front sprocket x chalenge

[motorbike]

any one out there know the torque for the front sprocket nut....what is the standard amount of teeth and is it difficult to change same ....cheers

 

[JohnnyBoxer]

15t standard

Easy to change, if you have a grasp of spannering

Torque, can't remember though - 70-80 nM ish

15 t is standard but 16 t is much better for road use.

Very easy to Change and I wouldn't worry about torque just go as tight a a normal size bar/spanner will allow.

Oh and make sure the cup washer is the right way round!

Thanks ..read somewhere that you need to grease splines and locktight nut ...also can you recomend a good quality sprocket,again read that tourateck ones have worn out the shaft splines?....maybe reading to much info on a simple task

Does the shoulder of the sprocket go in towards the gearbox or out towards the nut?

 

[JohnnyBoxer]

Always use a BMW or Talon one

The others are sloppy on the shaft

Out towards the nut I believe, if you mean the side that's raised in the centre.
