That's about right for your weight.

Have you had the shock revalved? At that weight, you need more compression damping... turn the 17mm adjuster in.

I don’t disagree, but I also don’t agree here. Just saying to turn in the high speed might not be the only thing he needs. We really need more info like his ability, what’s the sag set to, what are the current clicker settings, how much pressure are the forks set to? Personally when a track gets rough I open the high speed about a 1/4 to a 1/2 turn and it helps a ton. I’ve also seen that with faster riders KTM’s with the stock clicker settings like to pack the rear suspension so speeding up the rebound would help hold the bike up better.

Thanks for the feed back.. I’m not to advanced on bike set up to be honest, but I was just wondering am I too heavy for the spring that’s in the rear shock, and could this be causing my front forks to feel stiff because compared to my buddies bike it doesn’t feel nice to ride at all.. also I have the rear spring tightened a lot witch mightened be helping the feel of the bike and why I taught spring might not be the right one for my weight ☺️

There is no way for us to help you without knowing what your race sag and static sag is. With those numbers you can determine if your rear spring rate is correct. Use a zip tie to determine the front. MXA is your friend search their website. The answers are there

Anyone 230lbs running a 54 spring needs a shock revalve. Clickers is just a temp fix

None of the information will be helpful until you tell us what year/model bike you have? 2020, 2015? 125/150, 250f, 450?

54-260 was the stock spring on 250s before 2016

Also, for a wp 54 260 spring, adjust it to 253mm with 7mm preload, this should give you 105mm sag. This is how you know you have the correct spring rate.

Harsh forks on these bikes is often not enough compression damping on the shock.

5.4 is for around 180lbs on that bike. 5.7 for roughly 200

Rider weight without gear *

Blimey, 54 spring works for 230lbs on the 2016 newer setup and I assumed that's what we were talking about.

2015, I don't have a clue, ignore all I've written above.

On 2015 chassi you need to be at 60-62nm rear spring.

54nm was stock on 2015 250 i guess, i know 57nm was stock on 450.

Yes, you are correct about the rates. I couldn't remember which model I just knew the 54s were stock on something

Op, I'm about your weight and I checked the Race Tech Spring Calculator (Google will bring it up) for my bike, stuck that shock spring on, set the sag and set the clickers to the 'sport' / stiffer settings from the manual for a temp fix until I had the suspension re-valved. I'm sure the calculator isn't perfect and I know this is a band-aid temp fix, but it was fine for me personally being slow and just out for fun.

Bleed the excess air out of your forks too if you haven't, my mate hadn't done his all the time he had his bike and there was a fair hiss out of them haha. Weirdly, same principle but with ghetto parts, my nephew's pit bike the forks go wayyy hard if not bled every couple of rides.

This spring thing sure seems complicated to figure out which spring is correct .

What spring is this?

4cs forks? If so, ooof. Those aren’t helping anything either.
