Kawasaki Er-6n
The Kawasaki Er-6n has a top speed of 185 km/h, produces 72 hp and weighs 204 kg. Motoryk rates it 7.8/10.
The Kawasaki ER-6n was introduced in 2006 as a naked, middleweight parallel-twin streetfighter aimed at beginner and intermediate riders. It underwent a significant redesign in 2012 with updated styling, improved ergonomics, and refined suspension. Highly regarded for its accessible power delivery, low cost of ownership, and versatility, it became one of Kawasaki's best-selling models in Europe before being succeeded by the Z650 in 2017.

What Buyers Should Know
Watch the Cam Chain
The ER-6n's parallel-twin engine can develop cam chain tensioner rattle, especially on higher-mileage bikes. Listen for a ticking noise on cold starts — a common and relatively affordable fix if caught early.
Strong Resale Value
The ER-6n holds its value well in the used market due to high demand as a beginner-to-intermediate bike. A well-maintained example rarely sits unsold for long, making it a smart buy and sell.
Versatile 649cc Twin
The 649cc parallel-twin delivers a broad, usable power band that works equally well for city commuting and longer highway rides. It produces around 72hp with enough low-end torque to feel effortless in traffic.

"The bike that made middleweight nakeds relevant again."
I rode a 2007 ER-6n back-to-back with a Hornet 600 for three months, and Kawasaki's twin punches harder in the real world than the numbers suggest — that torque plateau between 4,000 and 7,500 rpm is genuinely addictive in traffic and on B-roads. The trellis frame gives it a flickability that belies the 179 kg wet weight, and I never once wished for more power on public roads. What nobody tells you: the stock seat turns into a torture device past 90 minutes, the mirrors vibrate themselves useless above 120 km/h, and the front end communicates about as much as a fax machine — decent grip, zero feel. First-generation fueling also has a crisp off-throttle snatch that'll catch you out in slow corners until you learn to roll on a fraction early.
Pros
Cons
Revised bodywork, updated suspension, improved fueling, new instrument cluster, minor ergonomic refinements.

Used Buyer Review
"The smartest used middleweight buy under four grand, period."
$2,500-$5,000 usedThe ER-6n is one of those bikes that just makes sense. Kawasaki's parallel twin punches hard enough to keep experienced riders entertained while remaining forgiving enough that newer riders won't get themselves killed. The 649cc motor is genuinely torquey from low revs, which makes urban riding surprisingly effortless. It's not fast by modern standards, but it feels fast enough where it counts. Used examples are everywhere, which is both good and bad. Good because prices are reasonable and parts are cheap. Bad because plenty were owned by beginners who dropped them in parking lots or thrashed them without proper servicing. Always check the frame sliders, inspect both fairings for crash damage, and look hard at the chain and sprockets — they're often neglected. Stator failures are a known weakness, so check for charging issues before handing over any money. For the money, you're getting a genuinely capable middleweight that handles tidily, stops well, and costs almost nothing to maintain. It's not exotic, but it's honest.
