I have a '02 GW with a '05 Motor Trike kit with 61,000 miles. I have a 2011 Can Am Spyder RT-S with 4,600 miles. I really like both. They are different rides. Yes, the GW has more torque and HP, but the Spyder will run, you just have to get used to running 6-7,000 rpm through the gears. I have the semi auto (paddle shift) which I really like.
My Spyder has 80# torque and 106 hp. It red lines @ 9K with a rev limiter at 9,200.
One of the comfort/handling secrets to a Spyder is setting the front shocks and air pressures to suit your type of riding and weighs. My rear suspension is electro hydralic and adjustable to my needs.
Standard is power steering, ABS, traction control and electric windshield.The matching trailer is a neat accessory.
For short trips of 300+/-, I take my Spyder, for travel, I take the Wing.
