I tried the 14/47 sprocket combo for about 100 miles. The lower revs were nice on the level, but any hill required a downshift and I ended up going slower up the hill, my gas mileage dropped from 77mpg to 73, and trail riding suffered. I ended up going back to the stock 14/50. Has anyone else been disappointed with taller gearing?

I have never tried the 14/47 but there have been reports in the past of people trying it and coming to the same conclusion that you did. Then they returned to the stock ratio.



Some people like the 14/47, but you are definitely not the first to come the conclusion that Yamaha's stock ratio makes sense (unless you want to gear down for an off-road advantage).

I liked the 14/47 so much I changed out my wife's dub and my riding buddies dub... We all like it better......... Our gas mileage stayed 78/85.. We ride 90% on hard pack or paved roads............ We rode them out west in the bad lands and south in tenn. and the gearing worked just fine...... OMM.

I have a 15 tooth front and stock rear and am fairly happy for longer runs, but I agree the off road capabilities do suffer a little. Pretty flat here in most areas but I could see where taller gearing would be annoying in some hilly areas. I was wondering about mileage, mine seems to have suffered some also, I just went to an oring chain not that long ago so I wondered if it was the chain some too?

I like the 14/47 for street riding and the 14/55 for offroad. A dual sprocket setup allows the best of both worlds with minimal hassle to switch back and forth.







Just insert or remove a small chain segment.

I had the 14/47 when I bought the bike. Did not like it at all for offroad riding. Now I've gone to 14/52 and love it. Now I can ride the dirt roads/trails in 3rd and 4th instead of 2nd and 3rd. LOVE the 14/52

WOW THATS FREAKIN" SWEET! how did you do that did you just bolt it on with a spacer in between? how do you switch sprockets?

I like the taller gears, im currently running 14/47 and i like it but i want to go a little higher for the street and probably do a 15/47, and it still wont suffer that bad offroad (I know this because my buddy has it) but if I can have the best of both worlds I'll totally go that way if its not a huge hassle.





Also got another quick question..., How does that back tire do on the road at high speeds, I want one but I'm not sure how it will do on the road. Thanks

I like the 14/47-15/50 best for all around riding. To me its the best compromise. It has taken me everywhere that the 14/50 has. I do like the 14/50 gearing better for serious off roading. I ran the 15/47 for a 1600 mile road trip and that is the max i would go. Anything higher it probably wouldnt pull it very well and im only 150lbs. I did take the 50 rear with me incase i didnt like it. One nice thing was that on roads like the blue ridge parkway going uphill at higher elevation you could run 4th at 55-60mph no problem. 4th feels just a tad lower than 5th with stock gearing. On our way back home we were in a hurry and took I-75 for almost 400 miles at 65-72mph. I was glad to have the 15/47 then. Its fine for gravel and dirt roading and it will get me most places off road but you lose alot of bottom end.

Dako,



Here's the dual sprocket thread.



http://tw200forum.com/index.php?/topic/641-the-dual-sprocket-thread/



To change sprockets: lift the rear wheel, loosen the rear axle, either add or remove segment of chain depending on which sprocket you want, readjust chain and retighten axle.



Before I got the 55 tooth sprocket, I was running a 47/50 rear combo. This was nice because I could use the stock length chain for either sprocket - no need to break the chain to add or remove length.



The Duro feels a little gravelly when you first start off, but once you get going it smooths out and you don't notice it. It has a pretty square profile and likes to go straight ahead, so it takes a little more effort to initiate turns. It handles fine up to 65-70, but that's about the limit for my TW.

Thats awesome thanks for the info, Brian. Im probably gonna do the dual sprockets! Do you think if I did 47/52 combo in the back I wouldnt have to change the length of the chain every time I switch though?

As for the tire Im still not sure... Is it DOT approved?

i tried the biggest hills here on guam and the 14/50 was just enought to get up in fifth gear without a passenger. so if i had a pass i would have to down shift already with 14/50. my top speed her is 50mph anyways. no need for more speed here. i am getting best of 90mpg now so im good with 14/50.

I am not sure if you will have sufficient adjustment range on the rear axle for that spread. Where are your snail adjusters using the stock 50 tooth sprocket? If you are somewhere around midrange, it might work. If you are significantly less than midrange, you probably won't be able to move the rear axle forward far enough for the chain to work on the 52 tooth sprocket. If you are planning to replace your chain, you could try one link longer and it might be enough to make it work.



