Straight in, no messing, don't know what all the fuss is about!
I wanted a 6" rear wheel and to loose the torque arm (hate the look of them). Purely cosmetic.
Well, ahem... Took about 5 hours in the end!
I had an r1 rear wheel with no disc/sprocket but otherwise in really good condition. Firstly, the discs are not swapable, so I got an old rusty R1 disc, sorted. I also got an R1 rear caliper and hanger, after eyeballing the swingarm it was my intention to weld blocks above/below the R1 hanger to mimick the way the R1 is setup to capture the rear hanger block.
Rusty disc, waiting to be skimmed/cleaned
Popping it all in the fazer today though this wasn't going to happen because on the R1 wheel the disk is waaay inside the wheel in comparison to the fazer, this meant the hangar is about ( well is in fact, 18mm ) off the swingarm, the blocks would have to span this gap, not great.
So, plan B was to weld an extension onto the R1 hangar and attach it to a pickup on the inside of the swingarm.
So, first things first, make the extension. Here we see it in the final stages on the 6-axis CNC milling machine. This is currently opening the slot that the pickup will ride in (essentially the front end of the torque arm).
This is how it fits on the R1 caliper hanger.
TiG Welded in place.
Prepare to be bored..ed?
Setup to start boring out the extension to fit the spindle. All CNC of course.
Action shot, spinning...
Done, Recess is there to accept a press fit spacer that will take up the extra 6mm or so on the right of the hanger (18mm total gat, 12mm plate = 6mm to fill.
Because you don't want spacers falling all over the gaff this will be pressed into the recess and be pretty much a permanent fixture, nice.
Dry fit, this is how it fits on the swingarm, the slotted torque arm can be seen, the pickup (or stop) has been tig welded in place here, all fits perfectly.
So, all fitted
Much more gentlemanly
Ran out of time a bit (had to rush home to take the missus to work, so really I need to take all this off and paint it as its currently bare ally.
But, riding it home it felt great, just the same as with the std rear.
