Suzuki GSX-R 750

Presenting the 2009 model year, Suzuki gives a big slap on the necks of those who expected it to reconsider making the GSX-R 750. A bike that was successfully produced for decades and has even inspired the introduction of the GSX-R 600 back in the early 1990s carries on as a unique presence on a continuously growing market, but, apparently, one in which competitors can’t see the effectiveness of the 750cc sport bike.

Suzuki has definitely got the recipe right with the GSX-R series, starting with the 600 and finishing with the Hayabusa, but one particular bike gets our attention for one good reason: you don’t see this every day! The Suzuki GSX-R 750 situates just between a middleweight and a liter class sport bike, but offers its own kind of riding excitement.

With a fuel injected 750cc liquid-cooled, inline-four, DOHC and 16 valves engine improved by the always efficient and reliable six-speed gearbox, having both reached the highest levels of development and performance, there is no wonder why some riders simply can’t jump straight on the 1000cc GSX-R and choose the 750cc model as being the most adequate for them. Another good reason is the chassis, which makes it more of a sharp handler and confidence-provider, perfect for those who feel like going through all the steps in motorcycling.

Having come a very long way, the 2009 Suzuki GSX-R 750 takes a short pit stop break this year in expectancy of the big 2010 revision so this is a good time to recapitulate its evolution.

2009 Suzuki GSX-R 750

But there is one chapter where the Suzuki won’t get beaten pretty soon at and that is looks. A veritable super sport motorcycle that offers an enough comfortable riding position without sacrificing the racing appearance that practically sells it, the 2009 Suzuki GSX-R 750 is a light (437 lbs curb weight) and compact motorcycle that gives more than a clue on the powerful engine that sits behind that nice looking fairing.

Given to the shape of the bike, once the rider takes the top speed position, he is practically part of the aerodynamic design of this GSX-R. All pieces unite perfectly to create a winning puzzle combination: the air intake, headlight, signal lights and windscreen result into a wind tunnel master. The gas tank, well positioned into the frame, allows enough space for the rider to tuck into the fairing while the seat is positioned almost horizontally, setting the GSX-R series apart from more aggressive accommodating bikes and yet which have the same results.

The GSX-R 750 has also been hooked up with a new, more aggressive exhaust which stands as the smoothest pass from plastic to metal. And this is what we love about it, the fact that you almost can’t tell which piece is part of the fairing, frame or engine and tranny, especially when you take a look at it from one side.

That effect is also created by the Black/Matte Black, Blue/White, White/Silver color schemes available for it.
The 2009 Suzuki GSX-R 750 might have a hard time finding a decent competitor for himself, but this doesn’t apply when it comes to finding owners. In fact, with a price that is close to the one of a middleweight sport bike, but offering a whole distinct touch to the GSX-R series, the 750 is easily found by riders who often come from the seat of a GSX-R 600. That is not a common situation in motorcycling these days.
