Front Sprocket Nut size

Does someone know the size of the nut on the front sprocket? I need to stop by the store and pick up a socket that fits it and I don't have my manual handy.

Thanks

I just replaced my sprockets on my 2008 Versys Saturday, the front was 27mm.

A 1-1/16" (26.9875mm) socket works perfectly.

I have a 1 and 1/16 12 point but it didn't feel secure so I didn't try it. I really need a 6 point I think.

Yes, that's what I use. A 1/2" drive 6 point 1-1/16" socket with breaker bar... The sprocket lock method allows use of a torque wrench too (92 ft-lbs).

I used the socket wedge trick and it worked but that sum-bitch was tight!!! Looks like the 14t raised the RPM on average about 500. I will know more tomorrow when I ride to work.

RPM will now be 7.143% higher than before (from 4000 to 4285.72, 5000 to 5357.15, 6000 to 6428.56) at the same actual speed in the same gear, but it won't change the tachometer to indicated speed relation. Speedometer error is now increased from about 7% to 14% over actual speed. Odometer/tripmeters which were near accurate before, now count about 7% over actual distance covered.

Yeah I was in a hurry this morning and forgot to mount up my GPS. But what you're saying seems about right based on the flow of traffic (typically 70 mph and I was showing about 80) this morning.

+1 - Use the 27mm as you don't want to take a chance on rounding the nut if the factory torqued it to 780 foot lbs! The 27mm is the correct size.

A 1-1/16" (26.9875mm) socket is even better than a 27mm. Make sure it's a 6 point.

Had my GPS this morning. 80 mph indicated is 70 mph on the GPS and I am running just under 5900 RPM. I am really liking this 14 t front sprocket. Gives the bike the get up and go I expected it to have in the first place.

After more riding I have noticed its pretty easy in 6th gear to use the tach as your speedo. 4000 RPM is 50 mph dead nuts as is 3000 RPM is 40 mph and 6000 RPM is 70 MPH.
