Suzuki GSR600 (MY2006) vs SV650 (WVBY)
Suzuki GSR600 vs SV650: which one to buy, and what actually separates them.
You'll feel the Suzuki GSR600 snap into a tight bend the instant you tip it in. The Suzuki SV650 flicks over neutrally and doesn't fight the bars.
So which one do you buy?
The SV650 has the edge if…
Keeping running costs low
Inches ahead: SV650
Running costs lean slightly toward the SV650. A well-kept example of either matters more.
Daily commuting & city riding
By a nose: SV650
On the way to work, the SV650 asks a little less of you. Thank lower running costs for that. Close enough that the test ride should settle it.
What makes each one tick
GSR600
The GSR600 calms the small kick at the rear wheel just before turn-in, even when you're not blipping on downshifts. A hard twist of the throttle brings a small jerk from the lean fueling map. It isn't much, but it's there. Deep in first, the front wheel lifts by itself.
Nils rode the GSR600 in Greece, Hungary, and Styria in 2006, in Austria and Hungary in 2007, and in 2009 (NastyNils Testride).
SV650
The SV650's V-twin thrums along cleanly from barely above idle and spins up smoothly toward the top. The brake lever doesn't bite much at first, and the stopping power fades under hard use. The soft fork dives deep. The steel trellis frame steers neatly at parking-lot pace.
The Voice of Experience
What actually separates them
- The GSR600 has the lower seat: 30.9 in (785 mm) vs 31.5 in (800 mm).
- The GSR600 makes more peak power: 98 hp (72 kW) vs 71 hp (52 kW).
- The SV650 has the larger engine: 645 cc vs 599 cc.
Which one for the way you ride
Comfortable long-distance riding
Not built for this
Both of these get tiring on a long day. A proper tourer will treat you better on big miles.
A confidence-building first motorcycle
Wrong tool: GSR600
The GSR600 makes too much power to start out on. Build your skills on something smaller first.
Count twisty roads as a draw. The deal on the table and the condition of the bike matter more here.

Known problems to check before you buy
GSR600
No confirmed faults on file yet. That's not the same as fault-free.
SV650
- Fuel tank weld cracking (California models) Recall 06V013000 On California-spec SV650s (2003–2006), the bracket for the liquid/vapor separator can crack from vibration, leading to fuel leakage. NHTSA recall 06V013000 required fuel tank replacement.
- Front spark plug water ingress The design of the front cylinder spark plug recess allows water and debris to accumulate, especially after washing or riding in heavy rain, causing an engine misfire.
- Oil starvation during extended wheelies The V-twin's oil pick-up can be starved during prolonged wheelies, potentially leading to bearing damage. This is a risk for stunt riders and not a concern for normal street riding.
- Green connector wiring chafe The wiring harness near the steering head or under the seat can chafe, causing intermittent shorts. The most common failure is the 'green connector'—the ignition switch or main harness plug—which causes sudden loss of power or no-start conditions.
