GSR600 (MY2006)

Point this at a technical mountain road and displacement stops mattering. I ran door-to-door with a bike carrying a huge power advantage by shifting constantly, braking deep, and carrying momentum through every change of direction. The only place the six-hundred gave ground was the long straights, where there's nowhere left to hide the gap. Then there's the noise. Six bikes deep at an Athens light, four-cylinders all held at the limiter and released at once, and it comes off the barriers sounding like a starting grid. Street spec, race-start sound.

Narrow bars, and the lightest input has it turning right now with no buildup and no delay. That takes a little recalibration if you've come off something lazier. In fast sweepers the quickness can read as nervous until you learn to trust it, and to Suzuki's credit the chassis never makes you choose a side: sharp and precise where the road knots up, settled where it opens out. On a tight technical road, a rider with a soft hand on those bars is close to untouchable. Two honest gaps. The conventional fork is technically faultless and leaves nothing wanting at street pace, but everything else on this motorcycle justifies an upside-down unit and anyone who knows bikes will spot that immediately. The bigger practical limit is peg clearance. At track pace I was scraping in almost every corner while the tires still had plenty left, more nerve-racking than dangerous, but it caps your lean angle until you fit rearsets.

There are two bikes in here. Below the middle of the tach it just gets on with the job, and then you keep the throttle open and the whole thing changes character on you. The front comes up in first without a jerk or a surge, no technique needed, just a clean lift with that inline-four scream behind it, and the bike feels considerably harder than its street-tuned spec has any business feeling. I came off a full track session once and found myself pinning it on the public road within a mile, which tells you what that top end does to your judgment. What surprised me more was the composure on corner entry. I gave up blipping downshifts years ago because the coordination was never there, and it made no difference: the GSR ironed out the rear jolt every time, unasked. The marks against it are both fueling. There's a small snatch when you crack it hard, and the map ships lean, so real power stays locked up until a dyno session frees it.

The stock Bridgestone all-rounder earned my trust fast. It grips across the full lean range, takes the occasional track day without protest, and should return solid mileage before it's done. Underneath, nobody value-engineered this thing. The vacuum-cast aluminum frame and swingarm use thin-walled sections with genuine structural strength, and the swingarm is massively proportioned, drawn from the sportbike catalog rather than shrunk to hit a price. It looks special and it backs that up on the road.

They never let me down when it counted. Running race pace with quicker bikes hunting me down, I never once had to ease off in a braking zone, and the GSR pulled up exactly where I aimed it, lap after lap. The one mark against them is context rather than performance. For a naked bike they're more than enough. But on a machine tuned this close to supersport everywhere else, the calipers are the single component that didn't get the memo.

Physically this bike asks very little of you. The clutch has sporty origins and still pulls clean without tiring a hand, the throws are short, and every gear locks in with a click you feel through the boot. Suzuki got the stock gearing right too, so the sprocket swap that usually follows a naked bike home never came up. What sold me was the breadth: young riders, old hands, first-timers, people who ride hard for a living, all of them came back happy. The cost is weather, and at a sustained highway clip there's simply nothing between you and the air.

Athens traffic settled this one. Constant lane-splitting, tight gaps, cars closing on me without warning, and the slim layout made it easy every time. You never think twice before filtering. The seating position pulls its weight as well: clear sightlines over the car roofs, instant response to your inputs, and enough all-around awareness that you've already reacted before you've consciously processed what's happening.
