Renthal 931-01 Fatbar36 Reed / Windham Handlebars - Black, Black

The Renthal 931-01 Fatbar36 Reed / Windham Handlebars let you set up your controls with a lightweight, high-strength bar built for motocross and off-road use. You use the 36TECH 36mm clamping standard, proprietary Zarilium alloy and a tapered 22mm control section to reduce handlebar mass and maintain the stiffness and durability you need for repeated hard acceleration, braking and landings.Discover the key features and practical outcomes you get from these handlebars:36TECH 36mm Clamping Diameter: The 36mm clamping diameter uses the engineering principle of second moment of area to position more material further from the centre line of the tube so you achieve the same bending stiffness as a conventional 28mm handlebar using thinner wall sections, which reduces total handlebar weight and helps you work against less mass every time you turn, brake or pull the bike over jumps.Tapered 36mm-to-22mm Tube Profile: The bar uses a tapered tube that transitions from the 36mm clamping area down to a 22mm control section at the grips, giving you a structure that carries higher stiffness through the centre of the bar while still accepting standard 22mm controls, so you keep familiar lever, switchgear and grip fitment and gain a front end that feels more precise when you load it into ruts, berms or braking zones.Zarilium High-Strength Alloy: The handlebar is formed from Renthal s proprietary Zarilium alloy, a material specified for high tensile strength and fatigue resistance at low wall thickness, which allows you to run a lighter tube section that still withstands repeated high impacts and twisting loads, giving you a bar that feels stable over time even when you ride hard and often.FEA-Optimised Wall Thickness and Profile: The wall thickness along the length of the tube is developed using Data Acquisition and Finite Element Analysis (FEA), giving each section of the bar a thickness tuned to the loads it experiences in racing, so you gain a balance of rigidity and flex that filters harsh impacts through the bar without feeling vague at the grips when you push into corners or land from jumps.Improved Strength-to-Weight Ratio: The R-Works Fatbar36 design delivers a 47% better strength-to-weight ratio compared to Renthal s conventional 28mm Fatbar, which means the material and profile choices give you more structural performance per gram, helping you reduce the effort you put through your arms and shoulders over a race distance while still trusting the bar under heavy compressions and flat landings.36% Handlebar Weight Reduction: The R-Works Fatbar36 achieves a 36% reduction in handlebar weight relative to the standard 28mm Fatbar by combining the larger 36mm clamp area with thinner walls and Zarilium alloy, so you remove rotating and unsprung mass from the front of the bike and feel quicker steering response when you change lines, scrub jumps or correct slides.59% Increase in Torsional Security: The larger 36mm clamping diameter improves torsional security in the bar clamps by 59% for the same applied torque on the clamp bolts, which makes it significantly harder for the handlebar to twist in the mounts during crashes or heavy hits, helping you keep your controls in line and reducing the amount of time you spend re-setting your cockpit between sessions.With this handlebar you aim to reduce how much weight you fight at the front of the bike every time you accelerate, brake and change direction, which supports smoother control inputs and helps you stay more consistent over longer motos or practice days. The combination of 36TECH , Zarilium alloy and FEA-tuned wall thickness gives you a cockpit that feels lighter in your hands yet remains composed when you push into deep braking bumps, square edges and rough landings. As part of your motocross or off-road motorcycle setup this makes a practical, smart choice if you want a lightweight handlebar that supports precise control, reliable alignment in the clamps and a more efficient ride over repeated hard laps.
