Title: ITC shock springs
Post by: bigk on October 05, 2016, 06:27:36 pm: I've heard that yellow ITC springs are a heavier rate than white ITC springs, can anyone confirm or dispel this please?
Cheers,

Post by: 80-85 husky on October 05, 2016, 07:27:14 pm: hey mick, ive heard from plenty that they are heaps better. no idea if they are heavier. the word is they don't sit as much as the white ones, have a bit more spring. (suggests a heavier initial rate)

Post by: b490 on October 05, 2016, 08:14:16 pm: Have the yellow pair on my 83 XC 500 .
Feel firmer than the white ones on my '83 250 & have slightly larger diameter coil as well.
Got them here ; (spring rate listed on link)

Correct Mick. The 9mm dia wire 16 coil is the stiffest ITC direct replacement at 10% stiffer. The white springs are 8.5mm 16.5 coils

Post by: bigk on October 06, 2016, 11:03:00 am: So the plot thickens. I have 2 pairs of yellow ITC springs here (untouched originals), both are 8.5mm wire thickness with the same amount of coils as the white sets I have. Interesting to say the least. I also have a set of non progressively wound springs with 8.0 wire thickness, 13 coils. These are supposedly a heavier rating but I really am uncertain. Walters springs are a good price, I'll do some testing with what I have but it looks like I may be giving him a call.

The 9mm progressive ITC springs have code 00180-40 L4813.

13 coil will be stiffer than 16 coil of same wire size.

Post by: b490 on October 06, 2016, 09:22:10 pm: As fitted to my XC500
Ohlins P/N: 00180-40 L3210 9mm dia wire

Looks to be 16 coil ;
