The drivetrain is the single most abused mechanical system on a motorcycle. The reality of operating high-torque platforms like the Bajaj Dominar 400 or high-RPM commuter sports bikes like the Pulsar NS200 and RS200 is that they instantly exploit any weakness in the final drive. Installing a cheap, unbranded aftermarket chain and sprocket kit is a catastrophic mechanical error. Inferior steel sprockets warp under acceleration, and cheap chains elongate rapidly before snapping—which routinely shatters the engine casing, locks the rear wheel, and causes a high-speed crash.
This collection strictly stocks professional-grade, high-carbon steel sprockets and factory-spec drive chains for the entire Bajaj lineup. From heavy-duty sealed O-Ring and X-Ring chains designed for sustained highway touring to OEM-equivalent unsealed chains for daily urban commuters, these kits are engineered to handle the exact tensile loads and torque output of your specific Bajaj engine without premature stretching or tooth shearing.

-
O-Ring & X-Ring Heavy-Duty Kits: Mandatory for platforms like the Dominar 400, Pulsar RS200, and Avenger 220 Cruise. These chains feature internal vacuum-injected grease trapped by rubber seals between the pin and bushing. This structural isolation drastically reduces metal-on-metal friction, tripling the lifespan of the chain under heavy touring and high-speed highway loads.
-
Standard Unsealed OEM Kits: Engineered for commuter efficiency on platforms like the Pulsar 150, Platina, and CT 100. Manufactured from high-tensile carbon steel, these provide exact factory fitment and reliable daily mileage, provided strict cleaning and lubrication intervals are maintained.
-
High-Carbon Steel Sprockets: Precision-machined front (drive) and rear (driven) sprockets. Cheap sprockets utilize stamped steel with uneven tooth profiles that chew through chains. Our sprockets are heat-treated and induction-hardened to guarantee symmetrical wear and perfect roller seating, preventing the chain from skipping teeth under heavy acceleration.
Frequently Asked Questions (FAQs)
1. Can I replace just the chain and leave the old sprockets on the bike?
Absolutely not. A chain and its sprockets mate mechanically and wear together as a single unit. The pitch of the chain elongates over time, and the sprocket teeth "hook" to match that elongation. If you install a brand-new chain onto worn, hooked sprockets, the old teeth will physically tear the new chain apart, ruining it completely within 1,000 kilometers. You must always replace the front sprocket, rear sprocket, and chain simultaneously.
2. Why should I pay more for an O-Ring or X-Ring chain kit?
Unsealed chains rely entirely on the external chain lube you apply, which gets washed away in the rain or flung off at high speeds. O-Ring and X-Ring chains possess internal lubrication sealed permanently inside the rollers. They require significantly less maintenance, resist elongation, and handle the aggressive torque of 200cc+ engines without snapping. For high-displacement Bajaj models, an O-ring chain is a structural necessity, not a luxury.
3. Can I wash my O-Ring chain with petrol or diesel to clean the grime?
Doing so will instantly destroy the chain. Petrol, diesel, and harsh industrial solvents chemically degrade, swell, and crack the delicate rubber O-rings. Once the O-rings crack, the internal factory grease violently spins out at high RPM, and water enters the pins. The chain will rust internally, seize, and snap. You must strictly use a dedicated, O-ring-safe chain cleaner or pure kerosene to dissolve grime without destroying the seals.
4. How often is chain maintenance actually required?
The mechanical reality is every 500 kilometers, or immediately after riding through heavy rain or thick mud. If you fail to clean the chain before applying fresh lube, you are simply cementing abrasive sand and metal shavings into a grinding paste that rapidly machines away the sprocket teeth.
5. What happens if I ignore chain slack and run it too tight?
Running a chain without the factory-specified free play (usually 25mm to 30mm) forces the drivetrain to act as a suspension limiter. When the rear shock compresses over a pothole, the swingarm geometry tightens the chain. If there is no slack, the kinetic energy rips the front sprocket outward, immediately destroying the engine's countershaft seal, causing a massive oil leak, and potentially snapping the countershaft itself—requiring a complete engine rebuild.
