I do not believe so.
Can anyone tell me if I can install a 54 tooth rear sprocket using the stock length chain?

Way too many past bikes and builds to list. I won't bore you. Questions? Just ask.
When you change out your sprockt, get yourself an O ring chain. You won't be adjusting your tension very often. As those stock chains stretch they start to wear on the teeth of the sprockets. I am running 60 teeth on my rear. Sure helps out on the trails where mostly you are just putting along under 15mph. I don't mind running the back roads at 50.
Hi dlddd34, and welcome to the forum!
How many miles do you have on your stock chain?
Good(?) news is it may have stretched enough that it will work with the larger sprocket, the bad news is that if it does work then it is time to get a new chain.
Plumbstraight, where did you get your 60T sprocket?
These guys supply all sorts of sizes. A 60 tooth for the TW starts at around $81 plus shipping.

Another option is to drop a tooth count on the front sprocket. Going from 14 to 13 teeth in the front is about a 9% change while going from 50 to 60 teeth in the rear is about 12% change in overall drive ratios.
Just to muddy the waters and make you folks break out the calculators I run 13 x 55 sprockets turning a 26" nominal diameter ATV tire.

Any sprockets greater than 55T are aluminum. I've read in this forum, that aluminum = bad, steel = good.
Do I need to be concerned about the larger sprockets being aluminum?
I've used the calculator to see that I can get a similar torque improvement by going to a 13T front and 55T back. But, again, I've read on this forum, that 13T=bad.....
So, I'm torn between going 14T front and 60T aluminum rear
13T front and 55T all steel.
Hi Rorr, and welcome to the forum!
There is nothing inherently "good" or "bad" about aluminum or steel sprockets. It all depends upon the characteristics that are important to you, such as:
-Weight - aluminum sprockets are typically lighter than steel
-Durability - steel sprockets are typically more durable than steel from a wear standpoint
-Appearance - steel sprockets can rust, while aluminum sprockets don't rust (although they will oxidize)
-Cost - not sure about this but my guess is that they are both comparable
-Availability - some sizes are only available in either steel or aluminum
Again, there is nothing inherently "good" or "bad" about 13 or 14 tooth front sprockets, but there a few things to consider:
-Rear sprockets are generally considered to be easier to change than the front sprocket. Also less chance to pinch wires if the front sprocket is not changed.
-With the 13 tooth front sprocket, the chain is required to travel in a slightly tighter radius as it goes around the front sprocket. Theoretically, this may result in greater/faster wear on both the chain and the sprocket. From a practical standpoint, this is most likely inconsequential on a TW with a whopping 12 hp (claimed).
Since you haven't told us where you live, what kind of riding that you do, and what if any mods your bike has, there may be other considerations that we are not aware of.
Hope this helps,
I just bought a 2008 with 6K miles on it. It has been driven exclusively on the road. Everything is stock.
It clearly needs a new chain - has original
I plan on replacing the chain and both sprockets
I intend to use it exclusively on trails/forest roads. Primarily as a hunting bike.
I’m a pretty big guy - 6’ 3” 275lbs
I want something that I won’t have to be slipping the clutch on steep terrain
Expense is always a factor. I can get a 60T sprocket for $65 at pbisprockets.com. 55Ts are $25-$30. Anything bigger than 60T runs $80+
