Subframe, airbox, seat, rear plastic, and a few other odds and ends.
Do a search, Berkyboy from GoFasters did a post on it a few months ago, with prices.
Not sure I want a wider seat, a shade softer maybe but not wider. Husky did this too, I like the narrow seats on them better.
Battery less injection is a good deal, as now you have the option to drop more weight by dropping the heavy battery and kicking (if they fixed that), or going to a lightweight NiMH or LiOn pack. Wonder how an EFI 4-stroke kick starts if the starter gear train is right? Looks good, now we need an FSR320!
