Compatibility Table

Note: This Rolon OR F407 kit (14T/46T, 126-pitch chain) has been the standard specification for all TVS Raider 125 models since the bike's launch in 2021. The kit fits all brake configurations (drum/disc), all seating options (single/split), and all feature variants (standard/iGO/connected/ABS). If your Raider has any non-standard modifications (performance exhaust with different gearing requirements, aftermarket rear wheel), please verify fitment with your mechanic or contact Under The Hood before ordering.

Variants

This Rolon OR F407 kit comes in a single standard steel configuration:

• 14-tooth front sprocket (carbon steel, heat-treated)
• 46-tooth rear sprocket (carbon steel, induction-hardened)
• 126-pitch chain (standard series with rust-preventive coating)

Who should choose this kit?

This standard Rolon kit is ideal for:

• Daily commuters who prioritize reliability, longevity, and low maintenance over outright performance
• Budget-conscious riders seeking genuine OEM-quality replacement at accessible pricing (₹1,500-1,600 range)
• First-time chain replacements on bikes with 15,000-25,000 km where original equipment is worn
• City + occasional highway riders who maintain the Raider's balanced character (quick city acceleration, comfortable cruising at 70-80 km/h)
• Riders in coastal/monsoon regions who need rust protection but don't require brass chain's extreme corrosion resistance

Why this 14T/46T gearing? TVS engineered this ratio to deliver the Raider's signature sporty feel—punchy acceleration from traffic lights, responsive throttle in city conditions, and best-in-class 0-60 km/h performance (5.9 seconds). This Rolon kit maintains that character while offering superior durability compared to stock TVS chains.

Note on Rolon's brass chain option: Rolon does not currently manufacture a brass chain variant for TVS Raider 125. The OR F407 standard steel kit is the primary Rolon offering for this model, delivering excellent value and performance for typical riding conditions. For extreme corrosion resistance (coastal areas with salt spray, heavy monsoon riding), consider more frequent maintenance or contact Under The Hood for alternative solutions.

Installation & Maintenance Notes

Installation Tips:

• Professional installation recommended: While mechanically skilled riders can replace this kit with basic tools (17mm/19mm spanners, chain breaker, circlip pliers), proper sprocket alignment, chain tension, and master link installation are critical for safety and longevity. Under The Hood offers installation services for Varanasi and surrounding areas.
• Inspect related drivetrain components: Before installing your new Rolon kit, check the chain slider, chain guide, and rear wheel hub bearing for wear. Replace worn components simultaneously to maximize the new kit's service life.
• Chain tension specification: Maintain 20-30mm vertical free play measured at the midpoint between sprockets with the bike on its center stand in neutral. The Raider's manual specifies this range for optimal performance and component life.
• Master link orientation: Ensure the master link clip opening faces opposite the chain's direction of travel (away from forward rotation) to prevent clip dislodgement during hard acceleration.
• Sprocket bolt torque: Front sprocket nuts and rear sprocket bolts must be torqued to TVS specifications (typically 35-45 Nm) to prevent loosening. Use threadlocker on rear sprocket bolts for added security.

Maintenance for Maximum Life:

• Lubrication interval: Clean and lubricate chain every 600-800 km for city riding, or after every rain/dusty ride. Use motorcycle-specific chain cleaner (kerosene acceptable in a pinch) followed by quality 126-pitch chain lube. Rolon chain lube is available at Under The Hood.
• Tension checks: Inspect chain slack every 1,000 km or if you notice performance changes. Adjust as needed to maintain 20-30mm free play. Uneven tension (tight spots when rotating the wheel) indicates sprocket or chain wear and requires immediate attention.
• Replacement indicators: Replace the entire kit when:
  • Chain has elongated beyond adjustment range (adjuster near end of swingarm)
  • Sprocket teeth show visible hooking/shark-fin profiles
  • You experience skipping under load or hear metallic grinding sounds
  • Chain has tight spots that don't correspond to specific rear wheel positions
• Riding habits that extend life:
  • Avoid aggressive throttle blips from standstill (spins chain on sprockets)
  • Maintain proper chain tension—neither too tight nor too loose
  • Keep chain clean and lubricated, especially after monsoon/dusty rides
  • Use the Raider's Eco mode for most city riding (reduces drivetrain stress)
  • Expected lifespan: 20,000-25,000 km with excellent care, 15,000-20,000 km under average conditions, 12,000-15,000 km with poor maintenance or aggressive riding

Safety Reminders:

• Never ride with excessive chain slack (risk of chain derailment, which can lock the rear wheel or damage engine cases)
• Never over-tighten the chain (damages gearbox output bearing, rear wheel bearing, and causes premature chain wear)
• Check chain tension before long rides, especially when carrying pillion or luggage (added weight increases chain stress)
• If you hear unusual drivetrain noise after installation (grinding, clicking, or whining sounds), stop immediately and recheck installation—do not continue riding

FAQs 

Q1: Is this Rolon OR F407 kit compatible with my 2024 TVS Raider 125 SXC with ABS?
A: Yes, absolutely. The Rolon OR F407 kit (14T/46T, 126-pitch) is the standard fitment for all TVS Raider 125 models from 2021 to present, including all brake configurations (drum/disc/ABS), seating options (single/split), and feature variants (standard/iGO/connected/TFT). The drivetrain specifications have remained consistent across all Raider generations and special editions. Your 2024 SXC ABS model uses the exact same chain and sprocket specification as the original 2021 Raider.

