Brake Pads
Stark Varg uses Brembo calipers with DOT 5.1 fluid - NEVER use DOT 3 or DOT 4. Galfer is the confirmed OEM brake supplier for Stark Varg (Galfer/Stark partnership 2023). Sintered Double H = HH compound for high-performance motorcycle braking. IMPORTANT: Stark OEM front pads (custom Brembo/Toyo compound) reportedly outlast aftermarket options - consider OEM pads for front and Galfer for rear.

Brake Pads
Brembo hydraulic system uses DOT 5.1 brake fluid — NOT mineral oil. Mineral oil will destroy Brembo seals. OEM part number SMX1-BR-FW-04. EBC MXS sintered pads are a known aftermarket alternative — verify fitment with caliper model.

Brake Pads
OEM part number SMX1-BR-RWF-04. Rear pads are different from front — 220mm rotor vs 260mm front. Same DOT 5.1 fluid requirement. Do not substitute mineral oil.

Brake Fluid
Stark Varg uses Brembo brakes requiring DOT 5.1 fluid — NOT mineral oil. This is the OPPOSITE of Sur-Ron and Talaria (which use mineral oil). Using mineral oil in Brembo calipers will destroy seals. DOT 4 is compatible in an emergency but DOT 5.1 is preferred for high-performance use.

Galfer also fits KTM, Husqvarna, and GasGas enduro/MX models (NOT KTM Freeride E-XC — that uses DF796W). Thicker at 3.2mm vs. bicycle DB-series rotors. Wave design reduces weight and operating temperature.

Chain
Top-of-line 520 pitch X-ring sealed chain. DID positions this as their do-it-all off-road rally chain. X-ring seals provide 15% longer lifespan vs. non-ring. Available in shorter link lengths (110-120L) than the ERT3, so verify availability for your specific link count requirement. For riders who prioritize chain longevity over cost, this is the premium upgrade from the non-sealed ERT3.

Chain
For DID 520 ERVT X-ring chain. Two connecting link variants: press-fit clip (CL) or rivet (RL).

Recommended for KTM Freeride E-XC, Stark Varg, Sur-Ron Storm Bee, and Segway Xaber-300 running the 520 ERVT chain.
