YAMAHA FAZER BIKE JHULA REAR U

The Yamaha Fazer Bike Jhula Rear U delivers rock-solid chassis rigidity, laser-straight rear wheel tracking, and reliable heavy-load carrying capacity for your motorcycle. Fabricated from heavy-gauge seamless carbon steel to exacting OEM dimensional and structural standards, this heavy-duty swingarm (bike jhula / rear U) replaces bent, rusted, or bushing-worn factory swingarms, restoring precise road holding and riding confidence across all road conditions.

Workshop Guide & Diagnostic Standards for Yamaha Fazer Bike Jhula Rear U

Upgrading your two-wheeler with this factory-aligned Bike Jhula, Rear U guarantees correct rear suspension geometry, prevents aggressive rear tire side-wear, and eliminates dangerous rear-end fishtailing under heavy pillion or luggage loads.

1. Heavy-Gauge Rectangular & Tubular Carbon Steel Swingarm Geometry

This swingarm is manufactured from high-tensile cold-rolled seamless carbon steel with a heavy wall thickness exceeding 2.5 mm. Structural box-section side beams provide maximum torsional stiffness against lateral bending moments generated during high-speed cornering and sudden avoidance maneuvers, keeping your rear wheel tracking true.

2. Pre-Fitted Needle Roller / Phosphor-Bronze Pivot Bushing Engineering

The pivot tube comes pre-pressed with OEM-grade precision-machined phosphor-bronze or rubber-bonded silentbloc bushings. Reamed to exact micron internal diameters, they ensure smooth, friction-free swingarm articulation through the suspension stroke while eliminating sloppy side-to-side pivot play.

3. Shock Absorber Mount Lug & Chain Adjuster Bracket Strength

Heavy-duty gusseted mounting studs for rear shock absorbers and reinforced chain adjuster end blocks are welded with automated precision. Substantial bracket thickness prevents weld fatigue cracking and thread stripping during heavy shock compression over severe potholes.

4. Robotic MIG Welding & Torsional Alignment Verification

Every joint undergoes continuous automated robotic MIG welding with deep metallurgical penetration. Finished assemblies are checked on precision three-dimensional alignment jigs to verify zero torsional twist and absolute parallelism between the front pivot axle and the rear wheel axle slots.

5. Multi-Coat Powder Coated Anti-Rust Baked Finish

Before painting, the steel undergoes thorough chemical degreasing, shot-blasting, and iron phosphate anti-rust conversion coating. A heavy electrostatic layer of epoxy powder coat is baked at 200°C, producing a resilient, high-gloss chip-resistant barrier that withstands monsoon mud slurry and road grit scouring.

6. Rear Wheel Axle Slot Straightness & Laser Tracking Stability

The rear axle drop-out slots are CNC-milled with calibrated laser index alignment marks. This enables workshop mechanics to set perfectly equal chain tensioner distances on both sides, ensuring parallel drive chain alignment and preventing rear sprocket tooth side-loading.

7. Workshop Installation Protocols, Pivot Bolt Greasing & Torque Guidelines

Professional installation requires thorough cleaning and high-pressure molybdenum disulfide grease lubrication of the main pivot bolt shaft before insertion through the bushings. Align the swingarm squarely into the main frame cradle, torque the self-locking pivot nut to factory torque specifications (typically 50 to 65 Nm), and check for smooth up-down movement without lateral binding.

Comprehensive Two-Wheeler Buyer Guide & Diagnostic Checklist

• Rear Wheel Side Wobble (Play at Rim): Place bike on center stand and grasp the rear tire at the top and bottom. Rocking it side-to-side will reveal worn swingarm pivot bushings or a loose pivot shaft bolt.
• Chain Derailed or Constant Slack Issues: A twisted swingarm pulls the rear wheel out of alignment with the engine countershaft sprocket, causing the chain to hop off the teeth under sudden acceleration.
• Uneven Rear Tire Tread Wear: When one shoulder of your rear tire wears down much faster than the other, the swingarm has sustained structural twist from a previous collision or pothole hit.
• Creaking Noise Over Speed Breakers: Dry, rusted, or deteriorated swingarm pivot bushes create loud metallic creaks whenever the rear suspension compresses.
