Does anyone know whether the throttle sensitivity can be adjusted? Ever since my bout with arthritis in my right hand last year it just seems like its hard to hold a speed/rpm steady.

 

These beasts are jumpy.
Slide your throttle hand up so it slightly touches the throttle grip housing to steady things and use the cruise control as much as possible.

 

Know where your coming from, try a Crampbuster throttle assist best 10 dollars you will ever spend and so simple.

 

FP3 allows you to adjust throttle response.
All the M8's i've tried had twitchy throttles. My Breakout got a lot better as i piled the miles on.

 

Could fit the cruise option?

 

If your bike didn’t come with cruise, you can add the left control switch pack, and have the dealer enable cruise,

Thanks for all the responses. I do have cruise control and use it almost to a fault. I have also tried sliding my hand against the switch housing with some success.

 

I have similar issues with my right hand. Large bone spur from an old fracture. Also have chronic "golfer's elbow" (medial epicondylitis). Hand aches and goes numb when riding. Same thing happened last year and got prednisone in late May. Helped a lot and allowed me to take a long ride last July when I had my 2017 XL1200T Sportster. No cruise on that one, but a cramp buster allowed me to do the 1600 miles in 5 days of riding. Still had to stop about once per hour.

I now have a 2018 FLCHS (Heritage 114) with cruise control. This helps, but I just went back to my doc for another prednisone dose. Doc referred my to a hand ortho. I'll work around it this riding season, but may have to have surgery next Fall/Winter to really make it better. It's not going to stop me doing the trips I plan for this summer (back East again and a trip to see the Rockies).

Edit, posted to a different thread, but it ended up here?

 

Yes, it can be adjusted with the H-D Street Tuner. It's called throttle progressivity.
