Manual says to tighten that nut to 125 Nm......... Now that’s pretty tight + I don’t know how your supposed to get it that tight since as you tightening the nut that wants to spin the rear wheel.

Ijust tightened mine as tight as I could get it, folded the washer over and hoped for the best.

 

I tried again today with no success. Used a 6 ft iron pipe and no budgy. I made sure the washer was folded all the way back and I had it sit overnight in PB blaster. I guess I'll be taking it a auto shop with a 3/4" rattle gun to see if they can knock it loose, what a PIA

 

Put a bar or 2-by through the rear wheel across the swingarm.

 

I was unable to get the CS nut off even with taking the bike to local tire shop were they tried with their big impact guns. I ended up using a Dremel with a cut off wheel and carefully cutting through to the hollowed lip that is on the back side of the nut. Just took my time and did not damage anything other than the nut.

I found a write up on Dan Moore's site about cutting the nut off when I was researching the same problem.

 

Wow! first I have heard of any these nuts that were that tight.

 

The guys on the assembly line are waaaay over-tightening stuff on the new bikes in general. Wait until you take off your front wheel.

 

Spec is 90 ft/lbs. Some people have had no problems with "nearly as tight as possible with a normal 1/2" drive ratchet" and bending over a couple of tabs on the washer; makes it possible to do a field change of the front sprocket. 14 or 15 to cover some miles on roads; change to the 13 to play on trails. An idea for small displacement MC adventure touring; camping and exploring. Probably should carry a couple of spare tab washers along.

 

I have no real issues with my bike but my c/s sprocket was too tight and I have found other stuff ready to come loose, enough I have checked most everything on the bike now so I know I'll be ok miles from help.

 

Mine was on there really tight too. I finally got it off using a 1/2" breaker bar and a pipe, I think I kicked the end of the pipe to break it loose. It was a PITA. Too bad they didn't tighten the battery terminal nuts though I lost one of those when the bike was new.
