Kawasaki W650
The Kawasaki W650 has a top speed of 175 km/h, produces 50 hp and weighs 202 kg. Motoryk rates it 8/10.
The Kawasaki W650 was introduced in 1999 as a modern homage to the classic British-style parallel twin motorcycles of the 1960s, particularly inspired by the legendary Kawasaki W1 of 1966. It was designed to capture the retro aesthetic and character of vintage bikes while incorporating modern reliability and engineering, featuring a bevel-gear-driven twin cam engine that mimics the look of classic pushrods. The W650 developed a devoted following among café racer and retro enthusiasts and was produced until 2007, later being succeeded by the fuel-injected W800 in 2011.

What Buyers Should Know
Bulletproof Engine Reliability
The W650's parallel-twin engine is widely regarded as exceptionally reliable with minimal major failures reported. Regular oil changes and valve clearance checks are virtually all it needs to run for decades.
Watch for Carb Issues
Sitting bikes commonly develop clogged carburetors due to old fuel varnish buildup — always ask about storage history. A carb clean or rebuild is inexpensive but is the most frequent issue buyers encounter.
Strong Resale Value
The W650 holds its value unusually well due to its discontinued status (produced 1999–2008) and cult following among retro-café enthusiasts. Clean examples often sell for close to purchase price years later.

"The most honest motorcycle Kawasaki ever built."
I put 14,000 kilometres on a 2002 W650 and still think about it more than bikes that cost three times as much. That bevel-gear cam drive makes a mechanical sound unlike anything else — a faint, precise whirr under the exhaust note that reminds you engineering can be art. It's not fast, and 50 horsepower feels exactly like 50 horsepower, but the torque curve is so linear and the throttle response so clean that urban riding becomes genuinely meditative. The real frustration is wind protection: above 130 km/h you're just fighting physics, and the chrome bits — beautiful as they are — start pitting if you look at them wrong in a wet climate.

Used Buyer Review
"The most honest classic twin money can currently buy used."
$3,500-$6,500 usedThe W650 is one of those bikes that gets under your skin in a way that's hard to explain rationally. It's not fast, it doesn't handle like a sportsbike, and the technology stopped evolving around 1999 — because that's essentially the point. Kawasaki built something that looks and feels like a 1960s British twin but actually starts first kick, doesn't leak oil, and won't strand you roadside. That parallel twin with its bevel-gear-driven cams sounds absolutely gorgeous at a steady cruise. Used examples need careful inspection around the carb diaphragms — they crack and cause flat spots that frustrate new owners who blame the engine. Check the fork seals, too; they're a known weak point on higher-mileage bikes. Cam chain tensioners occasionally rattle on cold starts but usually self-resolve once warm. Parts availability is decent but not brilliant, so budget accordingly. If you want a genuine café racer base or a Sunday morning machine that makes you smile without destroying your wrists, this is genuinely special. Just don't expect it to keep pace with modern traffic.
