I've embarked on doing a single nut rear axle conversion to my 6th Gen/5th Gen VFR825. Mohawk did it a couple of years ago and I used his ideas but ended up with a brand new RC45 rear wheel instead of the carbon wheel like Mohawk. (Yep, I got hold of a pair of RC45 wheels that a guy has had in a cupboard unused since the mid nineties) The donor axle was a VFR400 and so is the caliper, disk, and caliper carrier. Had to get the taper spacer for the wheel and a new nut and shim, from an RC45 via Partzilla and Tyga Performance. When I started, I could not find a donor VFR400 (NC30) so I used an axle from an MC28 but found that the MC28 axle is made from lower tensile steel and it's internal profile is quite different and I felt weaker than the NC30 axle. I would advise anyone doing this mod to use the NC30 donor parts and not the MC28. The cush drive assembly is based on a Ducati quick change unit from JT and I've used a set of urethane bobbins instead of the genuine Ducati SilentBloc rubber ones. In the end this has shaved 3.0kg off the unsprung weight on the rear. The assembly drawing lists all the parts used including the part numbers and suppliers. If anyone wants to go down the same route, I've made a full set of CAD drawings and these, along with photos, are below.

Your are good to go !

OMG!!!!!!! Phantom's build actually exists! Many :-)

Here are a couple of shots of the complete bike. Left and right.
