Sprocket Size

25 posts in this topic

I was wondering what the biggest size rear sprocket you can install with the stock chain.I have the stock 48 tooth rear and I think i would like to go to a 52 tooth sprocket..

Checking the chain stretch ,according to the manual my chain has no measurable stretch,and the sprockets now show no wear to speak of,only a 1000 miles maybe of use.

I went with 13/50 on the stock chain. If you go with a 13 up front and leave the 48 on it would be like a 14/51. One tooth down on the front is like 3 up on the rear.

you want to keep an eye on the chain guide and swingarm rub plates with the different sprockets...quite possibly they will wear out much faster with the chain rubbing more ...

That was one of my concerns,the chain guide & slider..

I wonder if a 50 tooth would make much differnce in gearing and not cause excessive wear of the chain guide :cry:

This is a question I am wondering about as well. I find myself needing to be in between 1st and 2nd when riding tight trails and rarely getting into 5th. I'm looking for advice on how much change would be needed to make a difference. I would like to be able to stick with the stock chain as well. JC

I went to a 14/51 ratio last year. I dropped it down to a 14/50 this year. The 14/51 was mint for riding. However, I have an Xr's only chain guard and slider and it chewed them up good. Also it through off my chain adjustment. I had to cut a chain to size and then had to leave my chain blocks extended further than I wanted to until I could take another link out of the chain. So it made my bike feel like it was really long in the turns. I went to a 14/50 and like it so far. No real difference.

Timbrp,do ya feel that the 50 tooth made the gearing lower....

I ride tite trails and wanted to slow it down a little more going down steep hills:excuseme:

13/50 is great and I have been running it for a year now. That is the lowest you can go without cutting the stock chain. If it wears the slider on the swingarm or guide more it is not all that much and the sliders can be bought for around $50 (OEM) or so. Do it you will love it.

By the way the bike will still do 80 mph or so with the 13/50. That's plenty fast for the terrain I ride.:cry:

Definitely. Just get a good chain and two steel sprockets at 14,50. You'll be happy you did it. You can just put it in 3rd(drive) and go. Lugging up hills and then nail it and she'll be right there. :cry:

I went with the 13/48 combo and it worked great in the tight stuff. A lot less shifting and a lot less stalling. I rarely touched the clutch. 3rd gear and go.

I could also then switch to 14/45 for riding in Mexico with the same chain.:cry:

:cry:

I put a 13 on the front of mine and left the rear alone. Same as jack attack said...Less shifting and alot less stalls. Works great for where I ride

That's what I was looking for. I don't need to go a fast as the stock gearing will go. I also want to be able to lug for real big hills. Riding in the mountains in Oregon the stock gearing seems to high. Thanks

I ran 13/50 and loved it!

On some different trails that were faster I thought I'd change the front b/c its quick and easy but I couldn't fit 14/50 on stock chain. So I had to remove the rear wheel and put my 48 back on.

When i gear down next time I think I will just change just the front sproket and ride with 13/48 to see how that works b/c it can be changed real quick without removal of the rear wheel, just adjusting the tension of the chain!

(Front sprockets are cheap too compaired to rear)

I have no unusual wear on slider due to my past 13/50.

We'll see how 13/48 does!

i'd suggest try a 13 front first and if you want more add 50 rear b/c going 1 size down in front is more of a change than 2 up in the rear! 14/50 wouldn't be enough for our woods.

My opinion

Go 15/47 and hold onto your shorts. 100 m.p.h + easily. Almost shat myself last weekend in the washes at Ocatillo. A buddy clocked his bike at 94 m.p.h on his GPS and I was pulling away from him pretty quick. GPR stabalizer on "6" setting and hold the f**k on! :cry: :cry: :cry: :cry: :cry::devil:

I like the stock 14/48 for tight stuff + limited dual sporting. I am already looking for 6th gear on the road. Taller gearing in the woods helps mellow out the low end and keep in controllable. Timbrp, maybe if we manage to hook up this spring, I can try yours and be convinced otherwise.

With the 13 tooth front , Is that harder on the the slider???
It is definately harder on the slider. It will take a long time to wear though. Took me close to 3000 gnarly miles.

You really have to look close to find where it is wearing. Get on your hands and knees and look under the very front of the swingarm.

When my slider wore out I just bought another from Service Honda , no big deal.

:cry:
