    Plug in your bike details, you can play with the numbers till speed/rpm is where you want it. If you'll be riding long distances (thousand of KM) I'd run a 15 tooth front and figure out what size rear gave the speed/power you want. The 15t cs will last longer and be better for the chain and rear sprocket over a long distance than a 14t.

    Thank you again for the beta.

    Edit: I never looked at that website before, pretty interesting info on there for sure. I think I’ll run that 49 and carry a few fronts to change it up as needed. On my 640 I can handle 3 different sizes at least with no chain adjustment.

    One of these days I will find a suitable trail for my 525.

    A friend sold me his plated 2005 EXC450 RFS today, mint condition and only 6000 miles. A factory edition so a black frame and machined triple clamps. He gave me an additional 13L KTM tank too. It's my 3rd 450 RFS in 10 years! I keep coming back to these bikes! :D

    Do you know what has been done to the motor? Valves, Piston ?

    Nice looking bike, good luck.

    Sounds like the primary nut may have backed off. Easy fix and it happens sometimes to RFS motors. Dave hopkins sells a hardened nut for this.

    Thanks! Yes, I have the full service history since the bike had 1500 miles. First valves at 290hrs but they are in spec.

    Bad news.
    It was amateur hour at my shop last night...

    I was doing some upgrades to my 525’s clutch (while it was laying on its side) and when I using the impact wrench on the clutch basket center nut, the shock load knocked a bunch of the tubular drive sleeves EVERYWHERE. Some went on the floor, some got lodged in little exterior nooks and crannies of the engine, and ONE decided to go section 8 and jump down inside the transmission sump area. When it happened it was like mice or rats scattering...every which way but loose!

    Good news!
    I stuck a telescopic magnet down the hole about 6” and swirled it around for a few seconds. I then slowly pulled it up, and wouldn’t you know it, the final missing drive sleeve was stuck to the end of it! I’m getting my bike prepped for the LAB2V ride this thanksgiving, and when that drive sleeve fell down in there, my heart sank quite a bit. I think it’s time for me to buy a lotto ticket.

    Lucky enough that I think everyone here should go buy a lottery ticket tomorrow.

    Happy winnings everyone!

    heh, the other fun ones are those little bushings on the shift forks.
    Get everything together, start putting stuff on the case halves, click through gears only to find things are feeling sloppy... shake the cases a bit and hear the rattle of something metal in there... :baldy
    fish around with the magnet and pull out one or two of those goddamned bushings....

    Guys, I need a little bit of advice. I've had a couple of the RFS bikes, a 525 and a 450, and both were outstanding. I've also run the gamut of the other usual suspects- WRR, DRZ, XRR, KLR. My most recent stable includes an R1150gs and a '13 KTM 250xc. I'm selling the KTM tomorrow and plan to replace it with another lightweight dual sport (we've moved somewhere with less hard core off road riding but way more forest service roads/ jeep trails).

    As far as I can tell, I can get into a low hours RFS 525 for around $3-$3.5k (when they show up). A 500 is going to run $5500+, and often the hours on the bikes in that price range are pretty high. For the kind of riding I will be doing, I don't think I really need the improvements of the 500, and I could build a killer 525 and still be in it for less $$.

    So, what do you think? low hour 525 for thousands less, or will the new ones be that much better?

    If I found a low hour 525 for $3-3.5k, I'd buy it in an instant. Should not have sold mine. I have no experience with the 500, though.

    Personally, the differences in weight and handling aren't enough for me to worry about. I am way beyond racing or tackling the gnarliest of trails just to prove I can ride them. I have aged into a true dual sport guy.

    So, I would go with the low hour 525 right up until parts start to become an issue or unless I rode at altitudes where EFI becomes important.

    I also like being able to do a valve adjustment in minutes rather than hours. If I went with a 500, and no doubt I will at some point, I would likely pay a shop to do valve adjustments. I never have liked fiddling with shims.
