Dimable dash lights: my Monster has a dimable lcd dash. It's nice...but needs to dim even more. I agree - stop blinding me at night!
Fully customizable lcd dash's with skins: seriously: just start putting up a 4x6 dash that a flat, touch screen lcd. Let me PICK what I want to see. Highway cruise? How about a HUGE MPH number and smaller temp, fuel range, etc. skin. Or if I'm on the track: HUGE RPM and Coolant Temps...It's not like I give a rats poop about RPMs when I'm droning along at 65 on the freeway...
REAL Throttle by wire settings: Hey, just because YOU think a rain mode is needed and that neutering my bike means something doesn't mean it does. What I want is to control the aggressiveness of the throttle - not the powerband, not amount of throttle. In the rain I want simply a soft delivery in the first 75% of the throttle...but full power if I need it. I want to tailor that throttle myself. I don't want to mess with fueling or anything like that - I do want to control the way the throttle works.
Cruise Control: with throttle by wire here, please just make Cruise a standard feature.
Real maintenance intervals: how about figuring out a way to indicate what really needs to be adjusted for maintenance? Like, don't go tell me to check my valves if none are out of spec? Surely there's a way to know when the valves are out of spec? And come on, why should riderse have to go out and buy a GSG9 computer to figure out default codes? If you've got a full custom LCD display, just have a "maintenance" screen and post the issue there.
I'm sure there's more...
