Getting ready to order new sprockets, currently have a 47 rear on(what was on when I bought it). just wanted some thoughts on 45 vs 47 for 50/50 riding. Not too many hills here in S. Florida

mine started out 14/47. keep the 47. PO gave me a lightly used 45 too so don't think that really works very good unless your only on pavement.

My riding is mostly in the city. I just changed from stock 14/50 to 14/45 and the difference is more significant than I was expecting. I am 165# and the only real sizable hill near me is a 30 mph speed limit so not much downshifting for me just yet. I have a 15 tooth front that will be going on as soon as my X-Ring chain arrives. These little bikes are never going to be freeway cruisers, but the biggest difference that I've noticed is that I no longer feel like I'll be freight-trained by the horrible drivers around here. The TW203 and 204 tires also made a HUGE difference over stock. I don't miss the knobby rumble and the old front Deathwing had given me a few "pants-filler" moments.

If you can get a good deal on the 45 (check lugnut above), you should give it a try. If you are putting on a new chain with the new sprockets; use the old chain to test the 45 before you size the new chain.
If 47 worked fine for your off-roading conditions, then hopefully the 45 would too, and give you slightly less vibration and smoother ride on road.

Tried them both. 45 14 gets my money. When I do go off road it is never technically an issue that the gearbox can't solve.

Went from stock 14-50 to 14-47.
Barely noticeable feel but according to my tach is does help the engine rev lower on commuting days. In retrospect it probably is not worth going from 50 to 47 though I'm glad I did it. But the bike is pretty perfect for what you call 50-50 the way it is.

The real mod here was the upgrade to the X-Ring chain and the JT Sprocket. Much, much better quality, especially the chain.
Even if you were not interested in changing the gearing at all the upgraded chain is so apparently better than the stock "no-ring" lowest quality one that comes on the bike.

I've been reading these posts and others like them because I'd like to run my TDub on state highways at 60-65 without over revving the engine. I'm doing very little off road and most of that is mild here in SW Ohio.

Changing the rear sprocket and possibly the chain seems straightforward enough. I'd probably leave the front sprocket alone. Can someone direct me to information on the forum that explains the process step-by-step? And recommendations on brands and where to buy the new sprocket?

While I'm asking, please point me to tire recommendations on the forum as well.

I ended up going with what was on it, 14/47 and a JT x-ring chain. JT sprockets also. I wanted little less buzzyness but didn't want to lose off road gearing toooo.. much. Got my sportster for the road anyhow. But agree the 45 would prolly be a better road gearing imo.

JRD; going to higher gearing can lower your rpms slightly to significantly noticeable. However it will not improve performance ability at those speeds because you just don't have the horsepower.
Usually most would recommend a larger bike for that speed range. I'm 200lbs and my speedo reads 4mph high in the 60s. So to do 65 the speedo has to read 69. When you get the bike up there; with higher gearing the engine may not be as wound out - but it will still not have anything left. Zero acceleration for any needed movement; and no ability to hold that speed on an incline.

All of that aside; the highest gearing I have seen posted here that works seems to be 14-39 (or the equivalent 15-42) on bikes the owners have done performance mods.
In testing my stock bike 14-39 equivalent 15-42 bogged to much on take-off to be acceptable.
14-42 equivalent 15-45 works fine on pavement (had not tried it off-road).
Borrowing a sprocket from Admiral to test; 14-41 and equivalent 15-44, was the highest gearing that worked without bogging - and lowered rpms the most (again not tried off-road).
That only leaves 14-40 or 15-43 as a possible higher gearing if it does not bog.

I used the 14-45 when riding with Admiral on his Three Fingers Gulch ride (easy off-road i would say) and it was fine for that.

As for street tires; go to the ProCycle website and look under TW's. You will find the two brands of street oriented dual sport tires for the bike.

As to the front sprocket: you've been on the forum 5 years this month; so if the bike is that old or older and depending on the miles - it may need to be replaced. Once you change the rear sprocket with whatever size you try; then if you want it to be even higher - you could go to a 15 tooth front (unless you went all the way to a 42 on the back - which the 15 would then make bog on takeoff).

Thanks Oldie, good insight and advice. From what I've read and for how I'm riding, the 45 tooth rear sprocket with the stock 14 front might be a good place to start. Mostly riding on country roads these days. My object is only to keep up with traffic on 55 mph state highways when necessary, certainly not on interstates. Scary thought!

Funny thing about this thread and it's inevitability of coming up again and again and again is that "50-50 riding" and gearing is subjective to what someone understands that means to them. I certainly don't go serious off-road 50% of the time... maybe 4-6 times a year. But I don't want or need another street bike either. I have other machines that will do that better than a 200cc TW.
Serious off-road or hunting, you guys know where and what you want. Same goes for street commuters. I'm in the 50-50 "want my cake and eat it too" contingent :)

You can flip over to practically any KLR650 Forum right now and find almost the same exact conversation. BTDT.

I did my first longer ride with my new 14/47 combo.

I think it’s a winner. The difference is subtle, but noticeable. I live in the mountains, and I think only once did I have to downshift to 4th to maintain 50mph on a long grade where 5th would have carried me up before. Still reached for 6th more than a few times, but at any given road speed things are just a tad less buzzy. But my impression was that 14/45 would be a bit problematical, at least in hilly terrain.

Did some off-road on relatively easy logging/fire trails, and 1st gear was more than low enough for those, with 2nd usually being fine for hills.

As an aside, it’s amazing how torquey that little 196cc motor can be when committed to a slightly too-high gear on a hill!

Good for you that your pleased with the change even if its subtle. Once you do this it's easy to go back & forth or join the dual sprocket gang which is very cool.
For me the change to the 47T hasn't prevented me from looking for that proverbial "6th gear" on occasion but then again I'm looking for it on all my bikes sometimes.
Have fun.
