1 year 2 months, 2017 Ultra Classic *8/16 build*, 10,360 miles.
Zero problems

 

18 Road Glide 107...2 months 2000 miles....no problems.

 

Purchased '17 CVO Street Glide in November of 2016.
On 10/4/17 I had 3691mls on original engine, including two oil pump replacements. Due to low oil pressure light again, I received a new engine, since oil jet (mounts) missing at least one screw and were mis-aligned.
About additional 3800mls on engine/ 7500mls on bike since then. So far no issues.


I hope that helps.

Bought in April 17 - put 7500 miles on it until it started snowing in December. I ride to work almost every day after the snow melts, but my office is only 6 miles from my house! Lots of miles on the weekends to make up for it though!

 

Bought my SGS late Feb 17, 8500 and I work full time 1 mile from my house. Can't even ride to work so I try to make up for it on the weekends. Just traded my 15 Heritage with 16,500 on it ( for a 16 VRSCDX w/ 8 miles )again all week end miles.

 

16,096 on my 2018 FLHR.

No M8 issues, yet.

 

Clutch recall and vent tube primary install.
Stage 2 that I installed my self. Thunder max tuner, Woods 222 cam. S&s lifters. So far, zero issues.

 

17 Road King I put 36,000 trouble free miles on it in 19 months. Traded it on a 19 Street Glide August 2 and have 6000 miles on it so far trouble free as well.

 

Not enough ! (to the OP's Q)

Peace.

 

I have 6019 miles in my 19 FW 114" in the 7 available weeks I've been able to ride. No issues.
