16 tooth much better for the highway and possibly not too high for easy off roading. It'll drop the RPMs 500 throughout the range. Sun sprockets are good. No after market sprockets wear as well as the stocker, plus they do not have the rubber on them. Just saying. Also do not just change a sprocket and not the chain IF the sprocket is worn in any way. The chain will be worn also if old etc. Then you need to check the rear sprocket also. Sorry to cause you to spend more, but in the long run it's best to change them as a set.

I keep hearing that going up 2-3 teeth on the back sprocket helps on the dirt, I guess depends on the kind of riding you're going to be doing more often...?
I just wish this thing had a 6 speed transmission I always find myself looking for 6th hehe

Sun is a make of after market sprockets, the stocker is from the dealership. They only sell the 15 tooth sprocket that came with the bike. It will last longer, but you won't get the benefits of lowering your RPMs IF that is an iterest for you.

The easiest way to get a drop in gearing is to use a 14 tooth front sprocket and leave the rear alone. It is easier to change the front compared to the rear also. Not to mention cheaper.

That's a great point for some odd reason I've always found the rear sprocket easier, maybe it's because I've changed so many tires on so many different bikes already, but I think I'll do the 14t for now, after all, my bike only has 4700 miles and the chain and sprockets look brand new

i went ahead and ordered a new front and rear sprocket and chain, rear sprocket and chain can be backups in case of emergency.

IMHO, replace it all at once and keep the old change and sprocket as a back up. That way they all wear together instead of the sprocket wearing a new member of the set. If one member of the group is worn it will wear the others at a much faster rate than if you change them all out at the same time.

The long distance boys on ADV wear out 3 front sprockets for one rear and chain. This makes sense as the ratio is nearly 3:1.(43/15) They buy 3 fronts and rotate them on a regular schedule rather than waiting till one front is worn out. This way you are not running a brand new front on an old chain. Food for thought!
