A couple thoughts of why Spyders don't attract the TT crowd as much
First off ... not bashing any bike/trike. I test rode a Spyder and came within a whisker of purchasing it. Fun to ride, a look I could of got used to ... and very interesting.
SO ... here's my take on the Title of this post:
1) most TT members have ridden something for some time. Just meaning they have been in the wind for more that a week or so ... :D
2) when you get into this crazy lifestyle, you tend to gravitate to a style and make. Some like cafe racers, crotch rockets, cruisers, big heavy touring models, etc. Or, Honda's, Yamaha's, BMW's, Harley's, etc. (yes I know I've left out several styles and manufacturer's).
3) my personal experience is that I like to try new things ... but I always seem to gravitate back to big Harley Touring bikes. I don't think anyone makes a better touring machine than the Honda Gold Wing.
When I ride a Gold Wing around town or on the road ... very few people look. When I ride a Harley ... my heart pounds with excitement and everybody looks ... half are annoyed that it's making noise and they think it's dangerous. The other half are having the same visceral response that I have when riding a Harley.
So is it pride or narcissism that leads me to a Harley??? Maybe. But, here's why my heart pounds. The engine is right there for all to see, not covered in plastic. It shakes, rattles, and yep ... requires more love to keep it going (I'm sure that's part of why I have the attractions to Harley's ... they seem to need you as much as you need them).
So .. now that you know why I keep coming back to Harley's, maybe it makes it easier to understand why most TT riders seem to gravitate to what they rode before 3 wheels and loved. Along comes the Spyder, the Slingshot and others and they are outside the "comfort zone" of many riders, no matter how attractive they are. I will admit, it usually takes something dramatic to get a Harley rider to come over from the dark side. Harley love is a special kind of sickness ... LOL.
