Thank You Puc (Steve), very good write up, and now understanding the Vmax a little better. More top end is always nice, especially on two wheels, but as you mentioned it is rear end torque this RSV-Trike really needs, and it was more of a inconvenience than a issue.
But at the same time riding with friends being two up with a lead foot on his hoped up engine wasn't a fair comparison to the loaded RSV.
Dave & Maria seen how much fun Charlene and I had on a trike they traded in there 07 ultra for a 2019 harley tri-glide with the 114 engine. Hope they can keep up, lol.
Now that our trip is a great memory and back to riding Michigan roads, not mountains, I will see how the RSV-T performs for 90+% of our riding. However, I will contact Hannigan to see what they think about which rear end upgrade.
Thanks again Puc for your thoughts, most appreciated, Later-
