Hey guys, I did some searching for 15t sprockets, but can't seem to find much online. Bikebandit and Motorcyclesuperstore don't seem to have them, is there another place where I could check? Thanks!

Spudrider posted this good info awhile back ( http://tw200forum.co...2/ShowPost.aspx )



"In the interest of helping other riders, I have compiled the following information regarding the availability of countershaft sprockets for the Yamaha TW200 motorcycle. To the best of my knowledge, countershaft sprockets for the TW200 are available from six different manufacturers. If I have made any errors, or omitted any important information, please do correct me.



PBI is a company located in Oregon. They manufacture the following countershaft sprockets that fit the Yamaha TW200:

12-tooth sprocket, part #50-733-12

13-tooth sprocket, part #50-733-13

14-tooth sprocket, part #50-733-14

15-tooth sprocket, part #50-733-15 out of stock 5-2011



I have also seen reports of a 16-tooth sprocket, part #50-733-16. However, this sprocket might not be currently manufactured.



All PBI sprockets should be able to use the Yamaha sprocket bolts and retaining clip without modification.



Parts Unlimited also markets countershaft sprockets for the Yamaha TW200:

13-tooth sprocket, part #K22-2601B

14-tooth sprocket, part # K22-2675

15-tooth sprocket, part # K22-2601C



It has been reported that the Parts Unlimited sprockets require larger bolts, and larger holes must be drilled in the sprocket retaining clip.



JT Sprockets produces one model that fits the TW200:

14-tooth sprocket, part #JTF 1559.14



Sprocket Specialists produces two models that fit the TW200:

14-tooth sprocket, part #566-14

15-tooth sprocket, part #566-15



Be careful to select the correct year of manufacture for your motorcycle when ordering these sprockets. It has been reported by some TW200 owners that these sprockets are a very tight fit on the countershaft.



SunStar Sprockets makes one model that fits the Yamaha TW200:

14-tooth sprocket, part #21314



Finally, Yamaha also markets a sprocket for the TW200:

14-tooth sprocket, part #93823-14149-00



Thank you to all of the previous posters on this forum who have provided me with this information."

These people have the 15 tooth in stock. Call Amanda.


Yeah, they had it. I was told shipping would be $10-15 dollars. I complained about such a high shipping fee for a part you could put in an envelope. Was told it would probably be near the lower end. They don't give real shipping price when you order (only phone orders allowed). Ended up costing $16.xx to ship a $21.xx part. I will not buy from them again.

Oh Man!! How cheap are you? If $16 is going to break your balls to ship a piece of solid metal though the postal system then I think you should sell the bike and walk. It's not about the price of the part, it's about the wieght! If I where them, I wouldn't sell to you or anyone in your family again you tightwad. You will be running out of places to buy if you buy many parts for your bike at that rate.

I live in Hawaii and am extremely cheap.... and very observant of shipping prices. $16 is more than it should cost to mail a front sprocket given you can pretty easily fit it in one of those USPS flat rate envelopes for less. But almost nobody ships anything for exactly what it cost to send,there will pretty much always be some sort of handling fees. I'm kinda confused on the fluctuating price though? Did you just give them your credit card # and cross your fingers? If so that's just asking for trouble.... from one tight wad to another




Also you should call and calmly explain your problem with there estimate and maybe they will refund the dollar or so to make it right by you and or find a way to give definitive shipping prices.

The thing about calling them over the phone is that long distance costs money too! It will only add to your expense! Just install the sprocket and ride! Move on and enjoy life.

The company I work for ships all it's products, nothing is 'walk in'. Sprocket Specialists is a 'small' hole in the wall operation and likey does not enough shipping volumn to get much of a rate discount from UPS.. We get asked/told all the time to simply put it in a bubble pac and ship first class. Great idea, HOWEVER; if there is a glitch, and it is not all that uncommon, the customer will be on the phone asking you where their product is and all you can say is, "I put it in a bubble pac with the address you gave me". How well do you think that will fly? It doesn't, you end up shipping a "no charge" replacement, likely with a greater (to vendor) shipping cost so at least now it can be tracked. I know, currently the options with the U.S. postal service have been expanded to afford tracking (more $$). Then the issue is, you have already negotiated a contract price with U.P.S. based on volume you expect to ship, and you have a 'system' in place based on your shipper.



I just shipped B-dub rack from my work-place. The rack is a little over 10 pounds (unless some part of it was resting on a stack of papers next to the scale). Our contracted price (huge volume) was $7.59 from Chico, Ca. to Utah.



I know, it seems $15 is high, but no-one stays in business long makeing a habit of 'screwing' the customer. Sprocket Specialists have been around for a while so I expect that charge reflects their time and expense in getting that sprocket to you. My thoughts anyway. Gerry

USPS Priority Mail Small Falt Rate Envelope with Delivery Confirmation is $5.65 anywhere in the U. S. of A., and the envelope is free for the asking. Even cheaper when going through PayPal. $16 to ship a sprocket is a decided lack of customer service. Sprocket Specialists is a manufacturer, not a retailer. Many retailers sell their products, and wouldn't if SS delivered parts cheaper than reatailers could. Think about that for a while and you'll figure out SS knows which side of their bread is buttered.



That said, I'm not too keen on SS wheel sprockets because they don't fit TWs and the necessary high-strength hardware to make them fit isn't available locally. I suppose that's olay if you can get the correct hardware where you are--there is some advantage in lower unsprang mass with the relieved centers.

Order 15T Sunstar here.



Any local shop who buys from Parts Unlimited (practically all independents do) can order the Parts Unlimited 15T countershaft sprocket for you.

aaaargh!



Now I'm really ticked.



Good find




By the way, if you buy this to save money on gas, think about it. If you get another 5mpg over 95, you are saving about 17.5 cents per gallon (@$3.50gal). At an optimistic 100mpg that would be $1.75 for 1000 miles, $17.50 for 10,000 miles, about 12,500 miles to pay off.

(22,000 for the one I bought)




Only works if you need a new gear that is replacing a worn out gear.

Usually a noise/vibration/engine wear concerns is the reasoning behind raising the gearing. Some do it for top speed but find it only helps if you are going downhill... mileage though... I'm starting to think I'm not that much of a tight wad after all lol

Hi very useful thread. Do you have any suggestions about what to do when you extend the swing arm? I understand there will be a bit more pressure because of the leverage. Is it advisable to use a heavier spring?

Any advice greatly appreciated

Cheers

Al

What about a 47 tooth rear?

14/47 is 3.357:1 ratio. 15/50 is 3.333:1 ratio. One would be hard pressed to tell the difference.

14 and 47 have no common factor greater than 1. 15 and 50 have 5 as a common factor. Greater the common factor, faster the chain wears. Smaller the common factor, more likely minor damage to the chain will be burnished out before damage to sprockets occur. Probably more than counteracted by the lower wear rate of bigger sprockets, with each tooth of a 15/50 set seeing only 93% of the usage as a 14/47 set for the same miles ridden. Both are popular mods with the same general effect.
