Since the bike is basically just a shell of what it was six months ago there are no real plans to modify over the winter, except for a) new seat and b) new rear turn signals. Those two things are basically the only original parts left.
It has brand new oil, coolant, and tires now. It does need a brake service but I will do that at the start of next season. I'm hoping I can stumble across a decently priced set of Brembos over the winter but it's not a "need" by any means.
