2010 Suzuki GSX-R600 and GSX-R750

Here’s what we definitely do know: the 2010 model GSX-R1000K9 will be a carry over from this year’s bike, which shed plenty of kilos and added more ammunition compared to the predecessor.

Just ask Josh Waters how good the K9 is, after he took the bike to a debut win in the last round of the 2009 Woodstock Bourbon Australian Superbike Championship at Eastern Creek.

But here’s where it gets murky. After the 1000, speculation about what’s in store in 2010 for the two other members of the fearsome GSX-R troika, the 600 and 750, is currently pure conjecture.

We first contacted Suzuki Australia, which has no official comment, so we’ll just have to push on with what we’ve been hearing.

And it’s not really mind-blowing stuff: modest power increases for both bikes, as well as some cosmetic changes, a few nip and tucks, and further weight saving.

Dual exhaust pipes, like the 1000K9, may also be on the menu, which would mean that any weight savings found elsewhere would be offset by the addition of the second muffler.

Selectable fuel maps will adorn both machines, with street, sport and rain modes.

The GSX-R600 has been the third biggest selling supersport machine in 2009, behind the Hyosung GT650R and the more thoroughbred Yamaha YZF-R6. The Kawasaki ZX-6R is then right on the tail of the GSX-R600.

In 2008, Suzuki lifted the embargo on its 2009 GSX-R1000K9 in late September, so if that pattern continues this year it will be at least another month before official details on the 2010 600 and 750 reach the public domain.

If not then, all may be revealed at either the Tokyo Motor Show from October 24 until November 4, or at EICMA from November 10-15.

There are also rumours of a B-King-styled GSR750 for 2010, featuring the mill from the GSX-R750.

If the bike comes to fruition, the Triumph Street Triple just may have a little bit to worry about.
