What size is the nut on the front sprocket for the 1098S? Replacing the Sigma and renthal sprockets with a nice new shiney (and original teeth size) Renthal chain and sprockets MMMMMMM going to look sexshehhhh!!! ALSO! What size is the nuts for the rear wheel? Might change them over for something pretty looking.
Less than helpful answer - i dont know :biggrin: helpful answer - does the sticky above , workshop manuals, give you assistance ? just a thought TT
Ones bigger than the other! :wink: The wheel nut should be 55mm AF on a 1098, I'm not sure if the sprocket one is the same as an 848. Duke 1276 just did the sprocket on his 848, mines not here so I cant measure it for yer...but someone will be along soon who knows.
stole this lol * Lift the rear wheel off the ground and unload the rear suspension. I used a Pitbull stand to raise the rear of the bike and then lowered the fixed foot pegs on automotive jack stands. This allowed the rear suspension to be unloaded(full extension). * This step is optional- Measure the rear ride height and wheelbase(my preference is to measure the distance from the center of the swing arm pivot bolt to the center of the rear axle). Do this before any changes are made. * Remove front sprocket cover. Locate and mark the master link on the chain. Count the number of links if you chain is not stock length(stock length on 1098/1198 is 98 links). * With the chain in place, have another person apply the rear brake and stabilize the bike so you can loosen the front and rear sprocket nuts. You will need a hammer and a pin punch to release the locking tab on the front sprocket nut and remove the safety pin on the rear sprocket nut. A 36”(or longer) breaker bar will make this task easier. If you have a pneumatic impact gun then you can do this by yourself. * Locate the previously marked master link of the chain and remove the rivet heads. There are a number of suitable tools for this task but I used a die grinder. * Remove chain. Once the chain is removed take this opportunity to clean the upper and lower chain guide on the swing arm. * Replace the front sprocket and transfer the lock washer. Make sure the new front sprocket is offset to the same direction as the original sprocket. Tighten the retaining nut by hand. * Remove the rear sprocket and carrier assembly from the axle. * Transfer the carrier and crush drives onto the quick-change assembly, tighten the sprocket retaining nuts and install the assembly on the axle. Tighten the axle nut by hand. * Take the new chain out of the package, make sure the master link is in the package, and then cut the chain to your desired number of links. * Put transmission in neutral. Engage the links of the new chain onto the rear sprocket and carefully feed the chain to the front sprocket along the upper chain guide. Wrap the chain around the front sprocket and then connect the two ends of the chain with the new master link. Loosening the swing arm hub may make this task easier depending on length of the chain. * Press and rivet the master link with the proper tools. * Take some slack out of the chain by rotating the swing arm hub. * Tighten the front and rear sprocket nuts to factory torque setting. You will need another person to apply the rear brake and stabilize the bike. * Bend the locking tab on the front sprocket nut and install the safety pin on the rear sprocket nut. Reinstall the front sprocket cover. * Adjustment the chain to factory spec and then tighten the swing arm hub retaining bolts. NOTE: The sequence and methods of the steps may vary from one mechanic to another. This is the way I have done it, it may not be the best way but was definitely effective. Tools required: 32mm socket for front sprocket nut 14mm 12-point socket for rear sprocket carrier crush drive nuts 12mm 6-point socket for quick-change rear sprocket retaining nuts Factory rear wheel nut socket or equivilent Factory rear chain tension spanner wrench or equlivent Chain cutter or die grinder or drill Chain press & rivet kit 1/2"-drive Torque wrench 3/8"-drive ratchet and allen socket set Small hammer Pin punch or flat blade screw driver Torque settings: Front sprocket nut 186mn Rear axle nut 230mn Rear hub retaining bolts 33mn 1-2-1 sequence
It is a 55mm nut. I have just got nice new red nuts, no laughing, but am struggling to find anything other than an aluminium socket. When you look at the torque setting for the nut not sure an aluminium one will do the job. I think I am going to do what you are doing and change the whole lot and get Moto rapid to do the work.

I would never go for alloy....had a friends sheer off on his R1.Titanium If I was to change mine for coloured. just something to thing about
