Tuning noob; order of buisness...

What do you weigh roughly?  Apart from the beetle map being a priority, having your forks and rear shock modified for your weight was a big and beneficial change for the better.  Once you start to get around 90-95kg and above some major handling/rideability gains to be made relatively cheaply if you use the stock forks and shocks.  A suspension guy will customize your spring weights, rebound and compression valves, shims and oil weight. Also have a Schraeder valve tapped into the reservoir if you are going to keep it. Plenty of threads on the options.  

I did not know enough to do it then but doing it now would take the forks and rear shock off myself and then ship them to someone well regarded (and reasonably priced).  The GRiSO has rebound, compression and preload adjustment on forks and rear shock so no need to go aftermarket - just needs tweaks on the internals. Ghezzi seems to be the suspension expert.

The Norge is much more basic with minimal adjustment on the forks so I went Matris front and rear for under a thousand USD total from Carpimoto in Italy.

Thanks for the info - sounds interesting; I must be somewhere around the 80kg mark but I've read some really good (non Guzzi) articles on the advantages of having the suspension honed to suit rider weight/riding style so well worth a look into...

Be careful with rear Matris 'honed' to suit your weight and riding style....to be fair to Biketorque UK, they are sorting it out with the italian factory (after the Italian 6 weeks holiday season), but two of us with very different weights and similar riding style expectations went for Matris & both got exactly the same units - and both were much stiffer spring rate than stock (I'm 76kg), which wasn't the direction we were hoping.

I also had a Matris installed (second best decision ever, Beetl map first) and the secret is go to a suspension guru. They will take a look at you, your weight and ask what type of riding you want to do then install a spring to suit. Bespoked Matris is the best shock i have ever had, and that is saying something after riding many Dukes with Ohlins!

My Matris shock is definitely not oversprung.

I think my Matris is double sprung or at least it should be to haul my corpulent mass.
