I've never yet bought a motorcycle with the fear I better no buy that just in case it falls over and it has not fall over protection.
Yes I've taken aftermarket steps to try to minimize damage in case I crash it, but this protection doesn't even enter the back of my head in my buying decision.
If it had, I wouldn't have bought most of the bikes I own or have owned. The fairing alone, on my Bimota DB2, that cost me $15,000 OTD, was $4000 to replace.
The Wing is a fabulous motorcycle and I thoroughly enjoyed mine, but if I was laying down the best part of $30K on a new 2017+ touring motorcycle, I most likely would go with the BMW.
The BMW, to me, just has more Pro's than Cons over the circa 10 year old design of the Wing at this present time.
If Honda chooses to do a serious 2018 redesign of the Wing, I'm sure we'll have a very similar thread arguing why the new Wing is not better than the current 2006-2017 model, but hopefully the new Wing will still have parking lot protection....
