The ProTaper Contour 1-1/8-inch Handlebar is the most popular oversize unbraced handlebar in motocross, engineered to deliver exceptional durability and controlled flex at an accessible price point. Replacing weak 7/8-inch stock bars that bend in tip-overs, the Contour features aerospace-spec 2000-series T6 aluminum alloy with an engineered 5mm wall thickness at the clamping area that tapers gracefully to 7/8 inches at the control ends. By eliminating the crossbar, the Contour allows the aluminum structure to flex naturally, isolating the rider's upper body from repetitive micro-shocks.
The Contour's surface is treated with chemical profiling and hard-anodized shot peening, creating an exterior barrier that resists scratching, corrosion, and metal fatigue. When navigating rough tracks or rocky trails, the Contour provides a plush yet connected feel. It eliminates the harsh, jarring feedback typical of stiff OEM bars, helping riders maintain looser grip pressure and stave off premature forearm fatigue. The right-side control area is chemically polished to guarantee zero-friction throttle tube operation, while the left end features deep knurling to anchor the clutch grip.

### Step-by-Step Installation & Safety Protocols Installing the ProTaper Contour requires 1-1/8-inch bar mounts. Disassemble all handlebar-mounted hardware, noting the routing of the throttle cables, front brake hydraulic line, and wiring harnesses. Place the Contour into the lower bar clamps. Use the centering grid to dial in your preferred tilt angle, then torque the clamp bolts evenly in an alternating pattern to 20-24 Nm (15-18 ft-lbs). Mount the controls, ensuring adequate lever reach and ensuring that the front brake master cylinder sits level when the bike is upright. Verify that cables do not bind when the handlebars are turned lock-to-lock in both directions.
### Maintenance & Durability Lifespan Maintenance consists of routine post-wash inspections for signs of deep gouges or impact stress around the clamping areas. Clean with standard wash solutions and dry thoroughly. If the motorcycle sustains a severe impact that bends the bar, replace it immediately to maintain rider safety.
Frequently Asked Questions
Q: Is the high-density molded bar pad included with the Contour?
A: Yes, every ProTaper Contour handlebar comes complete with a high-density molded foam bar pad and a durable vinyl cover with Velcro closure.
Q: Can I install the Contour on a bike with 7/8-inch bar mounts?
A: Yes, but you will need universal 7/8-inch to 1-1/8-inch bar mount adapters or replacement 1-1/8-inch triple clamp bar mounts to accommodate the larger clamping diameter.
Q: How does 2000-series alloy differ from 7000-series alloy?
A: 2000-series alloy offers excellent impact absorption and cost-effective durability with slightly thicker walls (5mm vs 4mm), providing a very forgiving flex feel for recreational and competitive riders alike.
Q: What is the best way to clean the throttle side before mounting the throttle tube?
A: Wipe the polished right side of the handlebar with contact cleaner and a clean rag to remove all grease or adhesive residue, ensuring zero drag on the throttle tube.
