Fork Spring Info
Spring Rate is the measurement of a springs strength.
Having the correct spring rate for the weight of you and your motorcycle is the foundation of good suspension. With weak springs the suspension will be too far down in it’s travel where it moves slow. You will most likely also have added too much pre-load on the weak spring so the bike jumps back up too fast after a bump.
There are three way I can fix this for you:
$110 for New Spring that my spring guy already makes. I have most of these in stock.
$175 for Custom Springs that my spring guy makes to order.
$75 if I shorten your spring to get a stronger rate.
A spring is just a piece of wire. If you shorten the wire it will take more load to bend it. Therefore, if I make a spring shorter it’s rate will increase.
This photo is of a set of stock ‘09 250 Ninja fork springs. The spring on the right shows the factory end. The spring on the left is the end that I cut.
Cutting springs is just a way to save you $35 and reduce my inventory requirements. If you don’t want cut springs, just let me know.
Fork Spring Spacers
When I need to make a different fork spring spacer I use PVC pipe because it’s inexpensive, easy to get, easy to cut, not effected by oil and is much stronger than it needs to be.
This picture shows a PVC spacer next to some stock plastic, aluminum and steel spacers.
The stock plastic spacer on the right has a wall thickness less than half the thickness of the PVC pipe.
I made this post because a few people over the years have been surprised when they found out about the PVC. If the idea of a PVC spacer drives you crazy just let me know and I’ll be happy to use something else.

Communication Skills
I’ve been working with Kenny and his Dad, Eric, for a few years now. Kenny is moving from Kart track bikes to full size track bikes and we have been up grading his suspension. We are also working on his communication skills as they apply to working with his crew chief.
On this test day at a top secret Kart track we did a little test after dialing in the bike and rider. I sent Kenny out for a few laps at a time with the settings mess up in a way that I knew what he would feel then listened to how he explained the feel of the bike.
It’s the job of the rider to tell the crew chief what he or she feels. It’s the job of the crew chief to understand what the rider is saying. To make this understanding come about a little work is required from both.
In this photo I’m making changes without Kenny knowing what they are. Then he will do 2 laps and report back.
The last test was the toughest one, I messed with the bikes balance. When Kenny was riding Eric asked what Kenny would feel and I answered. When Kenny came he said almost word for word what I said he would.
Now Kenny and I know we are speaking the same language.
Data systems were developed because crews could not get good info from most riders. When Kenny gets on a bike with data and what he says matches what the data says you can be sure his crew chief will be happy.
By the way, Kenny won his races the day after this test.

No, Thank you!
Ray sent me his 2002 BMW R1150RT-P shock for a rebuild and correct rate spring. This is what he had to say.
“Just wanted to let you know that I installed the shock on Saturday and had a chance to give it a road test. Well done! Works perfect and the bike rides like new.
Thanks for doing a great job.
Ray”
The stock spring rate is not strong enough for the bike an rider. With the correct spring rate you ride near the top of the travel where the suspension can move fast and deal with sharp bumps. This is what give the nice ride.
Enjoy your ride, Ray and Thank you!
