Default Suspension HELL YA !

The MT Bag shock from DNM (in Taiwan) is a HUGE upgrade. It was pricey (in line with a Bitubo shock) but is adjustable in preload, compression, and rebound damping), with a remote reservoir. Also, I had to order it direct from DNM, essentially transacted completely by email, and had about a three week lead time.

As noted elsewhere, the rear suspension has been the missing link for me on these bikes. Being able to put all the pieces together has transformed the bike, and I am rapidly regaining long forgotten skills.

The pieces of the puzzle:
Sava MC50 tires
AF1 front spring kit / pre-load adjusters
DNM MT-Bag rear shock
Brembo front master cylinder
Stainless brake lines
Motul RBF brake fluid
NG brake rotors
Ferodo pads

Not an inexpensive journey, but WELL worth it.

Only thing missing now is the ability to easily adjust rebound damping on the front suspension

Good info. Especially the suspension as I am trending to "robust" as well. Glad we have another source of info to go with AF1's forum!

Default Suspension ... yup.

The suspension was really the final bit to getting the RS50 to be a satisfactory ride.
Adding the spring kit made a BIG difference, but also pointed out how crappy the rear shock was.
The DNM shock was not inexpensive, it was on par with the Bitubo shocks that are kind of the de facto upgrade path.

I'll be buying a second one for the silver bike this spring.

Add the brake upgrades, and great tires, all in all, it's become a very fun ride.

Next upgrades - I'm looking for some GOOD rearsets, and considering going to GP shift, to better facilitate a quick shifter setup. Yeah, Yeah, I know... don't really NEED a quickshifter, etcetc. However, I'm interested in ways to keep the RPMs up during upshifts, as I find that even my best shifting allows the Rs to drop 1000 -1500 RPM, enough to drop below the powerband on the kit I'm currently running.
