Another Aussie Owner here and our fist KATANA !
It's official designation is GSX-S1000SM0. In Suzuki labelling speak is indeed an S type.
The S is defined as a Naked/Faired combo with a top half only fairing encompassing the headlight and screen, (the engine uncovered). The Bandit 1250S comes to mind as a recent example.
And we have moved on from our L series to a M series with this new KATANA edition, with the 0 indicating a year model 2020 bike.
I for a very short time was an Owner of a new Orange M109 years ago. A perfect fit for the Red Centre dust.
I was half going for the 'Busa in the same orange metallic/Black OR the M109. I should have gone the 'Busa, 1800 KM proved that for me that I was not a born Cruiser type.
Sports Bikes rule in the Adelaide Hills, but the Whyalla is suspect the roads are long , straight and flat !!!
