can sand
the foam to your size, or if you have heated grips,
can sand the throttle side to the same size as the
clutch side grip.
No issues with hitting anything at lock, and only
thing is the heli bars are wider than stock, and
seems like you have less room for the lever pedestals,
switch brackets, etc - so found that placing everything
on the bars was a bit of a pain...
I have my throttle cables flipped over though, as the
stockers would not reach cleanly.