Q2: How is this Rolon kit better than the cheaper ₹700-900 chain sets available on Amazon/Flipkart?
A: Rolon is India's premier OEM chain manufacturer—the same company that supplies chains to TVS, Hero, Bajaj, and other major brands from the factory. Generic ₹700-900 kits typically use softer mild steel with inconsistent heat treatment, resulting in rapid wear (often just 10,000-12,000 km lifespan), frequent adjustment needs, and eventual failure that can damage other drivetrain components. Rolon kits undergo 18 production stages and 15 quality checks at ISO-certified facilities, use premium carbon steel with precise heat treatment, and deliver 20,000-25,000 km service life—nearly double the lifespan. The initial cost difference (₹600-700 more) pays for itself through longer life, better fuel efficiency (less friction loss), fewer maintenance stops, and peace of mind. You're also supporting the same quality TVS trusts for factory assembly.

Q3: Will this kit affect my Raider's 0-60 km/h time, top speed, or fuel economy?
A: No. This Rolon kit maintains the factory 14T/46T gear ratio that TVS engineers selected for the Raider's character. Your best-in-class acceleration (0-60 km/h in 5.9 seconds), top speed (99 km/h), comfortable cruising speeds, and excellent fuel economy (65-72 kmpl claimed) will remain exactly as designed. If you're replacing a heavily worn kit, you'll likely notice improved performance—sharper throttle response, smoother power delivery, and slightly better mileage as power losses from a stretched chain and worn sprockets are eliminated. The Raider's Power/Eco riding modes will continue working as intended with this kit.

Q4: Does this kit come with a warranty? What if I receive a damaged or defective part?
A: As a genuine Rolon product purchased from an authorized distributor (Under The Hood), this kit is covered under Rolon's standard manufacturing warranty against defects. If you receive a damaged or defective component, contact Under The Hood immediately with photos.

Q5: Do I need to buy chain lube, cleaner, or any additional parts separately?
A: The kit includes all components needed for drivetrain replacement (sprockets, chain, master link). However, you'll need installation hardware if not reusing your old parts:

• Front sprocket: locknut, lock washer, and washer (typically reused from old kit)
• Rear sprocket: 6 bolts with lock washers (typically reused; inspect for damage)
• Axle nut and cotter pin (reused)

For maintenance, we strongly recommend purchasing separately:

• Motorcycle-specific chain cleaner (or kerosene)
• 126-pitch chain lube (Rolon brand available at Under The Hood)
• Soft brush for chain cleaning

You'll also need basic tools: 17mm/19mm spanners, chain breaker or master link pliers, torque wrench, and possibly circlip pliers depending on your Raider's axle design.

Q6: How long will this kit last with daily city commuting and occasional weekend highway rides?
A: With proper maintenance (regular cleaning and lubrication every 600-800 km, correct tension adjustment), expect 20,000-25,000 km from this genuine Rolon kit under normal riding conditions (daily commute, occasional pillion, moderate luggage, mixed city-highway use). Harsh conditions may reduce lifespan to 15,000-20,000 km:

• Heavy Raider use in dusty/unpaved conditions
• Frequent pillion + full luggage (increases chain stress)
• Poor maintenance (infrequent lubrication, incorrect tension)
• Aggressive riding style (hard acceleration, high-rpm shifts)

This is significantly longer than most aftermarket kits (10,000-15,000 km typical) and comparable to or better than original TVS equipment. Replace when you notice elongation beyond adjustment, sprocket tooth hooking, or unusual drivetrain noises.

Q7: Can I install this kit myself, or should I visit a mechanic?
A: If you have mechanical experience and proper tools (spanners, chain breaker, torque wrench), you can install this kit following your Raider's service manual. However, proper installation requires:

• Correct removal of old chain/sprockets without damaging other components
• Precise sprocket alignment and bolt torque specifications
• Accurate chain tension adjustment (20-30mm free play)
• Proper master link installation and clip orientation
• Post-installation safety checks

Incorrect installation can cause chain derailment (extremely dangerous), premature wear, or damage to gearbox/wheel bearings. For most riders, professional installation is safer and ensures warranty protection. Under The Hood offers installation services for Varanasi-area customers at competitive rates, typically completed within 1-2 hours. If DIY installing, have an experienced mechanic verify your work before riding.
