I've had the 16t (stock sprocket), the 18t, and currently the 17t. Chain will work, no problem with any of them.

You adapt to what you have. I liked the 16t for the first 8-10k miles (I can't remember), then the 18t made it a whole new motorcycle, and then I put the TRIUMPH America chain and sprocket kit (with the 17t front sprocket)on, and I'm just as happy with it. I even think seriously about going back to the 16t next chain/sprocket change....I liked it when I had it, and the bike runs so good over 5k rpm I think it would be fun to be able to run the higher rev range on the highway more than I can now.

You can't go wrong.
