The Rocket is not the only cruiser type Triumph makes, there is also the Thunderbird series, of which the Thunderbird LT probably has everything you want, except it comes up a little less on the power vs a V Rod.
I was surprised a few years ago at how agressive Triumph has become in the cruiser market, they just don't have the dealer network to support them like HD does.
Of course, the Triump after market (dealer) accessories is less than HD, and probably just as expensive. I am not sure if you can load a new MAP into the Thunderbird ECU or not, Triumph has locked down some of them.
