I assume the canbus system is alive and well on the newest C650GTs. I don't get my scooter till this Friday so I don't have a rider's manual yet. Is there a port on the scooter for hooking up a canbus-compliant battery tender? Is the battery hard to get to? Because I may want to bypass the canbus system and attach a regular pigtail directly to the battery terminals. I did this with my 2018 R9T so that I can use any run-of-the-mill battery tender.
