That all depends on how new your existing chain and sprockets are. If they are pretty much brand new, either no rides to like a few hours on them, then no you do not need a new chain.

Typically you must replace all the chain and sprockets at the same time.

Point being that if you have an evenly worn set of chain and sprockets on the bike, and you get a brand new rear sprocket, you will tend to wear the new sprocket prematurely and possibly skip teeth at high speed. This can happen because the old chain is slightly stretched, and the old sprockets' teeth have an increased gap from the torque applied to them. The stretched chain and the fresh new sprocket will therefore NOT mesh properly and exactly, to possibly cause the chain to break, pop off, and/or wear the new sprocket prematurely.

So do you think that the stock chain is long enough?? Or, do I to get a new one?

Yeah, your quite the helpful one.

Anyway to answer the question, I think you will be ok as far as the hours on your chain. You can get a different sprocket and throw it on w/o replacing everything.

However, as far as the stock chain being long enough, you are going to have to make that desicion based on how far you have to move the chain adjuster. If you can move it forward enough and get the proper slack, than you are good. But if you can't get the chain connected after putting on the new sprocket becuase the slack is too tight, then you will need a new chain.

Your chain should be long enough.

I run 50 and 52 tooth on the stock chain.

There is some adjusting of the chain adjusting bolts though.
