Suzuki GSX-R1000 K1: The First Gixer 1000
Words: Jeff Ware
In 2000 Honda uprated the CBR to 954cc, Yamaha had the YZF-R1 and Kawasaki, less impressively, continued with the ZX-9R. But Suzuki were still in 750 land. And despite winning races on track, the 750 was falling behind the 1000s in sales. Something had to happen.
The result was the mighty GSX-R1000. From the start, the GSX-R dominated – with 142RWHP to the R1’s 130. It was also light and extremely compact for its day. I still remember seeing one for the first time when I was a journalist at Two Wheels. Man, did it look trick.
It looked just like the current GSX-R600 and 750 but had 1000 on side of it. Amazing.
The K1 1000 frame is essentially a 750 – as is the fairing aside from the bellypan. The rear tyre was a whopping 190-section on a big 6in rim and the gold coloured fork tubes looked so, so sexy. Not to mention the massive six-pot calipers.
And just as the horsepower wars were taking off with most 1000s punching out between 125 and 130 rear wheel horsepower, the GSX-R stomped out a massive 140-plus at the rear Bridgestone. It pretty much ended the war!
It was an amazing figure for what was basically an under tuned bored (1mm) and stroked (59mm was longest in class) GSX-R750 engine. Tuners would soon be getting well over 160hp at the wheel. Life for us sportsbike riders was changed forever…
The 73mm pistons were lighter than the 750s 72mm items and the 1000 had a trick dual butterfly throttle-bodies. It also had an oil cooler and a crankshaft counter-rotating balance shaft.
To say that the GSX-R1000K1 changed the face of sportsbikes forever is an understatement. It was smooth, torquey, rideable yet with huge top end and it dominated on the streets and on the racetracks.
As soon as it was released, Honda built the 954 Blade, Yamaha stepped up the R1 and Kawasaki gave up on the ZX-9R.
With a weight of only 170kg and a top speed of 288km/h the Gixer 1000 truly was King.
