Anyone have some .47-.50kg fork springs gathering dust?
Is that the stock rate...What is the stock rate?
Thats not stock, well above. Stock is .39kg, if my memory is correct.
I just put the .48 kg on my ride. $100 bucks at Race Tech. They do have them at the Thumpertalk store a little cheaper......
Great mod. since I'm tipping the scales at 265 lbs.
I think they increased the spring rate one year, but I don't remember which year it was... I have a 2000, and I THINK the stockers were .42, but I'm not actually sure...
I think Kevin knows the answer to all these questions; he posted a list once of all the little changes they made each year, from about '95 to present... That list should be made into a sticky...
According to the White Brothers suspension catalog (pg 104), '96 - '99 XR400 is 0.38 kg/mm and '00 - present is 0.41 kg/mm .
I was recommended to get the .52kg springs for my 400, to “balance the bike”. I guess that .52 springs will match the rear shock? I weigh 160, does that sound like the right spring for me? Any help would be great!
I was told 49-52KG, and I weigh 260, so someone has been told wrong.......... I got my info from the chart at 4strokes.com
I also weigh around 160, and I've found that around 8.5 - 9.0 kg/mm for the shock and 0.41 - 0.43 kg/mm for the fork seem to work well. Stock rates are shown above. Spring rate suggestions can be found here and here. Make sure you set your sag. I tend to prefer something in the range of 90 - 95 mm race sag on my '99 XR4.
I'm also interested if anybody has a set of fork springs collecting dust. Would like to find a set of the .41's from a '00 and newer.
Likewise...does anyone have a set of the stock 96-99 springs, 0.39 rate....that are still close to the original 510 mm free length? email me at email@example.com
As soon as I find some HD springs, mine '98s will be available!
