I know a guy who had to prove limited production status to get cheap insurance on his R90S [1500 units or less per year] and this is the case for R90S's. So, 3600 vs 4800 machines,,,,,,,we're cutting it close here.

I still go back to my original thoughts that the Brough SS100 is THE first.
you are correct about overall production numbers for RC30 .. only about 316 made it into USA. but they were spread out rest of world pretty evenly. total production numbers of 4782 means RC30 was a production bike.

but R90S was first introduced in USA for 1974, earlier in Europe. RC30 was first produced in 1987.

Brough SS100 certainly predated everything and ahead of it's time. but compared to a modern motorcycle's handling, dual disc brakes, wind tunnel fairing, etc.

claim of Brough SS100 being the first superbike certainly has merits. but it was R90S that spawn off our current crop of Sportbikes. all with excellent handling, disc brakes, powerful engines, wind tunnel fairing, etc.

Other than the disk brakes, Moto Guzzi had all that in the 1950s.

I can't believe there's no catch screen behind the bike to keep debris out of the propeller, things like parts and the rider.........

Unless I'm very much mistaken, Neilson's California Hot Rod won the season opening 1977 Daytona superbike race, but never the championship.

Yep. In the back lot at Guzzi's factory at Mandello del Lario.

There is mesh, just not real visible in that old pic.


Here's some early '70s action;

Yeah, I checked it out in 2010. They don't run it up anymore, as it ends up killing the power to the town.

I think an important thing to consider in this discussion is not only the ability to go fast and turn but also being able to slow down quickly....
In the 60's when Jaguar changed over their cars to disc brakes they started smoking Ferrari and ironically Enzo wasn't sold on disc brakes until he started losing lots of races and finally relented for the 250GT series and the rest is history. The 250GTO and SWB won just about everything for a few years.
When Honda put the first disc on the CB750, I believe the effects were similar and this also set the mold for what we now see now as motorcycle racing.

true, but the CB had discs in 69......and the R90 is a pretty close choice for first superbike with its huge win at Daytona

no question CB750 was a ground breaking bike. come with one disc in 69. it did a lot of thing well and was affordable. but have never thought CB750 was a superbike. your mileage my veri ..

thought we were talking about the original superbike? Essentially every racebike/superbike now is an evolved CB750 with the obvious exception of Ducati and Aprillia.
