IKON Shocks

[geoff in almonte]

Hey All

I am looking to replace the OEM Sachs units on my CalVin.

MGCYCLE lists the IKON 7610-1607 for $400USD with medium duty springs 235-22/30/39.

Anyone using these shocks/springs?  Should I go for the heavier springs 235-26/34/43?
What do these numbers represent?  The 235 is the spring length (in MM), but the others?

The bike (08 CalVin) is used 50/50 for touring (one up with gear) and moderately aggressive backroad scratching.  Sometimes both at the same time.
Rider & gear (helmet/jacket/boots) weigh in around 220lbs.

The OEM Sachs bottom out remarkably easy (even under max preload) causing a head shake at mildly aggressive cornering speeds and an alarming wallow as the pace increases.  The Gazis that were on the bike when purchased do the same.  The front end (Matris) was fully serviced and dialed in at John Sharrard's shop (Accelerated Technologies) and he pointed to the rear suspension as the culprit. 

Thanx

My son and I replaced a pair of shocks on a V50 with Ikons from MG cycle and have been very happy with them.

We had the opposite problem (used bike).  With my 250++ lbs on the V50 there was no sag on the lowest setting so the bike would beat you into submission on rides.  I think the previous owner that changed the shocks out used Chinese shocks for a Harley.

We haven't been able to put enough miles on the new shocks to speak to a 8 hour ride.  The bevel box is over at Harper's getting a new case and rebuild.  yes Luigi didn't torque the shoulder bolts correctly 35 years ago

Unless you're really big, regularly ride two-up, or are carrying heavy loads the standard springs work great. They are a bit more controlled than the Sachs original. They seem stiffer, yet they respond to bumps/potholes in a very smooth manner. If you'd really like a treat, install a set of aftermarket fork springs and change your fork oil out at the same time you replace the shocks...

Agreed.

I have two bikes with Ikons on them. They perform quite well, are adjustable for preload and rebound damping and are rebuildable.
