Long story short: There’s been a lot of debate since the new Royal Enfield Bullet 350 came out. People keep asking if it’s better than the old one. Let’s finally clear things up.
Hello everyone, my name is Hiran Narayanan, owner and chief content writer at Bikeleague India. I have been meaning to write an editorial for a while, and inspiration struck after I purchased the new Royal Enfield Bullet 350 a month ago.
I have ridden a Royal Enfield Bullet 350 ES for over six years, covering around 60,000 km. Having experience with both the older and the new Bullet 350 models, it was the right time to share my perspective. In this article, I will compare every aspect of both generations in detail.
Key Takeaways
- The new Bullet 350 has a 349cc, SOHC, 20bhp, 27Nm torque, counterbalanced for fewer vibrations, smoother at high speeds.
- The old Bullet 350 has a 346cc, pushrod UCE, 19bhp, 27 Nm torque, raw vibrations, rugged at high speeds.
- The old Bullet 350 utilised a single downtube frame, lighter but less stable at high speeds. The new Bullet 350 features Twin downtube frame, more stable, better cornering and high-speed control .
- The old Bullet 350 is more balanced, stable in turns, confidence-inspiring, suitable for city and highway use. The new Bullet 350’s Lighter, nimble at slow speeds, but wobbly on turns or bumps at high speeds.
- Vibration levels are minimal in new Bullet 350 due to counterbalancer, refined ride. While on the older Bullet 350 there are higher vibrations and has characteristic Bullet thump.
Comparison between New Royal Enfield Bullet 350 vs old Bullet 350
1. Engine of old & new Royal Enfield Bullet 350
The most significant change in the motorcycle is the engine. The new Royal Enfield Bullet 350 features a smoother, slightly larger engine (349cc) compared to the old one (346cc).
This engine, also found in the Meteor 350 and Classic 350, provides slightly more power: approximately 20 bhp in the new model, compared to 19 bhp in the old. The pulling strength (torque) stays nearly the same at 27Nm. As a result, the ride is smoother and vibrates less than the old Bullet.
In summary, the new Bullet 350 offers a smoother and more powerful ride at higher speeds. At the same time, the old Bullet retains its rugged, classic feel, which long-time fans appreciate. Purists may prefer the older model, but the new model stands out for its improved performance above 60km/h.
2. Fit & Finish
The new Bullet 350 feels better built. The switches, footrests, and other parts feel stronger and fit better. The paint also appears more even and less likely to chip, with a wide range of colour choices. There are also many company accessories available for this model, which are very useful.
Older Bullets sometimes had loose parts, uneven gaps, and paint problems. Still, this roughness gives them a classic charm that some riders like. There are fewer official accessories, so owners often use third-party parts.
3. Electrical System
The old Bullet created a spark to start the engine using a spinning magnet and needed just basic lights and a foot lever to start. The new Bullet 350 utilises a battery and generator to start with the push of a button. There is no foot lever to start it in any new Bullet 350.
The new part-digital display shows both pointer dials and numbers for better information. This includes speed, fuel left, total and trip distance, clock, brake safety light, battery warning, and other valuable things. A USB charger lets you charge devices easily. Older models only showed speed and distance with pointer dials, and sometimes didn’t even have a fuel gauge.
The latest Bullet 350 uses conventional bulbs for the front, rear, and signal lights, rather than modern LED ones. However, the battery does not require maintenance, which is a significant advantage and a standard feature in all new models.
4. Chassis
The old Bullet utilised a simple main support bar, which was less sturdy and made it more difficult to control at high speeds. The new Bullet 350 features two stronger support bars, providing better control and steadiness when turning or riding at high speeds. Older Bullets were less stable at higher speeds, but the new one fixes this problem.
5. Suspension of old & new Royal Enfield Bullet 350
The old Bullet had basic front shocks, which didn’t control bumps well, especially on uneven roads. The back springs could not be adjusted significantly, resulting in a less comfortable ride. Oil-filled shocks didn’t handle bumps as well as gas-filled ones.
In the new Bullet, the thicker front shocks give more control and steadiness, especially when stopping or turning. The back springs can be adjusted, allowing you to set them up for your weight or preferred riding style. This makes the ride smoother and easier to handle.
