    One issue with the final drive system of the Honda XR650L is the thin ( 8.5MM ) front sprocket quickly wearing the output shaft leading to break downs way out there or a very costly repair. Another is only one side of the teeth of the front sprocket can be used because the sprocket only fits on the counter-shaft one way.

    One way to reduce the wear on the output shaft is to use the wider ( 13.6MM ) front sprocket from a XR650R. Swaps like this usually result in a compromise. In this case, the compromise is the XR650R sprocket must be installed in reverse and this causes a difficult installations process and a misalignment of the chain. Some riders report that this misalignment is not a huge issue given replacing the chain and sprockets is easier than rebuilding the motor to replace the output shaft. But, the misalignment will increase the friction in the chain drive system thus wearing the chain and sprockets out more quickly. This is especially true for bikes used daily on highways for commuting. Most everybody agrees they prefer to have the reduced output shaft wear without the misalignment.

    A way to double the sprockets life would be to have a sprocket that fits on the shaft either way so both sides of the teeth can be used. Bear in mind you can't wear one side of the teeth all the way through, then flip the sprocket, and expect double life. You must reverse when a normal wear pattern develops.

    Now you can have minimum output shaft wear, minimum chain drive wear with the FRITZCOINC sprocket.

    The design of our sprockets provide correct chain alignment, allows for full spline contact with the XR650L's output shaft, fit the countershaft either way and straight up no hassle installation with the OEM two bolt retainer and fasteners. Our sprockets are machined from alloy steel that in every way is comparable to the best offered by other manufacturers. The sprockets are then given a heat treatment that provides a compatible sprocket for the Honda output shaft and longest chain wear life possible.

    This ad is for our 13, 14, 15, and 16 tooth sprockets.

    *NOTE, A 16 TOOTH SPROCKET IS THE BIGGEST FRONT SPROCKET THAT WILL RUN WITH THE STANDARD 110 LINK CHAIN AND 45 TOOTH REAR SPROCKET* THERE MAY BE SOME INTERFERENCE WITH THE OEM CHAIN GUARD.

    NEW 13 TOOTH
    This is an all new sprocket. Designed for OFF ROAD USE with the thought in mind that you can ride to your fav. off road spot ( say Houston to Big Bend ) using the 16 tooth sprocket and larger than stock rear sprocket ( say 48 tooth). Then quickly change to the 13 and enjoy the ripping torque provided by the huge amount of reduction the 13 tooth offers. The pitch diameter of the 13 tooth sprocket is too small to use the OEM bolt on retainer and a special very heavy duty spring clip retainer is included.


    We sell these sprockets on EBay. When in stock a link to my Ebay ad will appear below at " Order Here". Our Ebay ad will have current pricing and quantities available. All shipped free to the lower 48 states. We ship internationally and recommend the EBay international shipping option.

    Our warranty extends to the fit of the sprocket to a stock, unmodified 1993 to 2013 Honda XR650L's with the two bolt retainer. We are sorry but since we have no control over the environment this sprocket is to be used in wear is not covered by warranty. However, our sprockets are manufactured using the same processes as other manufacturers so the wear life of your sprocket will be the same or better than sprockets from other manufacturers.

    Fritz - I tried to order the 15T but the link does not have the order function like the 14T unless I'm missing something. The 16T does the same thing as the 15T link.

    I'm sorry and happy to report, I'm out of the 15 and 16 tooth sprockets.
    Still a couple of 14's left.
    The next order of sprockets is due Jan 8 2016.

    I'll tell you what Wattner, use your super XRL to shred test my sprockets!
    I'm confident there will be no issues till your beast wears them out.
    PS: need pics!!!!!!!!!!!
    PS 2: at this time, Pink is not an option.

    January the 8th! That's Elvis' birthday! I'm gonna get him a 15t for my XRL'ove machine.
    Can we place a back order Fritz? Pay up front ,mail em when they're ready type o thing?

    What are you guys recommending for a rear sprocket? I'm going to do both and a chain when these are ready. JT, Renthal, Pro-Taper, steel or alloy? Too many to choose from ,no data to support a decision....
    I haven't kept a Moto long enough to have to change em before.

    Steel of course last a long time, but aluminum reduces the un - sprung weight of the swing arm, are cheaper than steel, and last quite a while. An aluminum sprocket will last as long as most tires.
    There are a lot of Honda sprockets that fit the XRL. Some just need different bolts to mount to the XRL hub.
    One important thing to maximize the wear is to use sprockets as large as possible to attain the desired reduction ratio.
    Example: 14 x 45 = 3.21:1 reduction and so does 15 x 48 at 3.2:1.
    The chain will wear more slowly when making gentle bends around larger sprockets vs sharp bends around small sprockets.
    Another important thing to get the longest life possible is to use sprockets that work out to un even ratios.
    Example: 15 x 45 = 3:1 reduction, 15 x 48 = 3.2:1. What happens is that with an even ratio the same chain links contact the same sprocket teeth more often than they would with an un even ratio. Same deal with the gears in an automotive differential. And don't discount tire size. If you are using a taller tire like an 80 series, you will need more reduction to get the same reduction you had with a shorter tire.

    Brilliant. Thanks Fritz. Going to stick with the stock gearing ,been happy with it so far.
    Prolly going to change up the gearing once I get some street wheels dialed in though. The odd even aspect , never thought of it. Wonder how that sorts out on my single speed mountain bikes?
    As always thanks for the advice. Pete
    Did you ever get to those 606's I sent ya?

    A big "THANK YOU" for purchasing my product.
    I am currently sold out and expect more of each size Jan 8th.
    Please let me know how the sprockets work out for you. Your feed back is important for determining improvements that may be needed.


    Happy Holiday's everyone! ( even if you didn't buy one of my sprockets.

    Fritz...I bought one of your 14T CS sprockets for my XRL. Dumb question maybe...the OEM Honda sprocket keeper does not line up to install over your piece. Do I not need/use the keeper with yours or did I perchance get a bad part?

    I don't know what happened MUDHWY.
    I've sold close to 40 sprockets and have no other fit up issues.
    Got photo?
    If you cant post photos email it to me.
    Sorry and of course I will give you a full refund and send a shipping label for the return of the sprocket.
    Sorry