If you decide to use an ATV tire, they are significantly taller than the stock tire so you will have less clearance in the crotch of the swingarm and will lose some of your rear axle adjustment range. In that case your 47/52 would probably not work.



Unfortunately the Duro is not DOT approved.

I, too, was disappointed with 14/47. It's what came on my bike, and I ran it until it was toast, then swapped to 14/50.



My observations were pretty similar, but I think part of my problem was with the way the bike was running lean. Now that I've got that mostly sorted out, I think 14/47 wouldn't bother me as much. I did notice my bike was geared plenty higher than my brother's TW (14/50) offroad. My first gear just didn't have the same grunt as his.



On the pavement, his seemed to have more ability to actually maintain speed with 14/50 as well. I took the cue, and am sticking with 14/50 (or lower!) for the next set, too.

What sort of top speeds do you 50 toother guys achieve and how rung out is the engine up there?



I wanted to be able to go 55mph and actually leave town, but even with a 47 tooth sprocket, 45mph seems to be the upper limits of what I'm comfortable abusing an engine at all day in terms of RPM.



I CAN go nearly 70 mph with 47 teeth, but the bike feels like it's telling me to stop beating it.



Meanwhile I read posts where people claim to ride these bikes loaded up, across the desert at 75mph. I don't even get how that's possible.

I don't think there is a sprocket combo which would make everybody happy. There is simply too much variation in the way we use the bikes, the terrain, and our personal expectations.



If I was going to load up my TW like a pack mule and hit some very rugged trails, I'd opt for the 14-50 in a heartbeat. Lots of weight, high center of gravity and a lot of rocks and ledges means the slowest possible speeds.



That is not the type of riding I do, though. I do occasionally get into that type of terrain, but I don't do multi-day off-road trips, so I don't have to load my bike down. I can carry everything I need for day trips in my Dirt-Bagz, which don't compromise the bike at all. A big rack on the back for me would just add weight and get in the way. They do look cool, though.



The biggest attraction to the TW for me was the license plate. I have been riding dirt for more than 50 years and usually on bikes which were off-road only. Locally, my favorite riding area is about 35 miles away. There is a nice twisty two lane highway which goes there, so it is kinda fun, even on the pavement. Not with the 14-50, though. I cringe when I hear an engine screaming at high speed when it is unnecessary. The 14-50 on the highway feels to me the same as if I were running my 5 speed truck locked in 3rd gear.



Of course with the 14-50 you seldom need to gear down for hills on the highway. You are ALREADY geared down.
To me the effort required to drop one gear is not even a consideration, and 4th gear with a 15-47 is very close to top gear with a 14-50. The tranny works great, and with a small engine, that is what it is for.



To me, an even more important reason for higher gearing for the highway is the fact that cars and trucks tend to run much faster downhill than uphill. Any straightaway is going to have the 4 wheelers trying to go 65-75mph plus. If you are in front of them they will ride your bumper trying to pass, and when they do pass they often barely clear your bike. Not fun, and with a 14-50 trying to match their speed is abusing the engine.



As for off-road, since I don't carry much of a load, I'm free to ride at any speed which is comfortable. Even off-road I spend a lot of time in 2nd and 3rd gear, and reserve 1st for the really gnarly stuff. Even at altitudes of 8000 feet in the Sierras I have never felt the need for a lower gear than 1st with a 15-47.



So, my point is that everybody should figure out what works best for them, considering where they ride, what kind of terrain, how much they carry, and what speed they need to maintain to keep up with traffic.



What we really need is a TW with a 6 speed tranny and 14-50 gearing. The 6th gear would drop the revs to the equivalent of 15-47.



As it is, one size definitely does not fit all.

I'm new to this bike, so take what I say with a grain of salt. I didn't like the stock set up since I'm riding it only on the roads at this point. When I get her to Vermont, I'm planning on a lot of back dirt road riding, but still roads. I went with the 15 tooth up front and it's made a big difference with speeds around 45 to 50 MPH....the engine just seems to be in it's happy zone a bit more. Granted, on a few uphills I find that I need to downshift from 5th to 4th....but overall I prefer this setup.

I feel like my bike can actually get to and maintain a slightly higher (comfortable, not *top*) speed with 14-50 than I felt comfortable with on 14-47 sprockets. Yes, it does wind a little higher into the RPMs, but I think my all-time highest speed on my TW was 64mph, indicated by my trailtech vapor. My 'average' top speed is about 57mph, and we have lots of hills, which loses me a lot of speed either way. Let me be clear: I haven't, and don't wish to ever hit the top speed on this bike.
