Did mine last month and love it! Did the gold color carrier though. I still need to sneak the scale out an weigh the stock bits.
Saving for a tune and pipe.

I would seem at least that amount. Stock bits are HEAVY!

What was the outcome? I'm looking to make the switch to the 41T.

Great mod for the money. 41t rear helps will acceleration of course. The lighter driveline weight helps the thrust of the bike.
Driving out of corners is much improved.

Here is a pic of the Gilles foot peg. Good grip. and 20mm lower or higher or back or forward. You can rotate 360 deg in increments. I have not put in the little plastic cap in the end as I had not torqued it when I took the photo.

Just did the 41T, 520, quick change, nuts, lightweight everything. The weight difference of the parts is amazing. It's less than 1/2 of the weight. Bike feels more nervous now but I only tested on highway. If I figure how to post a pic, I'll do it next.

Just getting around to switching out the rear sprocket with a 520 conversion.
I tell you that rear axle nut was bitch to get off. Air driven impact wrench would not budge it. Had to use about a metre of lever and took two people. One to sit on it and one to push the bar. I was surprised at how hard it was.
Have some new rubber to put on too. Two brand new SC1 front and back.

I used a Dewalt 1/2 Drive impact gun and it came right off. Had similar issues with my 848 like you describe.

I don't know what brand my friends impact wrench was but it was a 1/2 inch one driven by a small truck mounted air compressor that he uses to fix trucks on the side of the road. He could not believe it would not budge. Perhaps some get over torqued at the factory who knows. Maybe TJ99 who has something to do with Ducati may know.

The issue was probably the small compressor. They generally don't have to air flow needed for high torque wrenches or paint sprayers, things like that. The electric ones can be better in that type of roll.
Also try blasting it with a heat gun first. Especially if your bike has some miles on it. Mine came off using nothing more than some heat and a Harbor Freight electric impact.

The truck was small but the compressor was large and ran something like 150
Lbs.
I have done some weighing and it turns out less than half
Have not weighed the chains yet
Will do when I have both at the same length
Pulling the bike apart though exposes lots of area to clean

Shot myself in the foot. OEM front axle nut weighs 13.6g and the new CNC Gr5 Ti one weighs 26.9 grams. The CNC one is a little thicker in places and will be a lot stronger so will use it but just goes to show what little difference between the alloy OEM one and a Ti one.

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!

What a great idea. Probably have to look at getting one made.
My limit is making small custom Ti brackets just for fun. Changed some bolts over to Ti and just saved another 147 grams. Most of that was swapping out the Front calliper mount bolts which saved 100 grams.

I found one or someone pointed me to an alloy one made by TPO. Bellisimoto have them.

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 39 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.
