    Need advice on 06 KTM 250 XCW front and rear springs?

    KTM suggested a .48 front spring rate, and a 9.6 rear spring rate. 9.6 seems a bit stiff in real world riding, so I am going to install a 9.4 and see where that takes me.

    need advice on 2006 KTM 250 XCW front and rear springs please!

    Oldman, All, My front feels OK at .48, a little hard, but liveable. Others told me that I need to go to .46 instead....that .46 is what I need for my weight and less aggressive riding. I may change to .46 in the future. But my real issue is that my rider sag was more (146mm) than my WP owners manual said it should be, but the ride is harder than I like. The 146mm rider sag (vesus WP owner's manual target rider sag of 90-105mm) would tell me that the 9.6 shock was TOO soft. But the ride with it installed is TOO hard...even with compression and rebound adjusted as best and they can be. So I am getting the reverse of what I thought I would get....that's what has me worried. So my question is which of these do I do: 1) use 8.9 or 9.0 spring, instead of 9.6? (8.9/9.0 calculated by using the forum formula of bike weight + rider weight /divided by 55.8 = correct spring rate for rear spring (240+260=500/55.8=8.96 spring rate) 2) use the KTM suggested 9.6 spring rate (currently in, can't get rider sag that manual says to get, and rear end rides too hard for my tastes even after adjusted) 3) use the Racetech calculated PDS P30 spring, that was their recommendation....and they recommended .46 in front as well (versus current/KTM recommendation of .48) 4) Any other ideas/suggestions/advice?? thanks guys! Jason
  3. Hoping you guys can help me with this! Looking for some front and rear spring advice. Bought a used bike, 2006 KTM 250 XC-W. Bike is a mish-mash of parts/Franken-bike, so no clue what springs are in the forks or on the rear shock (no markings, no factory numbers, nada!) Front forks are obviously from an SX model (not hte XC-W model) as they have both adjustments on top (plastic rebound knob, plus preload nut) Rear shock is also from and SX, as it has both low and high speed adjustment on the top of the shock. It has also obviously had a bladder kit installed at one time, as it has a schrader valve on the bottom of the resevoir.... Fronts forks are of course are open chamber, and rear shock is of course the non-linkage, PDS swingarm shock. I am 240 lbs without gear, 260 lbs with gear, 6'1". KTM dealer said go with .48's in the front, and 9.6 in the rear, even though my calculations said 8.9 rear and .46 front KTM dealer said don't worry, I can return both if they don't work. OK cool! I installed what they suggested, and the front feels a bit hard, and the rear also feels very hard. I set the static sag at 35mm, with 12mm preload on the spring, and then climbed aboard. Rider sag was 146mm (should have been 100mm or so) Put a tiny bit more preload on the spring (1 turn), then got a rider sag of 126mm. Tried this setting, and the rear still seems harsh. Set my compression, rebound, etc. per factory spec, and spent about a 1/2 day dialing it in as best as I could get it. Verdict? Still too hard for my riding style. So does this mean that the 9.6 rate rear spring is just too hard? When I add bike (240 lbs) plus rider (260lbs) and divide by 55.8 (formula I got off Thumpertalk to calculate the correct rate), I get an 8.96 rate. Should I ask them to order me .46 fronts and 9.0 rear? Do you think that will be closer to what I need based on my weight? I like my suspension a bit on the "cushy side".... fyi, I called racetech and they said use their .46 fronts and their PDS P30 rear...anyone have that setup and weigh what I weigh? Most reading on the online forums say racetech usually recommends too stiff a spring. So maybe I should try a PDS P25 instead? Thanks for any help or advice! Jason
