I guess there's motorcyclists, and then there's motorcyclists. When the Triumph Rocket III came out, a member of my local Ulysses Club (over 50's motorcyclists) was diagnosed with terminal cancer. The cancer was debilitating and was a "week by week" deal, and even with the chemo treatment he lost lots of weight and couldn't hold a bike up.
He didn't buy a Miata, (he might have bought one for his wife, perhaps) he was a biker, and proud of it, so he ordered a new Rocket III and had another member who does trike conversions to build him a Rocket III trike, the first (and maybe only) one in Australia. He lived for another 18 months or so, and none of the other club members questioned his trike ownership.
I'm surprised (and slightly saddened) that some folks here are so anti-trike. Anyone who's ever owned and reguarly ridden a sidehack will tell you that they're not all that easy to live with, and require a high degree of skill and concentration to master, and a trike is a good thing for those who still love motorcycling, but for reasons beyond their control, are no longer able to ride a two wheeler. Motorcycles are motorcycles, and cars are cars, and never the twain shall meet. Cheers, Terry.
