I just took my Super Duke to Traxxion Dynamics, in Woodstock, Georgia, for a suspension upgrade. I had them install AK-20s in my forks and an MC/10 Triple Adjustable JRi rear shock. I know others have already had the AK-20s installed, but I have the first Super Duke in the world with a JRi shock, or so I'm told! Traxxion sent the shock off to a powder coating shop that they use and the result was impressive! The local guy who powder coated my OEM spring did a poor job, so I was happy to get this one and have it turn out so nicely!

I arrived on a Thursday and dropped the bike off for installation. I was very impressed when they showed the shock to me. The finish was top notch. It also seemed much smaller in diameter than the OEM shock and was surprisingly light! The black, blue and Orange combo looked great, too!







I got a call later that day and was told that one of the eyebolts that came with the shock was the wrong size (12mm vs 14mm). I ended up staying in Atlanta to wait for the correct diameter eyebolt to be shipped. The new one was too long, so the technicians used the OEM eyebolt to measure from and machined it to the correct length. The installation went well after that. The shock would not fit with the reservoir on the right side, like the OEM shock, so it was mounted with the reservoir on the left. I don't think it makes a difference, but at least the reservoir won't be exposed to the heat of the exhaust pipe. The bike was then set up for me (preload, sag, compression and rebound).

When I picked the bike up, they told me that when they put the JRi shock on their dyno, they weren't happy with the results, so they spent about 2 hours re-valving it so that it performed to their specs. Also, when they handed me the OEM shock, I was surprised at just how heavy it was. It seemed twice as heavy as the JRi shock.

The Hyperco spring is smaller in diameter and provides for more space between it and the exhaust pipe.
Here is what the stock spring to exhaust pipe clearance looks like.

I'm really happy with Traxxion Dynamics and the work they did for me. They're perfectionists and it showed. If anyone else wants a set-up like this, I highly recommend using them. I wouldn't order directly from JRi without talking to the Traxxion folks first. If you go thru Traxxion, they'll have my specs to work from and should provide an uneventful experience.

I've had the bike out on a few rides and tried to find as many different situations as I could to test out the suspension, including some high speed runs. The suspension was flawless and was plush on bumpy surfaces and firm in the corners. The suspension no longer feels "wooden". It's more "responsive" now. A nice upgrade to the stock suspension!

Nice write up. Suspension is definitely next up on my list.

Looks great and wow that shock and a shit load of preload adjustment .

Size matters you know