The new Bullet 350’s gas-filled shocks are superior to the oil-filled ones used previously. Gas-filled shocks handle bumps more effectively, providing a smoother ride.
6. Ride quality & refinement
The old Bullet 350 was more comfortable at slower speeds. Its soft suspension made small bumps less noticeable during slow rides. However, the simple frame and shocks made it wobbly, especially in turns or when travelling at high speeds. The engine also vibrated a lot, which could tire riders on long trips.
The new Bullet 350 is comfortable at any speed. Its stronger frame and improved shocks make the ride smoother, even on uneven roads. The new engine also reduces shaking, making rides much more pleasant.
7. Handling old & new Royal Enfield Bullet 350
The old Bullet 350 is lighter and easier to move slowly. Its thin tyres and simple frame make it easy to manoeuvre in tight spots. But the weaker frame and suspension made it less steady when turning or hitting bumps.
The new Bullet 350’s stronger frame and improved suspension provide you with more control and confidence, even when turning or riding at high speeds.
The discontinued Bullet 350 offered a certain charm with its smoother ride, particularly on highways. The latest Bullet 350 delivers a more balanced and confidence-inspiring riding experience, from cruising to navigating city streets.
8. Braking system
The old Bullet used a disc brake in front and a drum brake at the back, which meant it didn’t stop as well. The back brakes made noise and needed more maintenance. There was a brake safety system (ABS), but it only worked for the front wheel, making it less safe than systems that work on both wheels.
A big improvement in the new Bullet is that it has disc brakes on both wheels. It also comes with a safety brake system for both wheels in some versions, providing customers with more options.
9. Maintenance & Service
In the discontinued Bullet 350, periodic adjustment of valve clearances in the engine is required due to wear and tear. Regular adjustments may be necessary to maintain an optimal air-fuel mixture for smooth operation and optimal fuel efficiency. The chain requires more frequent attention.
Easier access to specific mechanical components due to a less complex design. Parts might be more readily available and potentially cheaper. The more straightforward design might be more approachable for riders who are comfortable with essential mechanical work.
The new Bullet 350 automatically adjusts valve clearances, reducing the need for manual intervention. Fuel injection (EFI) manages the air-fuel mixture, offering a more consistent and hassle-free experience. The sealed chain design requires less frequent lubrication and adjustment.
Modern features like fuel injection require specialised tools or expertise for repairs. With more complex systems, proper maintenance may require relying on trained professionals at authorised service centres.
The discontinued Bullet 350 requires frequent adjustments, but it may be more accessible for DIY maintenance due to its simpler design. Due to the more complex systems, less frequent adjustments in the new Bullet might require relying on service centres for specific maintenance tasks.
10. Color options
The colour variants are now precisely seven, with chrome options available in all six colours. Notably, in the most premium variant, Black Gold, there is no chrome at all. Single-channel ABS is a standard option in all variants.
At the same time, Standard Black, Standard Maroon, and Black Gold dual-channel ABS are standard. The Madras line on the fuel tank is unavailable on military black and military red colour options.
In the old generation, colour options were minimal. Dual-channel ABS was unavailable in colour variants; only single-channel ABS was a standard option.

Our opinion
The discontinued Royal Enfield Bullet 350 embodied a raw, classic riding experience, marked by its trademark “thump.” While charming, comfort, and refinement were not its primary focus. The new Royal Enfield Bullet 350 prioritises comfort and a smoother ride while retaining the iconic silhouette. Stricter emission regulations might slightly subdue the “thump.”
Still, the overall experience caters to a broader range of riders who value heritage and modern features. The ease of repairs and DIY in older bullets is not passed on to the new generation bullet. Additionally, the new Bullet technology is sophisticated, which may impact long hauls in the event of a breakdown.
Conclusion
Younger riders, such as Gen Z and Alpha, may prefer the new Bullet, while many long-time fans from older generations might not. I count myself among the traditionalists. Still, I can’t ignore the new Bullet’s features, comfort, and performance—they make it hard to resist.
There’s a trade-off between the classic engine thump and vintage feel of older Bullets and the updates in the new model. Royal Enfield needs to keep up with changing times and new riders, especially since competitors are adding more advanced features.
