Why don't you Metric haters stay on the HD forums for crying out loud. Just answer the mans question if you know it and if not shut up.
To answer your question, the Roadliner is by far the better of those two bikes. You won't regret buying it if you like to ride and love power. 1900 CC's (1854 really) put a lot of torque to the ground and it handles like a dream. Either way have fun and keep the shiny side up. And smile at the haters as you ride by.
