B-Max 2 Kit springs - lb?

[Danosborne6661]

Had a look around a few different places but couldn't find the info, whats the rating of the kit front and rear blue springs on the B-max 2?

Yok havent published them anywhere, I think thats why everyone uses Associated plus the Yok range is limited. I still like the look of the Core spring kits.

Hmmm whats the next spring up and the next spring down from the standard Yok springs? From that we might be able to make a guestimate if people know what one stage lighter/harder is?

Rear yellow is softer than rear blue.

Front red is harder than front blue.


I use AE red or yellow front springs, and keep returning to the Yok kit blue XL springs, having tried all the lower rate AE BB rears... green, black, grey, white blue.

I'd love to understand the Yok BB spring rates. Looks like the BMAX 4III has different set of coloured springs, different versions of "soft", again not mentioning the soft ones on the Bmax2. Why is it so hard to get a published spring rate?

Even the Japanese team drivers seem to be using AE BB springs.

Ahhh ok, those grades don't seem to be covered in the Petit spring chart either. Can understand why people haven't been using the Yokomo springs now :P I'll take the springs off and compare them to some of my others to give a rough lb rating.

Here is a chart with the B-Max4 small and big bore spring rates. Maybe it helps a little at least.

I don't know why they dont release them as Id rather run the yok springs than the AE ones or others I have ran.

Whats "measured" on that chart?

I'm sure roger mills has a machine to check springs - maybe its worth asking him if he can and what it would entail etc?

AFAIK Arn0 measured the spring rates himself instead of sneaking into Yokomo's top secret database. That was back when he had access both to the necesssary device and the springs.
