This is the low down from Ohlins:

The standard fitted spring rates are

Front mains 21-30 newtons or 120-171 lbs (270mm long)
Front secondaries 30 newtons or 171 lbs (60mm long)

Rear ( no secondary ) 62 newtons or 353 lbs (free length is 250mm)

Ohlins Spring recommendations, GNCC, for use with there revalving recommendations and Ohlins GNCC race kit KT772 which shortens the shock length (but maintains the shaft travel) lowering the quad.

FRONT, the springing is actually this&&&&&&&.stock main springs are as per ''medium'', but the smaller secondary springs are the light setting at 30 newtons. The ''medium'' secondaries are rated at 40 newtons. ( There is also a 35 newton option listed )

I noticed in the owner's manual that the stock springs are at the lowest preload allowed at the stock settings, is this accurate or can the preload be loosened on the stock shocks without any trouble? Just wondering since the stock shocks seem to be close for me. I didn't want to drop the money on the spring kit if I can lower the ride height now. If not, I'll go ahead and get the kit and revalve I guess.

be careful on the rear, you need a small amount of preload otherwise the spring floats around and hammers the preload ring, all goes bad after that.............

The shock kit shortens the shocks front and rear and drops the ride height. Try the stock front springs if you like them now.

Rear, the dual rate spring setup gives allot more progression than a single straight rate spring.

As soon as we get our springs i'll do a full article on the Ohlins kit and post it up here, unfortunately that won't be until 2nd week June (waiting on springs ex Sweden - we have these "problems" being at the bottom of the pacific on the far side of the world.... )

So you are saying that the stock front springs can have the preload loosened from the seventh groove without any trouble? I was looking to drop the ride height about 1/2".

Are you refering to the GNCC upgrade kit from Ohlins (the ad posted elsewhere on this site)? My shop contacted KTM and they said they never heard of it. Do you have to get it from Ohlins direct?
