Bought a 400 drag sled, Talk about kick back. Test road a 1100 CC but the ride position just killed my back, power was nice. But the 400 has enough for me. I usually poke along around 110 anyway, anything past that is really waisted when I ride. Got the book so good to go for Lao when the weathher gets good. Not nearly a responsive as the 535, but a heck of lot more comfortable ride.
