What's up guys.YurFatMom what would be the right rear shock spring rating for my 02 kx if I weigh 230 lbs?I'm seein on the tech site it has 165-180 lbs is a 5.3 rating heavy.i was lookin at the kx 500 ratings and for 175 + its a 5.7.And for a kdx 220 its a 5.4 for 200+lbs and says extra heavy spring.Are these in the same ballpark or is it all different for just the kx?.I was just curious cuz I am right much heavier than 180 lbs.Any help would be appreciated dude thanks!

The reason these springs are for other bikes are heavier than your KX250, but yet are set up for lighter people, is because of the different leverage ratios on the rear suspension, valving, the weight of the bike, ect. Follow the Race Tech site's recommendations.

-If you change the rear shock spring, the fork springs must be replaced to match the new rear spring. Otherwise the bike will be unbalanced and it will handle like a green p.o.s.

You need the balance between the front and rear, for the bike to turn, take hits, and track in a straight line properly, not just for jumps.

Then you got taken to the cleaners! You can have the front and rear suspension both revalved and resprung for like $600-$700 at Pro Action.
