Wow this could get interesting. Time to make a big batch of pop corn.
The Stryker has a unique look , Fist in the wind, I wouldn't screw that up. The height of the bars/grips are already at about 18" from the seat height, not sure if that's where they measure from to call it 18" apes though. And if you want my opinion apes would take away from the Strykers newer stream line bad a$$ muscular sophisticated awesome style by putting apes on it. Besides they got there name,(APE HANGERS) for a reason and I suspect it wasn't because they made you or your bike look sophisticated.

Just my opinion.
