Let's face it; trying to beat the reliability records of a GoldWing will be a losing battle for EVERY other bike! nojoke
That having been said; the Spyders keep getting better and better! There are several out there now, that are well over 100,000 miles. I know of at least one, that has never even had the valve covers off of it in that time.
The 'Wings have been chasing horizons for over 40 years now... :bowdown: It will take a LOT of time for anyone to match their records.
First, welcome to the forum. :2thumbs:
I agree with what Bob Denman said above. It's very difficult to compare a Spyder to a Goldwing. The Spyders have only been on the market since 2009, although BRP has been making recreational vehicles and engines for many decades (off-road 4-wheelers, snowmobiles, sport watercraft, and engines for all of them, plus Evinrude marine engines). The Rotax V-twin engine has been used world-wide with exceptional reliability for many years. The new 1330 in-line 3 cylinder they made for some 2014 and later models seems to be just as reliable, if not more so. If you look at Consumer Reports, you will see a higher incidence of service calls on Spyders than many other motorcycles, but that is misleading. Not only is the Spyder relatively new, but it has many complex safety systems, like those common to late-model automobiles, that are simply not found on any other motorcycle. And as Bob says, they are getting better every year. The vast majority of Spyder owners enjoy trouble-free experiences similar to that of any other well made motorcycle.
As for trikes, my suspicion is that Spyders are just as reliable, if not more so, than any other trike on the market - factory made or conversion kit. But most will agree that, with the two wheels up front, they are much safer, much more stable, more maneuverable, and much more fun to ride than any other trike.
Go test ride one or two, and see what you think. :thumbup:
