Current new Gen II wet weight quoted by Yamaha is 644 lbs. Gen Is were from about 520 to 550 lbs. Heated grips are now standard according to the Yamaha web-site, but were not available on older models and options on some (AE excluded). Top box is not included on the FJR, and the stock box/rack will set you back a purdy penny. Saddle bag liners are included though on the FJR, at least in the US.
