Kawasaki ER-5 (ER5-MY2005) vs Honda CBF 500 (MY2005)

Kawasaki ER-5 vs Honda CBF 500: which one to buy, and what actually separates them.

You'll roll the throttle on the Kawasaki ER-5 knowing its twin is the long-lived kind that shrugs off big mileage with basic care. On the Honda CBF 500, the same twist feeds power in one steady line with barely a buzz. It's still pulling as the needle swings high.

So which one do you buy?

The CBF 500 has the edge if…

Daily commuting & city riding

Small edge: CBF 500

For the ride to work, the CBF 500 noses ahead. Don't let that alone make the call.

What makes each one tick

ER-5

At every red light, the ER-5's 31.5 in (800 mm) seat puts the ground within easy reach. Around town the engine has usable shove, but it feels strained past the city limits and there's nothing to break the wind. The brake lever doesn't bite until you pull it firmly, and even then the single front disc only slows the bike adequately. It slips between stopped cars.

CBF 500

There's little vibration from the engine, and it wakes up once the revs climb. The levers take a light pull.

Which one for the way you ride

Comfortable long-distance riding

Both fall short

For all-day comfort, both fall short. Keep the rides short and you'll get on fine with either.

Traveling with luggage

Neither is a natural fit

If touring with luggage is the plan, keep looking. Neither one was built around it.

For twisty roads and a first bike, you won't find daylight between them. Let the test ride settle it.

  • Rear drum brake warping The rear drum can wear unevenly and eventually warp, leading to a pulsing brake pedal.
  • Corrosion of frame, fasteners, and exhaust The thin paint and poor-quality plating cause widespread rust on the frame, swingarm, and fasteners. Exhaust headers and collector box also rot through prematurely.
