Needed to increase my fork spring weight and decided to go with theses rather than OEM. Worked great, however you may need some extra spacers to reach the proper preload, as the springs can vary in length.
I had been riding on the stock springs on my 2007 CRF250 for way to long and it was time for a change. As a larger rider, I went with the .49. Installation was a breeze and the springs feel great. The front end no longer feels mushy, I highly recommend!
My son is growing and our KX85 was suffering. These springs along with a matching rear spring made a night and day difference in the handling of the bike. We got another year on the 85 allowing him to grow a little more before he gets on a 125 or 250f.
Best thing for your bike if you are over 6 feet tall & over 200 lbs. Call & give them your hieght, weight, & type for riding. & they will recommend spring rate.
Can't get over the difference. Feels like a new bike, a lot more fun.
"Getting the correct suspension for your bike is a MUST!!! I am about 210lbs and I was riding with a stock spring weighted for 135lbs and it made such a difference; It provided a more smooth ride and more comfortable ride. This product is definitely worth the money! The best part is, finding the right rated spring is made really easy with the help of Motosports's customer service!"

if the bike is sprung for ur wieght its gonna handle better,mabye without a revalve.it has for me,i paid 115bucks for mine its pricey but i do the work myself so having a bike that handles well and doing my own work i can easily justify the cost
To give a more accurate recommendation I would need a little more information. Riding Type (MX, SX, Desert, Woods, Trail/Enduro, Etc.), Skill Level/Racing Class (Beginner/D, Novice/C, Intermediate/B, Expert/Pro/A), Gas Tank Size (stock or oversized) as well as Age, Height and Weight all factor into proper suspension set up.
With the information given (assuming your riding motocross with a stock size fuel tank) the closest recommendation I could give you would be a .47Kg/mm fork spring (Stock = .45Kg/mm).
The OEM fork spring rate for your 2012 Honda CRF450X would be .47 KG. Base on the information you have given my recommendation would be a .52 KG fork spring.
If you do go with stiffer spings in the front forks I would also recommend going with a stiffer rear spring as well. The OEM rear spring rate for your bike is 5.5 KG. Based on your specifications the recommended rate would be a 6.1 or 6.3 KG Shock Spring
Suspension set up can be very technical. This information is base on a generic spring rate recommendation chart I have. I also would recommend checking with Factory Connection directly on the suggested rates for your bike and size as they may have more accurate recommendations for you.

Kinda depends on the bike and what terrain your running, is more wet woodsy off-road or desert soft dry. you will get a little different performance depending on the bike weight, and if your in soft dusty vs the hard pack.

I like hair scrambles and especially any type of hill climb. I run a KX500. Shocks suck...I bottom out easy and the bike is not plush. I only weigh 160lbs. My oil is being changed right now and may help? Ideas?

im 5'9 and do motocross what sppring rate do i need and also i wrecked and ever since like when i put pressure on my suspenion my forks rebound but i can pull it up another inch if i hold the front brake and lift the bike sits up higher but it doesnt do that on its own it only comes up half way thanks and also im about 195lb and ride a 2004 yz125
The suspension should sag slightly under the bikes own weight. That is not going to be an issue. If it is only about one inch that would be about right for the forks. At your weight for your 2004 yz125 the front fork springs should be a .45. The rear shock spring should be a 5.0. When installing the springs it would be a good idea to break the forks down and check the bushings also. You will be able to see if there is any abnormal wear from a possible bent fork tube. It is not very common to bend a fork tube but it is possible. The other possibility would be if the front end was twisted during the wreck but that would be alleviated by removing the forks and reinstalling them.
The Shock is elementary but you will need your owners or maint. manual for the springs, its not hard (less work than replacing fork seals) but requires partial disassembly of the fork and you need to replace the fork oil.
