Pulley/sprocket swap
2018 883
Looking to decrease my rpms at highway speeds. I travel about 30 miles to work and run 70. I just dont like all of the vibes when I need to pass at about 75-80.
My question is should I swap the final drive pulleys or the primary drive pulleys?
Also does anyone know what the stock final drive is on my bike? Can't seem to find it.
where can I find replacement pulleys for this?

The difference in the US models will be in the primary I believe from 2007 and later.
Harley and others offer a larger front pulley, from the International models.
Your
.1200..........883
38 / 57 34 / 57
Primary1.500 1.676
Final Drive ratio 2.345 2.345
(57/34) x (68/28) = 4.07 overall in top gear (stock 883)
(57/34) x (68/29) = 3.93 overall in top gear (883 primary & 1200 final)
(57/34) x (68/30) = 3.80 overall in top gear (883 primary & HDI final)
(57/38) x (68/28) = 3.64 overall in top gear (1200 primary & 883 final)
(57/38) x (68/29) = 3.51 overall in top gear (stock 1200)
(57/38) x (68/30) = 3.40 overall in top gear (1200 primary & HDI final)
