Suzuki's first superbike
This is my 1979 GS1000E. I bought it new. The "E" model was a step up from the standard model. It came with cast aluminum wheels, instead of spokes, and had two front discs, instead of one. I had it for two days before I changed out the cowhorn handlebars for a K&N superbike bar. At the time, it felt like clip-ons, but would be considered a touring bar nowadays.
In 1979, the Yamaha XS11 and Honda CBX were faster, but the GS had the handling. For a company that had only built two-stroke streetbikes, they had pulled out all the stops for this superbike. The frame has extra gussets all over the backbone which makes taking out the carbs extra hard. The engine has a built-up roller-bearing crankshaft, with a redline of 8,500.
The front fork is a flexible 35mm, but I installed a fork brace, and Progressive springs. The brake pads are Ferodo, the lines are braided stainless, and the fluid is silicone. Those were standard hop-up mods in the early 80's.
Unbelievably, the stock ignition was points and condenser. I changed them out to the Dyna ignition, Dyna coils, and Mallory wires. Because of the altitude, I kept the stock jetting, but got a K&N filter. I couldn't afford a full exhaust, so it's stock. It came with IRC tires, but I use Metzeler bias-ply tires. The rear is a 130, only 10mm wider than the front tire on my CBR.
The rear shocks are Works Performance, and they work terrific. I got them 1/2 longer than stock and I am almost on tippy toes at a stop. The Stebel horns will wake the dead. I used to spend all my summers doing field work, so I rode the bike a lot in the winter. Crashed once when I hit an ice patch, and tipped the bike off it's centerstand several times in the garage, so it's on it's fifth set of handlebars.
I've done every lick of mods and maintenance myself. I just cleaned the carbs, since it was sitting for a year, but I still enjoy working on it. And I really enjoy riding it. Other riders look to see what naked bike is that. Even got a few offers to buy it, but I ain't selling.
