I have a 850i trail I am going to sell and the person wanted to know if coming off a mountain did you have to give it gas to make it hold back or was it like a Honda where the engine held it back. I have never had it on a mountain and couldn't answer his question. I would appreciate any help if anyone knows.
Newer builds I think starting in 2015 have engine braking. Otherwise must give some throttle to engage primary clutch.

Looking at the parts diagrams available on JDPARTS.com, it looks like the clutch and primary are the type that provide engine braking when descending hills. There are no part number changes based on serial numbers, so one would assume the design has remained constant through the model run.
Hopefully someone with a similar machine will confirm it provides engine braking.
Wish I could be 100% positive, but this is the best info I can provide.
