Just to add a little update to this resurrected thread: My
New Highlander Handlebar Conversion Kit is now offered in your choice of chrome or black 8" rise handlebars. Control cables (as mentioned earlier) are Norman Hyde sourced Triumph cables in OE black. I still offer custom stainless steel braided control cables as an upgrade. A new braided brake hose is also included in the kit.
There is enough slack in the handlebar wire harnesses if you pull the connectors out of the back of the headlight shell. Be sure to wrap them with electric tape.
Its nearly impossible to predict how the change in bars will affect how you feel. Everyone is so different. You will not be bent forward as much and you most likely will find the bike easier to steer & handle, especially at lower speeds. As long as your wrists are not higher than your shoulders, you should not have any problem with numbness or blood flow. Also, having your wrists turned closer to a 45° is far more ergonomically correct. Remember that you can always rotate the taller bars back closer to you for less reach & height.
As for the newer 2009+ models, I do not have a suitable set of 7/8" handlebars, but I do have all the other parts: cables & brake hose. For the 2009-2015/16 carryover models with 1" handlebars, the same kit for the carb bikes works. As for the new 2016+ water-cooled models, they have the hand grip wires running through the handlebars, and then there is that fly-by-wire throttle. Those two issues, especially the latter make it very difficult for the aftermarket to adapt. Of course, the factory has a solution for lord-knows how much $$$.
