Well so far,
I can't say enough on how well the 2017 Tri Glide rides. The M8 has so much smooth and usable torque at hand compaired to my 103 and it ran pretty good.The gear ratio on the 2017 is spot on and is matched well to the trike. The drive train and tranny is the smoothest to date on any Harley that I have owned. No backlash and the tranny clunk is pretty much non existent. The shifting is so smooth I am very pleased with that.
The wife says this is the most comfy Harley that she had been on to date and loves it.
One big thing that emproved things big time on the trike was floorboard extensions as well as a rear extended shifter arm. All this after being properly adjusted made shifting and floorboard room a breeze for me. Also the drivers backrest a big plus as well.
The 2017 in stock configuration runs just fine for me and our style of riding ( safe and sane..Lol). For the guys that plan on doing more to the M8 you should have power to spare.
Ride Safe All,
Bill G
