    yes, but it's my "fun time playing" with the throttle. I was getting about 37-39 mpg before. I reset the computer and the latest stat was 31 mpg and climbing. Once the new acceleration and power band thrills wear off I'm sure I'll get back up to 36+, but I'll let you know. It also keeps me from drifting up into the 90s on the highway. I'm tending to cruise at ~78 at 5k rpm.

    Riot - thank you. Worked on it today and these instructions were spot on. Notice they even put in an alignment dot to make it idiot proof when putting it back on. Thanks!

    If you look at the Spec for the DID 525VM2, it is rated for just over 8,000lb of tensile strength with a maximum of 750cc recommended ( no doubt for off road use and likely 900cc for on road). I also don't think the chain represents the best value for your money considering the cost. Perhaps consider the GB525XSO-124 by RK with 8,850 lbs for just over a buck or JT JTC525X1R124L with 8,930 lbs of tensile strength for right around 65 sheckles shipped. Just my two cents :eek:))

    Why do you need to order/use a new bolt kit for the rear sprocket and what is your source for this?

    You do realize that you are replying to thread that over two years old.

    I realize that threads often get revived and that people still read older threads and may want more "current" input. Thank you for your concern though.

    The rear sprocket bolts tend to get messed up when you remove them. Not all of them but one or two is enough that you need new ones. On all my dirtbikes, I replace the bolts. I haven't done my rear on the Tiger but I'm sure they sell a sprocket bolt kit.

    I'm about to do this job on my Tiger at about 14k miles. starting to see some rust coming out from between the links on one or two of the pins. So I want to replace the whole shebang before it becomes an issue. The process seems pretty clear, I just want to make sure I have all the parts I need before I start the job. The one thing that seems unclear is do you need to replace the nuts and/or bolts from the rear sprocket when you change that? Just wondering if anybody has done the job yet and if they needed to replace the parts.

    The nuts are of a locking type and should be replaced when you renew the rear sprocket, according to the service manual. That said, I neglected to order new nuts when I renewed my sprocket and reused the old ones. 10K+ miles with no issues. YMMV.

    I realize this is an old thread - But I'm considering going down to 15T on front sprocket, my riding style is typically using 6000+ RPM and I don't like super slabbing at 4-5K RPM. I go too fast anyways, 90 MPH max is all I really need, there is a front wheel wobble anyway in 100 MPH with all the panniers. But getting to that speed faster is certainly something I look forward to.
    Also on off-road/dirt the 1st seems too tall, and I'd love to have better acceleration and less clutch feathering in slow speeds.

    The MPG is probably going to be hurt a bit, but that is OK, I have 2 extra gallons (Rally Raid Rear Gas tank) and fuel price is not a concern.

    Can anyone actually riding with a 15T FS setup provide more details and share his experiences? Pluses and minuses with real life usage.

    TIA.

    Hey BM, when to a 15t FS at my first service, so I simply don't have facts and data to speak to the MPG hit.

    However, I have a steeper then normal drive way to my house. And here in the PNW it can get a little slick with pin needles and moss.
    On the day I road the new Tiger home, I noticed that first was way too tall. My old HD and the Goldwing I own have a much lower 1st gear and thus are much more controllable at low speed inclines.

    For me the 15t FS made a very noticeable improvement and I am very pleased with the resulting low speed throttle control and maneuverability.


    As part of the purchase price, I negotiated the cost of the 1st service, and a set of new Heidenau K60s. When I made the appointment I asked them to order the 15tFS and add it to bill. It's not a ton of cash and they needed to remove the rear tire, however, it was still nice the dealership gave me the part for free and my total bill out the door was still zero (Savage Cycle, Victoria).

    My riding is mixed highway and backroads on a still to be broken in XCx, given that, I have not seen any real MPG hit.

    The 15t Fs does present issues at red lights when the bike is in rider mode with the sport map and with TC off. That darn front K60 sure seems alot lighter then stock!! :)

    I have had the 15 on for some time. I never think I'll go back to 16. In fact , have a week long trip in Colorado on the books and might drop a 14 on for that occasion. I love the better power earlier , and did it so when I'm off road , it would develop power more like I was used to on my dirt bikes.

    Somewhere on here I posted that while riding with another 800 in stock gearing , there was only a 300 rpm difference at 80 mph. Not enough to sweat. Fuel mileage was negligible as well. Do it , if you hate it , you have 30 bucks and an hour of time in it. But if you ride a lot off road , you'll love not slipping the clutch so much due to that tall first gear.

    Thanks for your input.
    Seems to me like a feature not a bug or issue! :D
    Seriously, in the dirt I'd love to be able to lift the front wheel sometimes when hitting a rut. The default Tiger XCx setup is too oriented to road IMO.
    It would great if Triumph (edit: better) differentiated the XC family from the XR, and perhaps the 15T should be one of those differences.

    Great feedback, thanks!

    @Black Rhino
    Regarding the installation process of the FS:
    1. I understand that I need a 36mm socket. Will this work? http://www.amazon.com/gp/product/B000NPUKJ8
    2. I read somewhere here that the gear has to be in N and that the rear brake needs to be engaged when the FS is removed.
    Does that mean that first the FS is removed *with thenchain* still on, and only after that the rear wheel and the chain are are removed?
    That is - Can the 36mm socket access the FS nut with chain still on the FS?

    I don't remember the size (but I had the socket already) , 36 sounds right. It will fit with the chain on , which yes , you need on to break loose. I just had my better half stand on the rear pedal and it broke fairly easy. Loosen the chain enough so that you can remove the front sprocket. Take off the old one , slide the new one on , slap the chain on and tighten down the nut. Then adjust the chain. I had my wife hold the pedal down both on and off. Easiest solution.

    Thanks again.
    When I do the swap I plan to properly document it and will post the photos for other inmates to follow

    Nice sprocket site, added to favorites. 19,000 miles and going strong.

    Just installed the 15 - test ride tomorrow. Followed the step by step on page one of this post - thx to Riot. I did find the conversion listed - 85nm = 93 ft lbs to be incorrect on my torque wrench and a few conversion sites I checked. 85 nm is equal to 62 ft lbs / lb ft. I had success loosening and installing/torqueing the CS nut by applying the brake from one side of the bike and leaning over to do the work. Look forward to the better off road control.

    Report back: Do it.

    Much better off the line, more control in the dirt. It just made the shift points feel like it should for a dualsport/ADV bike. No clutching on mild/moderate uphill dirt road corners, just back off, roll on. My RPM's only went up 250-300 at 70 MPH.

    Appreciate all the install guidance - very helpful!
