i am considering buying a tw200. my uses would be just around town on 35mph roads with most of my time spent in the desert or the mountains. i am wondering about the first gear on the tw200 with stock sprockets. how slow can you go in first gear up hills or in very technical and difficult terrain without losing power or riding the clutch?

to put it in perspective i used to own and ride a rokon 2 wheel drive atv. the thing i liked a lot about it is that you could do 2 or 3 miles and hour with lots of power available to you at those speeds and so could do some pretty gnarly terrain at very slow speeds. i am wanting to recreate some of that capability with the tw2oo.

im wondering if i ought to change my sprockets to get a really slow climbing gear.

Buy it. Try stock gearing before making changes.

1st is a crawler gear, stock. If you want a granny gear, sure, change sprockets.

Plenty of folks here have swapped from the 50-tooth rear sprocket up to a 55, or other sizes, if they felt they needed to lower their gearing for terrain, based on rider/gear weight. This WILL cost top end & cruis-a-bility on-road over 45mph in the form of high R's.

Swapping the front counter sprocket isn't needed & is more difficult anyway, as it requires you to remove the left-side engine case cover. If you're in there for another reason anyway, fine, but don't make a special task of it.

Rear is an easy swap & if you're buying the bike anyway, you'll want to try it stock to get a baseline for your expectations.

You may need to lengthen your chain, depending on your choices.

Lots of info on this if you search the forums, re: sprocket combos, gearing, what to use where, etc.

Oh man, you are going to love a TW200. A slow 1st speed tractor gear, and when it comes to pavement, the T-Dub loves 35 mph roadways. Most of my time on road is spent at 35-40 mph. To me seems to be the perfect loafing along cruising speed for the low geared 200.

Many on here will cruise at 55 or better but the thing just sounds too busy to me at that speed especially for extended times. But, the bike will do it all day long and laugh for more of it.

For what use you speak of above, you will have no regrets in my opinion.

Welcome to the forum,

Marty

Welcome aboard, brother! It all depends on the severity of your "very technical and difficult terrain." Here in the CO Rockies, I've done some pretty crazy stuff with the factory rear tire and sprocket. With that said - I also have a second rear wheel with a Duro Atv tire and a 70 tooth aluminum sprocket. Sounds like you might want to tooth up the rear a bit.

Stock gearing of 14tooth CS sprocket and 50tooth rear sprocket, 1st gear, idle is at approx. 1300rpm. Here is your speed based on RPM;
1800rpm=4mph
2700rpm=6mph
3600rpm=8mph
4500rpm=10mph
5400rpm=12mph
6300rpm=14mph
7200rpm=16mph
8100rpm=18mph
9000rpm=20mph
Top speed in 5th gear @9000rpm is 69.7mph

Those who prefer a lower 1st gear usually swap out the rear sprocket for a 55 tooth rear sprocket. Here's your speed based on RPM with a 14tooth CS sprocket and 55tooth rear sprocket;
1800=3.7
2700=5.5
3600=7.3
4500=9.2
5400=11
6300=12.9
7200=14.7
8100=16.5
9000=18.4
Top speed in 5th is 63.4mph

If you want a lower crawl speed, then a 13tooth CS sprocket in conjunction with a 55 tooth rear sprocket gets you these speeds;
1800=3.4
2700=5.1
3600=6.8
4500=8.5
5400=10.2
6300=11.9
7200=13.6
8100=15.4
9000=17.1
Top seed in 5th is 58.8mph

"Steep" and "Technical" are relative terms that can mean different things to different folks. You might think my opinion of "technical" might be milk-toast easy in your experience. However my solution to your very same concerns resulted in an ATV tire spun by 13x55 tooth sprockets.
So if you get a TW there are options from stock to wild that should satisfy. Try stock gearing first but even without knowing the location and terrain I guess the 10% final drive ratio change with a 55 tooth rear sprocket would be appreciated.

What resource did you use to find these numbers?

I have the third set-up in Ski Pro's post. When I get up into the mountains of Colorado I need that because the TW doesn't have much power above 11,000 feet. The rest of the time I find the 13/50 combination to be just fine. It is a dual sprocket set-up, but 98% of my riding, including steep stuff is with the 13/50. I can still go 55-60 with that.

I too had a Rokon first, and there are still some highly technical trails I won't do on the TW, but being able to cruise to your riding venue trumps that easily. I would put a 55 on the rear first, since it is easier to change than the counter sprocket, and you might find it just right. That is very close to my 13/50 setup.

Stock gearing works fine for me. First is walking speed & works great for the technical situations I find myself in out here in Anza Borrego desert. I have never wanted anything lower. On the other end of things I don’t normally push it much over 50 on the street, although it is capable of more. I prefer to cruise at 45-50. Great, fun bike.

I used this website. Stock 14/50, mine 14/55 and custom 13/55. That way I can compare all three at once.

Be sure to load in Yamaha TW200 and year at the top of the page. You can set it up for any gears you like to try and it will calc out all 5 gears individually.

I know that numbers can't lie, but 20 mph in first with stock gearing doesn't seem possible. Perhaps I have a lot more revs left before redline than I thought. I guess I know what I'm trying tomorrow.
Thats the same thing i thought. Ive never tried to top out first gear and see how fast it will go but 20 seems like alot. I live in town so the speed limit in town is 25. If im cruising down a long straight away in town, im in 3rd going 25.

hello
unless you have many years of motorcycle riding, especially single cylinder thumpers, and even then; you should have:


or something like it.
out of all the frakles that people apply to their TW this gadget is the one that lets you know how hard or not you are working the engine.
i thought that i knew what 7000rpm sounded like, nope i was off by 2000. instead my fear of over reving never let me get into the "power" zone of the 12 horses that we have available.
now when i cruise at 7500rpm, yes it is noisy, but i can see that i am below the redline. i think i saw 9100rpm once and there is no need to push it THAT hard.
7500rpm with 15/50 gives me a 60-65mph.

I used a 65 tooth on one of Fred's rides. What I really liked was that: coming down a steep trail from Crater Lake (California; not Oregon); those in front of me in 1st gear had their brake lights on almost constantly to keep from going faster than was safe. I was not touching my brakes; and was shifting to 2nd at times to close the gap.

Most of this video was recorded in what I would call mellow terrain while in 2nd or 3rd gear with 13 x 55 sprockets with engine just off idle. As old w/?? points out this saves first gear for steep, loose, or otherwise technical ascents and descents like around the 2:22 minute mark. I've ridden here before with stock gearing, as well as with others also with stock gearing. We did just fine with stock TWs...nothing is perfect though, sometimes we wish to go faster, sometimes slower but is all fun.

Yes, I have a small digital tach sitting in it's box waiting to be installed for 2 years. Maybe soon. I bet I will be surprised.
