I am looking for a 63-70 tooth rear sprocket for my off road wheel.

Is there anyone who knows where I can find one?



Largest I can find is 58

Really? Will that even work? Isn't a stock sprocket a 50T ? Are you looking to be able to climb trees with the bike?

I think Ronnydog is your guy. He seems to be a real serious hunter and his TW is as well, a hunting tool. I think he went large on the rear and there is a vendor that can provide what you need. Gerry

All I can say is Yipes. Your top speed might end up being 35mph with that big a sprocket. I have a 54 I first bought to use in the soft woods and open fields. That was more than enough. Still had trouble climbing the steep track behind my house without a running start because the back wheel would start spinning near the top and I would come to a stop on the side of the hill anyway. I was used to my 4x4 climbing it with ease and I mistakenly thought the bike would do the same. It would be OK it the bike was All Wheel Drive. I now use a 52 as a good all-round sprocket. You can run 60 to 65 on the highway and still be able to run the woods if you want.

Sidewinder fabricates sprockets and can make one for you out of various stock (aluminum/steel/titanium). Search for them on the internet.

Hi Dave,



Do you use the original 14 in the front?

Did you change to an ORing chain?



Thanks

I am still using the 14 up front. I have settled on the 14/52 combination as the best all around for my kind of riding ( twisty country roads and even 1 or 2 miles on the Interstate) and I can still handle the dirt if I want to.



I did change to an O-Ring chain eventually. Very glad I did- the ride is so much better. A very worthwhile upgrade. I had my dealer order me an EK chain in a longer size for the 52 sprocket and I knocked off a couple of links to fit. It was so long ago I don't remember much about the details but I did post on the old forum. www.ekchain.com/or_select.htm And thanks to QWERTY for his rec- I won't ever go back to a non-Oring chain.

I've been thinking of switching my 54 for a 52, due to the massive wheel spin at the top of hill climbs...I changed everything (front, rear and chain) about 3,000 miles ago and have only adjusted the chain twice.



You think I can still make the switch without excessive wear occuring just from switching the rear sprocket??



I really don't want to change everything again.

Hi Adam,

I don't think you should have any problem as I did the same thing as I was fishing around for my ideal setup. Just take a look at the loading side of the front sprocket teeth. If everything looks normal without cupping you should be good to go. Chain condition also. Look for wear on the bars. You will just have to knock two bars off your chain and you will be on the road. I love my 52 but I don't think changing from 54 to 52 is going to help your wheel spin much. Going up a steep hill your weight is forward over the bars and front wheel and the back tire starts spinning because there is not enough weight on the rear. I have not been able to come up with a solution for this except to hit the hill faster so you maintain enough momentum to clear the last of the slope. There is always chains or spikes- but not very practical. I like the 52 as an all around choice. Good for woods-good for roads. Lots of punch up through the gears and it loves doing 50 to 60+mph.

I am running at a higher elevation and need a lot more power or gear. I have 2 rear wheels and 1 will have a bighorn soon, and I have several different sprocket and chain sets to play with but need more for the stuff I ride. I also want to lengthen the swing arm a couple inches. Also I am thinking a 400ex motor my be a close fit for the tw frame due to the fact the rear hub on a 4 wheeler is wider and may have a closer chance for sprocket alignment. Lots to play with on these, I think I better buy another one.

so for all you guys using the 52, what length chain did you end up using ??




Hi Mike,

The answer to your question is- it depends. All models have 14 tooth drive sprockets. 87 to 94 models have a 49 tooth rear and a 126 link chain. 95 to 99 have a 49 tooth 122link chain. 2000 to the present have a 50 tooth rear (USA) and a 122 link chain. I originally bought a 126 link chain for the 54 tooth sprocket and cut off two links when I went to the 52. The idea is to add the same number of links as the teeth you are adding.



Dave



This has been corrected since I originally missed the chain changes from 95 to 99. Apologies.

I did some checking on the speed calculator for the large sprockets. Running at 8000RPM your max speed with the 70 tooth would be 45MPH and 50MPH for the 63 tooth. FYI



Dave



I also think that is being optimistic. (I just found out what the green and red circles are for: just gave myself a minus 1--Hah!)

Hi Mike, DON'T REFER TO THIS POST.. IT HAS BEEN CORRECTED ABOVE

The answer to your question is- it depends. All the TWs have 122 link chains but the models from 87 to 99 have 49tooth rears. 2000 to 2010 have 50 tooth rear sprockets. Either way you are going to have to buy a 126 link #428 chain and cut it down. You want 124 links for the 50 tooth and 125 links for the 49 tooth since you are going up 3 and not 2 teeth up. Measure twice and cut once. The Gear teeth of the transmissions, the 14 tooth drive sprocket, and the 122 link chain seem the same for all years. The only difference would be the distance between the front drive and rear sprockets in the TW models. If this data is accurate, you should experience the same performance difference as the later model bikes, only it will be a bigger, more noticable difference for you since you are jumping up 3 teeth- not 2. Hope this helps.



Dave


Not really... But I do appreciate all the confusion you just cause me.. heehe. But I'm going from a 120 tooth on a 14/47 combo and I don't see anywhere in there about the 14/52 sprocket combo. What's worse, is that I think I want to go to the 55 the more I think about it..

Last year I put a 55t on my Mule and absolutely LOVE it. I do have the large Duro on the rear and the 55t gave me back the "spunkiness" of the bike. I can go 55mph and climb anything I want. When I switched I also put on an o-ring chain and have not even had adjust it yet! -Jeff

OK, Lets keep it simple: just add one link for every tooth you are adding to your present setup. I don't know how you ended up with only a 120 link chain. I was just looking at the Yamaha parts site and all the chains are showing 126 links. http://www.yamaha-motor.com/sport/parts/home.aspx My error on the early model chain length. I have to go back and correct my previous post. That does not explain your 120 links to the stock 126 links.
