I could say you won't be sorry for going to a trike,,, but then it is each to his own.
For us, we test rode a Spyder for a day,,, a whole day, two up, and that was a mistake. I should have got used to it first on my own and then added a passenger. Then we rode a Hannigan (B2 Dad's) to compare the difference. We found a lot of similarities, and at the time the Spyder only had 2 cylinders so had vibrations which we found to be disagreeable. This year CanAm came out with a 3 cylinder, we went to try it and I was sold,,, except for the price,,, ooooooo that was a hard pill.
We now have 3000 miles (5000km) on it and don't want to go back to the Venture. This thing is stable, fun, smooth, (not quite as smooth as the Venture but quite acceptable) and has reverse... a real reverse,,, got to be careful. It tracks real well, (a feller needs to do an alignment on the front for this to happen), mileage is 36 American, 43 Canadian.
It now comes with a 1330, 3cyl that pumps out a fine 115hp. Lots of get up and gone. Crank this baby out and you'll be glad you have something to hang on to. Lots of good features on the Spyder, but price is not one of them.
For us it was, that slowly on, things were getting harder to do, mostly Marca's knee at this point, and if I watch my friends they seemed to be having this thing about getting old, so I figured I was going to hit the same patch in life someday. As was told to me, you are better to make a change when you are able, rather than after you have to, so the switch was made,,,,, made a lot of sense, and,,,,, worked.
