CHAIN SPROCKET BAJAJ BAJAJ PULSAR 135 CC IND HARD

The Chain Sprocket Bajaj Bajaj Pulsar 135 Cc Ind Hard delivers robust final drive power transmission, silky smooth throttle pickup, and long-lasting drivetrain reliability for your motorcycle. Manufactured to stringent OEM engineering tolerances, this heavy-duty chain and sprocket kit replaces stretched, kinked, or hooked factory drive sets, restoring maximum engine torque to the rear wheel without energy-wasting friction or chain whip.

Workshop Guide & Diagnostic Standards for Chain Sprocket Bajaj Bajaj Pulsar 135 Cc Ind Hard

Upgrading your two-wheeler with this matched Chain & Sprocket set guarantees correct pitch engagement, preserves engine countershaft bearing life, and eliminates harsh vibration pulses during acceleration and engine braking.

1. High-Tensile Alloy Steel Roller Drive Chain Metallurgy

Engineered from cold-drawn high-tensile alloy steel, the drive chain features solid seamless bushings and quad-staked link pins. This solid-bushing construction eliminates barrel distortion under high shock loads, providing superior resistance to pin galling, link kink tight spots, and chain elongation over extended high-mileage running.

2. Induction-Hardened High-Carbon Steel Rear Sprocket Teeth

The rear wheel sprocket is blanked from high-tensile S45C carbon steel sheet and undergoes computer-controlled high-frequency induction hardening on all gear teeth (HRC 55 to 60). This ultra-hard outer surface finish prevents premature tooth thinning and shark-fin hooking while retaining a tough, ductile core to absorb sudden drivetrain shock shocks from aggressive downshifts.

3. Precision CNC Case-Hardened Countershaft Front Sprocket

Rotating at approximately triple the speed of the rear sprocket, the small engine countershaft sprocket is hobbed from premium SCM420 chromium-molybdenum alloy steel and deeply carburized. Micron-accurate tooth profile machining ensures whisper-quiet roller entry and departure, preventing high-speed transmission whine and front sprocket pocket wear.

4. Pitch Alignment, Sprocket Ratio & Optimal Drivetrain Torque Delivery

Calibrated to original factory gear ratios, this drive kit preserves intended engine torque curves and factory acceleration dynamics without causing engine bogging or excessive highway cruising RPMs. The precision link pitch tolerances ensure smooth roller seating without pitch hunting or link binding.

5. Heavy-Duty Quad-Riveted Pins & Chain Lubrication Retention

Every link pin is fastened using hydraulic quad-rivet staking, ensuring that outer link plates cannot push outward under heavy side-loading or rear swingarm flex. Deep lubricant retention channels keep specialized synthetic high-pressure chain grease locked inside the bushing interface, resisting wash-off from monsoon rainwater and road grime.

6. Smooth Power Delivery, Anti-Whip Rigidity & Sprocket Carrier Dampening

High lateral rigidity along the entire chain length minimizes side whip and flailing against your chain guard or rear tire. High dimensional uniformity ensures uniform tension across the entire swingarm arc, delivering smooth power pulses through your rear wheel hub rubber cush drive dampeners.

7. Workshop Installation Protocols, Chain Slack Measurement & Laser Alignment

Professional installation requires thorough degreasing of the rear sprocket carrier and engine countershaft. Inspect rear hub rubber cush drive dampers and replace if cracked. Adjust chain slack strictly to factory specifications (typically 20 to 30 mm free play midway along the lower run with rider weight), align rear wheel axle adjusters evenly using swingarm index marks, and secure the master link spring clip with its closed end pointing in the direction of chain rotation.

Comprehensive Two-Wheeler Buyer Guide & Diagnostic Checklist

• Hooked or Pointed Sprocket Teeth: When rear sprocket teeth lose their symmetrical curved valley profile and curve forward like shark fins, the sprocket is severely worn and will quickly destroy any chain fitted to it.
• Chain Tight Spots & Stiff Links: Uneven chain elongation creates alternating tight and loose chain slack when rotating the rear wheel by hand. This indicates dry pin galling requiring immediate kit replacement.
• Drivetrain Chatter & Slapping: Excessive chain slack or worn sprocket teeth generate audible slapping noises against the swingarm chain slider rubber during deceleration.
• Chain Pull-Off Test: Grasp the chain at the 3 o’clock position on the rear sprocket and pull outward. If the chain lifts more than halfway off the sprocket teeth, the pitch is stretched and worn beyond safety limits.
