Yamaha Srx 600
The Yamaha Srx 600 has a top speed of ~160 km/h (estimated; note: varies by market and tuning), produces ~45 hp and weighs ~155 kg. Motoryk rates it 7.5/10.
The Yamaha SRX600 (also known as the SRX-6) was introduced in 1985 as a stylish single-cylinder four-stroke roadster, aimed at riders who appreciated minimalist, classic motorcycle design in the tradition of British singles. It featured a DOHC 608cc single-cylinder engine, making it one of the more sophisticated large-bore singles of its era, and was particularly popular in Japan and European markets. The model was discontinued in the early 1990s but remains a cult classic among enthusiasts who value its lightweight handling, clean aesthetics, and characterful engine.

What Buyers Should Know
Single-Cylinder Simplicity
The SRX600 uses a straightforward air-cooled single-cylinder SOHC engine, making maintenance accessible and parts relatively easy to source. This simplicity contributes to long-term reliability when properly serviced.
Watch the Carb & Valves
Common issues include carburetor gumming from sitting unused and tight valve clearances that cause hard starting — always inspect both before buying. A compression test and recent valve service history are essential checkpoints.
Rising Retro Collectibility
The SRX600 is a cult classic with a devoted following, and clean examples are steadily appreciating in value as retro-cafe styling remains popular. Low-mileage, unmodified bikes command a significant premium over modified ones.
Generations & Specs by Year
Single-cylinder 608cc SOHC engine, minimalist retro styling, dual rear shocks, traditional wire wheels introduced.
"Japan's answer to the café racer question, beautifully asked."
The SRX 600 is one of those bikes that rewards patience — that 608cc thumper needs to be above 5,000 rpm before it really wakes up, but when it does, the torque surge through a canyon road is genuinely addictive. Dry weight under 170 kg means this thing changes direction with an honesty that modern bikes have largely forgotten, and the wire wheels give it a flex and feedback you don't get from cast alloys. The dual shocks are the weak point — stock units are wallowy under hard braking and don't inspire confidence mid-corner, and heat soak on stop-start city riding can make the single grumpy and prone to vapor lock. But ride it the way it wants to be ridden — open roads, committed pace, minimal luggage — and the SRX 600 is a genuinely special machine that explains why it quietly became a cult bike while the market was busy chasing four-cylinder speed.

Used Buyer Review
"A rewarding, characterful thumper for patient, spanner-savvy enthusiasts only."
$2,500-$5,500 usedThe SRX600 is one of Yamaha's forgotten gems — a thumper that punches well above its displacement and looks genuinely stunning doing it. That single-cylinder 608cc engine pulls hard from low revs and sounds absolutely brilliant with a decent exhaust, but fair warning: it vibrates. Not unpleasantly, but you'll know there's a piston the size of a dinner plate doing its thing beneath you. Used examples are getting scarce and sellers know it. Inspect the frame carefully around the headstock — these were ridden hard by people who thought they were Kenny Roberts. Carb rebuilds are almost always needed on neglected bikes, and the starter system has a reputation for drama. Budget for that upfront rather than discovering it roadside. Parts availability is the real conversation killer. Yamaha Japan made these primarily for the home market, so sourcing isn't impossible but it's never easy either. Join the online communities before buying — those people will save you money and sanity in equal measure.
