Airbags in cars have been in constant development since their introduction in 1972. It has been a very long gestation period indeed. They are finally working pretty well, with the advent of side curtain technology, knee bolsters, smart bags and such.
I guess my point is that the front airbag alone only works (well) in a limited number of situations. IE: Head on.
While any supplimental protection may be better than none, I have not read or heard enough about Honda's airbag design intent to make a reasonable descision. Too many questions remain:
*Is it best to 'Stay' with the bike under all conditions?
*Does the airbag hold you in so on a layover your legs are at risk?
*At what speed or G-Load stop is it activated?
*How is its performance with a Pillion aboard?
*What if you are wearing an open face helmet or have your shield up?
While I am not against technology, or passive safety, I can't help but wonder how much marketing research was done in the FEAR ZONE of older riders.
I have had two bad crashes. 25 years apart. I walked away from both because of protective gear. ATGATT!!
But, I have been saved many more times by active safety: Great brakes, good training, correct tires, chassis dynamics, sleep and water etc.
So, I think I'll wait and see how the next couple of years of real-life on-road testing goes, who is saved and who couldn't be saved no matter what.
