I've got a gs911 which I use on the 11r and gsa, and can follow realtime readings. I'll take it slowly and will shout HELP very loudly.
I agree about the fuel gauge bit, I'm think about engine temp displayed, I don't see why instead of blocks, it can't give an actual reading ie 90°c does anyone know at what temp the cooling fan kicks in at.
As a sad person I have 4 Vf1000r, and one mod is a manual override, hit town/traffic switch on fan, or I found that pre Vtec vfr800 operates 8°c lower, so the fan now cuts in earlier.
As for the top box, oh yea of little faith. Givi OBK 58L it is a big, aluminium top box, usually found attached to mighty steeds like my gsa. Can take two full face helmets and additional accoutrements down the sides.
Or one man and his girlfriend's clothing for a week's touring.
