Although it isn't what you'd call a trike, and it's engine displaces a bit more than 150cc....I do have a three wheel vehicle that I totally enjoy. They are a 'horse of a different color', and must be ridden/driven more conservatively. Because of the added weight, and wind resistance, their performance will always be less than a 2 wheeler with the same power plant.
At 69 years old, I'm not ready to give up my 2 motorcycles, or my scooter, but, if I live long enough, the day will come, when I'm physically unable to handle the BMW's. Then the 3 wheeler will become my eveyday ride.
