I need new chain and sprockets for my 2017 KTM 450 sxf.  Currently looking at dirt tricks sprockets and DID XRING chain.  Anything better out there?

What about sprocket teeth?  Stick with standard or change ratio?  

This will be 90% mx track use in Middle michigan.  Thx!

....also, looks like stock is 13/48T sprockets and 118 link chain.  Thinking of going to 14/52T and 120 link chain.  If I did, would the chain be too short?

I run 14/52 on my 250 2 stroke and use a 120 chain and normally need to cut off a few links. The chain angle is changed which helps the rear suspension work without binding. Red Bull KTM runs that gearing for that reason. It’s not much of a ratio change so you’ll be fine, it will just pull harder down low and top out each get a few feet sooner.
