The dealer we bought the bike off of is new to Triumph so I called a dealere in the area with many years of experience.
They said bring in the bike so they can try it to see if it is what they would call normal or abnormal.
They said it is possible that there is a kink or twist in the cable causing resistance.
Saturday my wife and I will run down and have them look into it.
I have been searching out the throttle assists such as the Throttle Boss.
I will also look into the Rocker you mentioned.
But my hand actually starts to cramp up at times due to having to grab hard for long periods.
Are there throttle locks out there for the Rocket?
We have had issues with the Rocket and I do not want to be picky but for the cost of the bike and the fact that I have never rode a bike with this bad of a throttle makes me want to get it addressed.
Thanks for the input and stay tuned for Saturday's update as to what, if anything, they may find.
God bless!!
