Upgrading Fork Springs

Good evening everyone. I will be taking my beloved to the shop for many new parts and upgrades, and I call upon the great and wise for some advice. On fixing my forks I want to upgrade the fork springs and asking what is best and why? Racetech or Traxxion or another brand, but why. I will be ordering according to my weight, 290lbs.... I will be installing a 2016 rear shock outback for the time being to see how I like that upgrade. I've been out of the loop on suspension parts for to long, and I don't want to be snookered by the shop.

Thanks for any all help as always

David

I would call Traxxion & RaceTech to see what they recommend. I've used Traxxion for several Yamaha bikes & will be using their springs next season on my '19A.

Either one is fine. They do not make the springs. They source them from a manufacturer so they might be identical. Race tech, Traxxon, GP, Penske, whatever. You most likely need a 1.1. Do not get a progressive spring. They are junk. The softer section is too soft and will just compress to the heavier weight. So the progressive section is useless.

You are wasting your money with a 2016 rear shock unless you get it free. I may be slightly better than the '05 especially an worn out one but a 290lbs it will be woefully under sprung for you. Save you $$$$ on the '16 shock and get a aftermarket MADE for your weight.

The Traxxion kit is the easiest, it comes with all you need and the spacers are precut... basically a plug and play deal. Most likely they will give you a 1.1 spring rate, and you can always add preload if you need to.

It is a bit less expensive, and I think for an extra $20 you can get the plastic spring guides which are a nice touch.
Other kits require you to calculate the spacer length and cut the spacers, and if they supply plastic spring guides, they cost like $50 extra.

You can change the spring. More then likely the old shock is blown. Depending on your riding ability and your sensitivity to suspension, the newer shock paired with the correct spring will do wonders.

It's simple math.

There are lots of good components out there. Traxxion is a good suspension shop but pricey. I used GP springs and valves when I redid my forks and they came out great. Most anything you do will be a big improvement over stock.

"Unless you get it free"



So he buys a 3rd gen shock for what $200?

Then a spring for $120?

Then pays a shop to change the spring $60.

So he has $400 into crappy shock with minimal adjustment. Which will work fine for some riders.

Or double that to $800 for a high quality highly adjustable custom built for his size and riding style.




The FJR is not a beginner bike. Its not a bike bought by kids with finance problems.

We spend thousands of dollars on gear. Several sets for different seasons.

We spend thousands of dollars upgrading lights, seats, windshields, foot pegs, crash bars, luggage, coms, navigation, exhaust, tuning,



Yet we penny pinch when it comes to the single most important aspect of the bike. Suspension.

Like I said, it depends on the rider and what they demand of their suspension. If the rider logs 5000/year that $400 will last 4-5 years or even more if ridden gently. If that rider is a flatlander, has never upgraded their suspension and thinks it's adequate, then $400 makes sense. I agree with you that the suspension on the FJR, like most Jap bikes, is inadequate but everyone has different expectations and it's easy to spend someone else's money.

I agree.

I put more emphases on suspension priority over other items on the bike.
