Exactly why to use the Trick kit. It is just a few wires to connect that come with factory type connections. The entire mask/headlight/controller/front turn signals come off with one electrical connector. Edit - two connectors, power and rear lights and the handlebar switch has its own connector. I upgraded the entire electrical system on my KTM at the same time so it is much more robust than stock. You don't have to. I wanted a headlight that would allow me to see well enough to ride hardtop at night if I need to, a fan kit to keep the bike cooler, and charge the battery at the same time. I still have enough capacity to run heated grips if I want. If you just want plates on your bike, I'm sure you know how easy that is. It just depends on your goal.
