Royal Enfield Bullet 650 vs BSA Gold Star 650: Detailed Comparison

Old-school thump meets twin-cylinder refinement: how do these retro 650cc machines compare?

The 650cc retro motorcycle segment has seen a resurgence in recent years, with manufacturers reviving iconic nameplates and blending them with modern engineering. The Royal Enfield Bullet 650 and the BSA Gold Star 650 are prime examples of this trend. Both bikes represent a different interpretation of classic motorcycling.

While the Bullet 650 builds upon decades of Royal Enfield heritage with its twin-cylinder platform, the BSA Gold Star 650 revives a legendary British badge with a single-cylinder engine that focuses on character and simplicity.

While both motorcycles fall into the same broad displacement category, their approach to performance, design, and rider experience differs significantly. Let’s take a detailed look at how these two retro motorcycles stack up against each other on paper:

  • The BSA’s lighter kerb weight will naturally allow it to feel more agile, even if the hardware itself is not significantly different from the Bullet 650.
  • Braking hardware is similar at the front, but the Bullet 650’s larger rear disc but that could be because of its heavier kerb weight.

  • The BSA’s wider rear tyre may provide better traction, particularly during acceleration.

  • The Bullet’s larger front wheel contributes to straight line stability, while the BSA’s smaller front wheel aids quicker steering.

Overall, the Bullet 650 slightly focuses more on stability and comfort, while the BSA Gold Star 650 leans more towards agility and responsiveness.

  • The Bullet produces slightly more power, while the BSA produces higher torque, although at a slightly higher rpm. As a result, the Bullet 650 is able to handle highway speeds in a more comfortable manner while the BSA Gold Star 650’s better tractability should make it easy to ride in the city.

  • The Bullet’s 6-speed gearbox offers better highway cruising capability.

  • In real-world riding, the Bullet 650 will feel smoother and more relaxed, especially on long rides.

  • The BSA Gold Star 650, on the other hand, will feel more engaging, particularly at lower speeds.

Verdict

The Bullet 650 is all about heritage, stability, and refinement. It offers a smoother engine, better touring capability, and a strong brand legacy. The BSA Gold Star 650, on the other hand, is lighter, more affordable, and more engaging to ride. Its single-cylinder engine delivers a unique character that stands out in a segment dominated by twins.

If you prioritise refinement, highway comfort, and brand trust, the Bullet 650 is the better choice. If you want a lighter, more characterful motorcycle with a unique riding experience, the Gold Star 650 makes a compelling case.

User Reviews

Old school character & thumpy

I was looking for a big bike that is easy to handle & has some character. BSA Gold Star has a classic & thumpy character that makes you feel like an old school charm. I'm primarily using it for city & highway rides. I have ridden it around 6000 kms that include both city & highway rides. The bike has great rear suspension & okayish front suspension (could've been improved). I prefer to setup the pre load to 4 (against the default 2) for better quality ride. Yes, Definitely go for it if you're looking for a thumpy performance & old school characterful bike. Suites best for city & highway commutes. It's a proper roadster with good mileage & lower end torque. Read More
