Thanks for the web link, Abraham. I'm finding it would be more useful if they also had the swing-arm attached, but I shouldn't be fussy.
OK, so what better things to do on a windy, rainy Perth September morn, than to draw ideas for my next bike
I have two ideas in mind - one bike that can be built fairly quickly using a pre-existing frame, and another that will be scratch built. The former will use a GSXR1000 chassis, as this seems to be the most spacious frame I can find. They are also fairly common. The bespoke frame, one where the motor is right at the pivot point, will take some serious thought, but will eventually result in a completely Japan-independent motorcycle. One for later
My friend Antti was kind enough to bring his old Gixxer frame to Winton so we could take some pictures and take a few measurements.
The battery pack I have in mind would be one hundred and forty A123 cells in series, using the opposite stacked method described above, but with two of them side by side. It makes for a 72 kg block, so a winch would be handy to put it in and out. This block would be about 300 mm wide and 360 mm long, and fit inside a Gixxer bay without too much trouble.
The motor would be slung as low as practical, and since the AFM-130 from Evo-Electric is a narrow motor, you can do just this. The reduction drive will take some thought, as there are not many points on the motor where you can bolt a driven shaft. I figure a chain would do reasonably well, and no doubt easier than a series of cogs, stealing power with each rotation. This bit of engineering will be my next project, as I can also use the outer casing of this to invent attachment points for the new stressed member (I was thinking of laser cut ally plate, but no doubt something can be welded up easy enough).
Just got to get the race-prepped bike ready to rip out all the IC bits
So if anyone has a mid 2000s Gixxer race bike they wish to retire, let me know
