Matris M4R for sale, this is the top of the line damper made by Matris. Really well made piece, along with the mounting kit for a GSXR 750 SRAD. Different mounting kits can be used with the damper. I would also assume that it can be used in certain OEM damper locations.
Looking for $350, cost new was insane.
Titanium body with a titanium nitrided rod, for real low stiction. Real smooth action with heaps of adjustment.
Manufacturers blurb:
Titanium external cylinder.
Twin tube system with Al 7075 Aluminium alloy coaxial internal cylinder with oxidation treatment.
High tensile alloy steel piston rod with hard chrome coating, lapped finished for an effectively “zero” stiction and PVD TIN (Titanium Nitride) surface treatment. Single rod system supported by oilless slide bearings.
Stainless steel screws.
External tank for controlled heat compensation of fluid expansion, pressurized with Nitogen gas (N2) for greater stability at high operating temperatures.
Hydraulic brake adjustment ring nut with calibrated holes (16 positions).
“Speed Sensitive” progressive hydraulic damping system.
Aluminium alloy front rod-end with chromium-plated Steel/PTFE/Bronze wheel.
Comes with the original box and all the instructions needed.
Pic is a bit shoddy, tomorrow in the sunlight I'll get some better ones.
