Some info

Sommer-KTM (Europe's biggest KTM dealer) recommends these spring rates at www.sommer-ktm.de for the fork:

3.8 N/mm Ideal for light off-road rider weighting less than 55kg/123lbs
(Standard set-up in EXC 125/200)

4.0 N/mm For rider weighting less than 75kg/167lbs (EXC 250/300)

4.2 N/mm EXC 4 strokes, LC4 640 Enduro, SXC 625, SX 125

4.4 N/mm For SX with EXC model or for off-road rider over 95kg/211 lbs

4.6 N/mm For touring with bags, riding with passenger or for supermoto
(LC4 Adventure 640 2005, SM 625/640/660 2005)

4.8 N/mm Lot of luggage or Super Moto on streets (950, Rallye Replica 660)

5.0 N/mm Super Moto Sport (SM 640 2002/2003, SMC 660 2003)

I went for 4.8, but I can't comment how they work. Springs have just arrived and are not yet installed.

About the shock they say:

50/260 For light or small rider.
56/260 LC4 1993-
60/260 Competition 1994
63/260 SXC 635 2005
66/260 LC4 Enduro 2005
70/260 Supermoto 2005, Adventure 640 1997-2005
75/260 Rallye Dakar, Supermoto 2004
80/260 Lot of luggage.

At the back I still have the original 70/260. I may change that later, but I am not sure.
