Are you ready for a lengthy list of "I wants"? Most anybody that's been here since I came along that my pet peve is the non powered windshield adjuster... I mean come on Honda, it's been on the ST since Adam was a pup! Now a couple of my 'inside' sources say that's actually a priority so I'll give that some rest.
Next I'll say that there will be a serious attempt at a weight loss program, say in the neighbourhood of 50 lbs. After that I'll suggest a performance gain to boost the output up to somewhere in the 150 hp range. Twin cams, variable valving, different/improved induction (ram air?) or some combination of those things. Drive by wire?? Transmission upgrade: dual clutch, 6 speed maybe. New front forks with variable and adjustable dampening; good bye to that goofy archaic set of internals that (ahem) have worked for almost 3 decades but is waaaay long in the tooth. A bit more cornering clearance, doesn't have to be much if they succeed in loosing thos pounds above. Still more improvement in the seat and legroom department.
Now the hard part: Keep it a Goldwing!!! Long haul durability that we're so used to, low maintenance, keep the sillouette and overall package (luggage room and luxury) as close to what we have now as possible, and most of all, don't make us puke when we see the sticker price!
Disclaimer: other than what I mentioned about the windshield, none of this comes from Honda House rumour mill, it's from my heart and wish list only.
