I think its ST842 and I got them from Shift Tech. I ended up removing the extension as it made them stick out more and clashed with my left boot trying to get the side stand down.

I have just bought the Mag 1 boots so maybe not a problem. You will find them no problem on the shift tech web page. They are expensive though.

cheers

Some weights from the 520 Conversion.

OEM Chain = 2099 g 520 chain = 1865 g
OEM Hub Cover = 349 g CNC = 312 g

OEM Cush drives, OEM Hub cover sprocket and nuts = 1550.3 g
Light weight polyurethane cush drives with light carrier and sprocket = 887 g

OEM Front Sprocket = 251 g AFAM drilled Front sprocket = 178 g

OEM Rear Steel 530 31 T = 1201 g AFAM 520 41 T Alloy Superlite = 197 g

OEM Rear Axle nuts(2)= 229.6 g CNC Ti x 2 = 138.5 g

OEM rear sprocket nuts = 61.6 g CNC Ti = 35.6 g

OEM Air Filter with brackets = 291 grams MWR new Race Filter = 177.7 g


Unfortunately the lovely CNC Ti sprocket bolts are a different pitch to the Polyurethane light cush drives so I have now ordered a set of Pro Bolt nuts in the correct pitch. Just have to put the hugger back on and one lower fairing and ready for a test ride. Rain forecast tomorrow so maybe no test ride. Bummer.

Nice weight savings! Look forward to your review after your ride. I plan to do the AEM 520 setup in the near future.
 
Some better photos. Today I rethreaded my CNC Ti nuts to fit the Hyperflex polyurethane cush drives I got. You can see the red polyurethane in photo number 2330. The gold coloured nuts on on the sprocket are from Pro Bolt.

I did to know how to attach larger photos into a post so have used dropbox links. Click on the links for photos. The files are big so takes a few moments to load.

That aluminum axle nut is probably the lightest piece of large hardware on the bike. Thanks for weighing these. Are you aware of anybody that makes a Ti front axle for the 1199? That would shed some serious unsprung grams! :)

I bought one for my 1199 off of eBay - came from Italy.

Damn that's pretty.
 
Curious. Im having trouble following the re-threading of the nuts to fit the cush drive. Different thread pitch? You could not find nuts in the correct thread pitch/size? How is the integrity of threads cut over existing threaded material from a torque value perspective?

mate that was a while ago and a few kilometres and nothing fell apart.

I had the same concern so watched it carefully. Ti always torques a bit less.

Yes there was a difference between the cush drive studs and the CNC Ti nuts. I posted about that to warn people. 1.25 to 1.0.

It meant losing about one half turn of thread. It has not been an issue. Since then bike has had full power runs on dyno and not a problem. And lots of street riding and one track day.

remember the stress is not in the same plane.

Sometimes I think people overthink these things. If it works it works. And it seems to be working.

I recommend a book by Tim Hanna called 'One Good Run. The Legend of Bert Munro.' Gives you a new perspective on modifying motorcycles.

BTW endodoc. Always enjoy reading your posts, looks like you're someone who has a go.

sorry forgot to add I had some pro bolt nuts that were same thread but looked .... compared to the CNC.
 
Thanks for the kind words. Good to hear everything is working well. Bike looks great. Hope to get down that way this summer.
