Magnesium swingarm respring question

[twowheelcossack]

Howdy all, I'm about to install a magnesium swingarm 20mm longer than stock and am wondering how to respring it for a 210 pound fella like myself. I'll be using the progressive setting on the rocker. C'mon Molasses, I'm looking at you on this one...

Changes take place -you will need to replace the spring with a stiffer spring (around 8%-12% stiffer).

Stupid question - I presume you've got the whole kit (new arm and all ...?)

Yeah, I got the whole kit: swingarm, eccentric, rocker and all titanium fasteners including custom made ti swingarm pivot axle and shock/pushrod bolts and nuts (sweet...). That's precisely what I needed was a percentage of increase for the spring rate due to the longer swinger. So 10% increase in spring rate would be a good place to start Neil?

Hey I was just going through the whole thing. the ducshop does real good work. They are going through redoing my Ohlins. They also have real nice offset triples to use with the swingarm. call mark

You are the man........I wanted one for so long on my 996s, but chose to trade it in for a 999r. Although I love my new r, I still wish I kept the 996. So I envy you lol.

The mag swing arm is so expensive, is it REALLY worth the money?

I am looking for technical information to help me set up my suspension for my weight and configuration. Please don't highjack my thread; stick to the question or start your own.
