Hello Guys,

I have a Yamaha TW 200, year 1996 or 1997
I would like to change the rear sprocket from 50 to 45
I live in Italy so IDK how much I can find online
Can You suggest me which exact model I have to purchase?
I guess the "kit" must have the front and rear sprocket and the chain right?

Can You point me with a specific model or maybe something I can purchase from Italy?
The shops we use are ebay.it and amazon.it
sprocket in Italian is "corona" and tooth is "denti"

I hope someone can help me with this ^^

EDIT: forgot to mention, the front one is 14
So I guess I have the "stock" sprockets 14/50
I would like to get 14/45

Go here to figure out which year your bike is. http://tw200forum.com/forum/general-discussion/10362-tdubs-year-photo-collection.html
But keep in mind these are pictures of the US models and might not match up with the EU ones.

What is your reason for going to a 45 rear sprocket? You will go only a little faster at top speed but lose the low end power for riding the trails. 14/50 is stock and your TW should cruise easily at 55 MPH with this gearing.

I am a fairly light guy so the low end power is not a problem, also I don't really do any trial
IMHO the 45 one in the back is the most balanced compromise so I don't have to always "pull the engine" with very high RPM in 5th to have a decent speed on the highways

Very interesting! Our TWs here don't have a 5th gear but we are all always looking for it. I think it is possible the Japan/EU TWs could have 5 speeds but don't know that for sure. The 200 CC engine is very short on power so a 45 in the rear might be OK on flat roads but not here in the mountains I live in.

Never mind! This was before my morning coffee :stupid:

I think 14-47 is a little better compromise. 45 is just a little too tall and you might even lose top speed on moderate hills. If you were going to only ride on road I would look for a more powerful motorcycle.
And I think Gary means 6th gear...

Gary, 5th is located one click up from 4th. :p
YUP! But I was not quite in 1st gear when I made that stupid post. My last manual shift truck was a 4 speed and I was always wishing for a 5th gear. On my TWs they too are missing the last or 6th gear.

I couldn't resist, GaryL!!! hehe I almost said you should have bought a Canadian model...ours have 5 gears so they work correctly with the metric system.....

I don't have a lot of time on my 45-tooth rear (Sunday's ride and last night) but so far I'm liking it. Went out for my ride yesterday after work, to get to where I was meeting someone you can either jig-jog through town or take the divided highway that does a 3/4 circle around the city. The speed limit is 100km/h and with the 45 I had no trouble doing 100-105 for the 4 or 5 minutes I needed to be on it. There are time in town, and where I fish, that I can jump on the highway for 4-5 minutes to get to the next area, or I can take a 15-20 minutes detour to get to the same place. If I'm out for a ride, I'd take the detour...but if I'm going to a fishing spot or something, it's really nice to be able to jump on the highway for a few minutes and not be causing problems because I'm slower than traffic.

Sunday was a challenging trail (to say the least) and I did notice that 1st was now higher than I would have liked it. My clutch spoke up and said, "It's gettin' hot in here, I'm not working again until you give me a break..." This was a trail that , in hindsight, I had no business trying to drive ANYTHING through...but I was quite a way in, you weigh the options, and meh....chalk it up as a learning experience.
Last night was an average trail, no problems and was not wishing for a lower 1st gear.

So my experience so far, for my purposes, a 45 is working out nicely.

Can't blame Gary, back in the Olden Days when he started riding, a lot of bikes were 4 speeds.
I'll get you for that LT! :p Not only were they 4 speeds but also 2 cycle and any of the old 100 CC bikes could beat the pants off a 200 CC TW.

Gary and wife, back in the day...


LT back in the day...


:p
Well, Wish you were right about the first pic and that I still had the bike. Dead correct on the second pic and I was just getting ready to graduate HS and take off right after the Woodstock Festival. Never did like choppers but a 750 Norton Commando and a 750 H2 Kawasaki triple gave me all the thrills I needed. I got my dirt wheels on a Hodaka and then a Bultaco.

These stories are so funny :p
But by reading yeah seems that the 45 is the right thing for me since my city is pretty much flat with few hills, tho I drive alone so there is no problem power wise

As I requested few messages back (sorry to interrupt Your memoriesssss T_T)
I am sorry but I don't speak a single word of German haha
How do I order on that website?
If I order the rear sprocket let's say 45, the "package" will already include a new front sprocket 14 and a new chain?
Can You guide me a bit please? ^^'

Can't you translate the website page to English? If I remember right, I think you can on his site. You could also contact him at his website after translating your message to German. If you can, Sebastian is "more than helpful"!!

tw200 sprocket 45 in vendita | eBay

Usually there's a place that you can change the results to show the cheapest with shipping listed first. That's what I usually do.

Anyway... The description of the product will usually explain exactly what you get. I looked through a few in the search results and the picture represents what comes with that item. But, you'll have to read the descriptions yourself and make sure.
One kit I clicked on included a 14 tooth front, a 45 tooth rear, and a 118-link 428 chain. (428 is the 'family' of chain you'll need...you'll have to decide if you want HD, extra HD, o-ring, etc) the 428 is the family of chain, and the links will be a number like 118, 120, 122. Back to the kit with the 14/45 and 118 chain. I don't think a 118 will be long enough with a 14/45. I have a 14/45 and bought a 120, and it fit perfectly. From what I read on here, everyone going to a 14/45 used a 120-link chain.
So...read the description carefully.
14 or 15 will be the front sprocket size.
45, 47, 50, 55 will be the rear sprocket size.
428 is the 'family'..it will always be 428.
118, 120, 122 will be the length of chain. If you want to buy a chain that you don't have to break/cut a 120 should be perfect with a 14/45 combination.

If you're changing your front sprocket you'll need a side cover seal because you have to take the engine cover off the left side to get the sprocket. Have a look at the oil seals on the front sprocket shaft also...when the side cover's off would be a good time to change that oil seal on that shaft. TONS of chatter about that on the site...just poke around. Watch those wires! :)
