2018 vs 19 Honda 450

Taller bars slowdown your turn and less responsive .. I had a 17 and now a 19’ and putting in taller bars isn’t necessarily a comfort thing as much as it is a control thing. Try spacers with a good bend.. also moving the bars back on the triple clamps tightens up the turn not to mention a few other things but as apposition to forward from neutral, far forward can have the opposite affect. It’s confusing but’ in short, find a good bend after you made yourself good room first but not by Changing from short or taller bars. I’d stick with risers or possibly trying bar mounts forward but if you’re not tall enough this could slow down responsiveness /arc in turns , making your bike less responsive all around as well.
Hope this helps in any way, good luck. Try it all and see for yourself, it’s the only way to find a better way.

Shift the bars to the forward mounts. Makes a world of a difference. It takes 5 minutes to change. Play with the options they gave you before spending money on bars.
