The manual says to use an endless chain and remove the swingarm to put it on.
While this gives the opportunity to check/adjust/lubricate the swingarm/suspension linkage bearings most people don't want to go to this trouble at the same time as doing the chain but if you wish to this job too then refere to JBX's page here after the rear wheel has been removed.
Lets start.
You may wish to remove the exhausts (silencers not downpipes) to make access easier.
To get to the front sprocket start by taking the gear lever off by undoing the Allen bolt
then remove the plastic cover.
Speedo pick up cover to reveal the pick up sensor and rotor. And the gear lever linkage noting it's alignment on the shaft.
Remove the rotor (14mm nut), note the washer behind it.
And the sprocket cover.
You can then get to the sprocket and tab washer.
You will then need to place a chisel/screwdriver under the tab(s) and tap them until they are open (flat against sprocket) and you can get a socket (36mm) on the nut.
Undoing the the nut can be problematic, personally I use an impact wrench. If you don't have one it might be a good idea to have this undone at a local garage then just nipped up for a slow ride back to the house.
Once the nut is undone and removed go to the rear wheel.
Undo the nut
and slacken off the adjuster bolts (both sides)
and the caliper bracket slide bolt
You may also want to remove the caliper and tie it out of the way to make wheel removal/replacement easier if you are not experienced with this procedure.
As for the chain, grind off any two (I usually use the old soft link) rivet heads
and push the pins at least half way out with a chain breaker, remove the link and simply pull the chain through until it's completely removed. Now the chain is off you can remove the front sprocket.
Now remove the wheel nut and withdraw spindle, again this can be difficult if it doesn't get done very often so have a hammer and drift (copper or brass) handy and make sure there are no kids or pets nearby that might get hit by flying tools.
Once removed let the wheel drop to the floor and make sure you keep the spacers on their correct sides as they are different. Now you can roll the wheel back and push the caliper bracket forward and this will give enough room for the wheel to come out.
Remove the sprocket from the rear wheel and then take a break.
If you are anything like me, by this time there will be grease and black finger prints everywhere so take the time to clean up especially around the front sprocket area and inside the covers.
At this point it's a good idea to lubricate the wheel adjuster bolts and wind them in until the head of the adjuster is level with the front of the wheel spindle slot.
Now put the new front sprocket, tab washer and nut on and do the nut finger tight.
Put the new sprocket on the rear wheel and torque the nuts in a cross pattern to 69Nm and replace the wheel loosely.
Pass the new chain over the swingarm around the front sprocket and back under the swingarm, I find it best to have the two ends of the chain meet at the 2 o'clock position on the rear sprocket.
Put some grease and 2 'O' or 'X' rings (one on each pin) on the new rivet link and push link into the two ends of the chain, add the other 2 'O' or 'X' rings and the outer plate.
Now using the attachments of the chain breaker, push the outer plate on until it starts to squeeze the rings between the plates. change attachments and rivet the ends of the 2 pins.
Adjust the chain (50-60mm) and tighten the rear wheel (150Nm) and replace caliper if you removed it and tighten the slide bolt.
Now click into first gear, apply rear brake and torque the front sprocket nut to 85Nm, then bend tab or tabs as required.
Apart from reassembly of the front covers that should be job done.
Good luck.
