A 250cc Boxer engine? Patented on Benda BD250-3B

Quick Overview:

  • Chinese bike maker Benda files patent for a 250cc twin-cylinder boxer engine
  • New engine spotted on upcoming BD250-3B cruiser
  • First in segment to adopt boxer configuration at this displacement

In a world where single-cylinder thumpers dominate the 250cc category, Benda has decided to stir the pot. The Chinese motorcycle manufacturer has filed a patent for a 250cc twin-cylinder boxer engine—yes, a proper flat-twin layout—spotted on their upcoming BD250-3B. That’s a bold move in a segment that usually plays it safe.

BMW tech on a Benda?

While most manufacturers squeeze every ounce of performance from a vertically stacked engine, Benda seems to have gone horizontal. The flat-twin, or “boxer” engine layout, is famous for its use in BMW Motorrad’s heritage and touring line-up. But this? This is the first time we’re seeing something so unconventional in the quarter-litre space.

Early glimpses of the BD250-3B reveal classic cruiser styling with low-slung ergonomics, chunky forks, and a laid-back riding triangle. Think of it as a baby BMW R18 with an edgy, budget-conscious twist. That engine layout isn’t just for show either—it brings a lower centre of gravity, promising better balance and cornering confidence for newer riders.

Specs are still under wraps, but expect the boxer engine to push around 25 hp, which would put it in the ballpark of the Honda Rebel 300 and Royal Enfield’s upcoming Shotgun 350. Where it could gain the upper hand is in refinement, stability, and the “wow what’s that?” factor at red lights.

Of course, the big question is whether Benda will bring this one to global markets. In India, where anything that dares to look different earns street cred fast, this quirky flat-twin might just find a cult following—especially among retro-modern fans.

Final Thoughts

A 250cc boxer engine in 2025? That’s the kind of motorcycle mischief we live for. It might be Chinese, it might be niche, but it’s got personality—and in today’s copy-paste bike world, that counts for a lot. Here’s hoping Benda doesn’t just file patents… but sends it to production soon.
