Spiegler Performance Parts • Hand-Assembled in Dayton, Ohio, USA
Spiegler Stainless Steel Rear Brake Line – 1-Line Original Routing
Fits Kawasaki GPz1100 1983-1984
Firm lever. Confident stops. Zero guesswork. Spiegler lines replace soft, aging rubber hoses with a precision-built, DOT- and TÜV-approved system engineered for riders who demand more from every squeeze of the lever and every press of the pedal.
Factory rubber hoses swell under pressure, and that swelling is what you feel as a spongy, inconsistent lever. Spiegler eliminates it. Every line pairs a low-expansion DuPont PTFE (Teflon) core with a tight-weave stainless steel braid, then finishes it with aircraft-grade stainless steel fittings and Spiegler’s own patented Torsion Fitting System. The result is crisp, repeatable feel and modulation you can trust, from the daily commute to the last lap of a track day.
Note Regarding Shipping: Brake lines cannot be shipped FedEx and will arrive separately from other items ordered!
What Sets Spiegler Apart
Patented Torsion Fitting System
Spiegler banjo fittings rotate up to 180° or 360° even after assembly. No twisted lines, no fighting the hose into position. Just align the fittings stress-free and route the line cleanly, without damaging the hose.
DuPont PTFE (Teflon) Inner Lining
A low-expansion DuPont PTFE core sits inside a tight-weave stainless steel braid. Unlike rubber hoses or inferior braided lines, it resists swelling under pressure, keeping your brake lever, pedal, or clutch lever firm and responsive.
Tough UV-Resistant PVC Outer Coating
A protective PVC sheath covers the braid, keeping dirt and road grit from wearing down the line and stopping the metal braid from scratching your paint, fork tubes, or bodywork.
Aircraft-Grade Stainless Steel Fittings
No cheap carbon steel or low-grade hardware that corrodes or fails over time. Spiegler fittings are built from aircraft-grade stainless steel for strength and long-term durability.
Certified Street Legal: DOT & TÜV
Every kit is DOT-compliant (FMVSS 106) and TÜV approved, meeting rigorous independent laboratory testing standards that many competing brands, some labeled “race use only,” don’t.
Race-Proven Rennsport Option
For track and specialized builds, Spiegler’s Rennsport kits run a single line from the master cylinder to a T-fitting, then down to each caliper, avoiding the clutter and clearance issues of stacked dual banjo bolts at the master cylinder. Rennsport kits are sold separately; see the product title for this kit’s configuration.
