Very springy

I rebuilt my rear shock and filled with 12 psi of nitrous. My 96 yz resto was done besides the suspension. After replacing this spring it was like riding a new bike, had to get used to it but once I did it was so much better. Just remember it can be dangerous adding a stiff spring on your rear end without doing the same to your fronts. Thanks!

Perfect sag (2013 ktm 300XC)

Purchased this about a month ago (6.4kg). I'm 6'1" and weigh 245. This has been fantastic for my trail riding. Bike corners and rides over obstacles much more uniformly. I would recommend factory connection springs.

Great Difference

I bought this about a month ago and have put about 60 miles of single track on it. It has improved my speed trememdously as I do not have to worry about my back end washing out. I would recommend this to everyone

Super boingy thing!

The paint is fantastic! I like this thing, but it did take me a few hours to straighten it out. It was all coiled up like a garden hose in the box when it arrived at my door. Once I got it straight, I was abe to install it in my Van.

A: To help us to find parts to fit correctly, we will need to know the year, make, and model of your motorcycle.

When it comes to recommending suspension parts and settings, there are too many variables, such as rider's weight, road and track conditions, riding style, passengers and luggage, for us to make a well informed suggestion - other than what the motorcycle-manufacturer recommended from the start as OEM.
A couple of excellent resources are Factory Connection and GP Suspension! They examine you and your bike and consider your unique requirements.

A: Reach out to Factory connection for recommendations on spring rate based on your weight and riding style. I would recommend shaving your existing seat or buying a shorter one over attempting to reduce seat height by suspension means.
