❓ Frequently Asked Questions

Q: Can I use aftermarket service kits instead of genuine Royal Enfield?

A: Yes, but quality varies. During warranty period, use genuine RE kits. After warranty, reputable aftermarket brands are acceptable. Our kits are OEM-grade quality.

Q: What engine oil should I use for Classic 350?

A: J-Series: 10W-50 or 10W-40 semi-synthetic. UCE: 20W-50 mineral or 10W-50 semi-synthetic. Always use JASO MA2 certified motorcycle oil.

Q: How often should I change engine oil?

A: J-Series: Every 10,000 km or 1 year (whichever comes first). UCE: Every 6,000 km or 1 year. If you ride in dusty conditions or short trips, change every 5,000 km.

Q: Do I need to service at Royal Enfield dealer to maintain warranty?

A: No, but you must follow the service schedule and keep records. Using genuine parts is recommended during warranty period.

Q: What happens if I skip a service?

A: Engine wear increases, fuel efficiency drops, warranty may be voided, and you risk expensive repairs. Regular service is cheaper than engine rebuilds!

Q: Can I extend service intervals to save money?

A: Not recommended. Royal Enfield's service intervals are already optimized. Extending them risks engine damage and voids warranty.

Q: What's the difference between 10,000 km and 20,000 km service kits?

A: 20,000 km kits include additional items like brake pads, coolant, fork oil, and more comprehensive gaskets. It's a major service vs routine service.

🏆 Genuine vs Aftermarket: Which to Choose?

Our Recommendation: Use genuine RE kits during warranty (first 2 years). After warranty, OEM-grade aftermarket kits offer excellent value.
