Factory connection puts great finishes on their rear springs

Dover, De
Great!

I bought this shock spring along with fork springs about a month that ago and I love that I did. I didn't know what size to get so I called factory connection and they told me what I should get for my height and weight. Fter riding a few times I'm noticing I can get on the throttle earlier and harder than before going through corners. Jumping is much smoother and scrubbing is easier as well. Definitely the best purchase I've ever made for my bike.

Awesome

Can't beat it for the price. In my opinion having properly set up suspension is the first upgrade any rider should do.

Perfect. Unless your the perfect size for your bike, you'll need a spring. Factory connection is the bomb. Thanks Motosport.

I bought this shock spring along with new fork springs for my bike and man what a differnce! The stock spring was so soft that I was always using the entire stroke and I don't ride on a track with this bike. This spring made the bike jump more predictable and flat. It doesn't blow through the stroke and gave me a lot of adjustment that I can use now. We'll worth the money! I wish I wouldn't have waited and done this sooner.

How does this fit to your mounts to wear it bolts into your swing arm and frame?

A: The shock spanner nuts need to be loosened and then the shock will need to be removed from the bike. Once removed you will be able to remove the spring keeper and slid the spring off the shock. I recommend you get a service manual to follow.

A: You can find a few online spring generators to help you determine the correct spring rates for you. Here are 2 links to follow:
http://www.racetech.com/
http://www.mx-tech.com/
You can input all your variables there. Be sure to match the front and rear spring rates for best performance. 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.
Or you can also contact Factory Connection directly at 800-221-7560

A: I'm also a 260lb rider. I installed a 6.3 spring in my 2009 crf 450r and it worked great for me. Most riders say it to stiff but of corse most rider are under 200lbs. I hit jumps with confidence knowing that the spring will not bottom out.

Q: Are these compatible with a full Pro-Action suspension setup?
2 years 10 months ago
Previous owner had a full Pro-Action setup installed. I also planned on purchasing the Factory Connection fork springs. Will these, and the fork springs fit? Or do I have to buy Pro-Action springs. If so, would you be able to tell me where I can purchase them online?

A: Yes the Factory Connection Springs would fit the stock shock and forks on your 2006 Yamaha YZ125. Pro-Action likely re-valved and sprung the stock suspension. Just be sure to correctly select the Year/Make/Model of your bike before ordering so we can be sure to send you the correct springs for your bike. Also, feel free to give us a call at 888-676-8853 and we would be happy to help you out with your order.
