You can input all your variables there. Be sure to match the front and rear spring rates for best performance. Or you can also contact Factory Connection directly at 800-221-7560 for recommendations.

A: 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.

A: To give a more accurate recommendation I would need a little more information. Riding Type (MX, SX, Desert, Woods...), 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.

Assuming you are riding motocross, novice/C - intermediate/B skill, stock fuel tank, under 30 years old, under 6 foot 2, 160lbs. The best for spring rate recommendation I could give you would be .89Kg/mm Springs (Stock = .97kg/mm). You would also likely want to go to a 5.0Kg rear spring (Stock = 5.4Kg).

Q: Fork springs for supermoto?

Hello, I'm pai from malaysia. I've converted my kx250f 2011 to a supermoto. I need to lower d front. Do they come in shorter fork springs? Thx

A: Unfortunately shorter springs in the front forks will not lower your bike properly. The suspension would still be able to extend to its original length. The actual internals of the fork will need to be modified and you will need to send your suspension to a reputable suspension company to have this work performed. It is not advised to try and modify the forks on your own.
