I am not sure the differences but i like the speedo set up on my 2018, i was dissapointed that the knee pad did not have the blue stitching. I wish they had the M stripes in the seat belting. I like those little details.
Outside of that give me any M2 and it is better than anything out there. You can never get that perfect detail for every person at a price point we can all afford. I am just glad I pulled the trigger on getting one.
