2008 EC300 for small rider
 

Am about to purchase a new 2008 EC300
I am 60kgs and about 159cm (5'3") tall
Could i please have some advice on getting the seat height down and also what rate springs i would need for my weight.
I will chop the seat also - as i mainly ride standing (trials rider and habbit from riding older bikes)

I would not suggest butchering the seat. A better alternitive might be having the suspension professionly lowered since you be needing springs anyhow?, different rear dogbones are also available for lowering the rear end.My friend who is 5'5 had his new ktm 450 lowered one and a half inches. I rode it and I dont feel it has been compromised in any way, he does'nt mx though. As a added bonus the lower cg really helps that thing rail the turns. On a gasser with a featherweight rider it would be a amazing weapon.

You are much shorter than myself at 6'0".

Here is what I would start with - the inexpensive route...

Set you rear loaded sag at 120 to 130 mm. The rear suspension works well with this much sag, assuming you have a reasonable spring rate.

Raise the forks in the triple clamps up to the point where the front tire just clears the front fender when bottomed.

Cut the seat foam down. Worst case you buy another seat foam.

If that doesn't get you close, then it is on to the suspension mods to lower ride height - like the longer dogbone links.

Cutting the seat foam may be a problem. The fuel cell forces the seat to be very thin forward of the top sub-frame mount. I would go with Widebear's suggestion. Lower the suspension. I have ridden seveal lowered bikes that impress me with how well the suspension works even when 2 inches of travel is taken away. The only disadvantage I see is ground clearance, which is why my bikes are stock height.

Good luck in your set up!

When I give my 6 year old son a ride (he weighs 100+ lbs geared up to ride) his added weight compresses the suspension/tires about an extra inch. I ride with my toes up and my feet hit way more stuff along the trail as result of the lowered ride height. My feet get shoved off the pegs far more frequently. 2 inches lower would be even worse.
