I don't know, I took my first ride on a 1600 Thunderbird today and I am still undecided. It has lots of torque down low but it feels like it runs out of steam on the top end. The belt drive is nice and smooth, I could hardly hear the engine running going down the road and I took it up to 110 mph. My bike feels snappier on the top end. A new exhaust might let it breath a little better and after reprogramming it might perform a little better as well. I still want a ride on a new Rocket Roadster and maybe a 1700 Thunderbird.
