I recently noticed that the grips on my '11 GSA were getting really worn and had just started to peel apart slightly. I've only done 12500 miles on it and would have thought they'd be more durable. However, thought I'd do something about it before it got much worse and here is my solution.
Firstly, I bought a couple of cricket bat handle covers off ebay for £5 including delivery. They're nice and thin as I like the diameter of the original grips and didn't want to make them too thick, also wanted the heater element not to be too insulated either. One regular rubber handle would in theory be long enough to cover both grips but you'll see why I bought 2 - the application process.
This is how my grips looked before, not too bad, but won't improve.


These are all the tools you'll need:
Cricket bat handle covers x 2
T55 Torx bit + ratchet
Scalpel
Non oily lubricant
Rubber solution glue (Optional)

Remove Torx bolt from handlebar end along with bar end weight.



Next turn half of the rubber sleeve inside out as shown below.


Next pour some lubricant in between the two rubber surfaces so that they will slide against each other when rolling the sleeve on to the handlebar.

Now get the sleeve started on the end of the bar as shown, then roll the sleeve on toward the centre of the bars.

)


All you have to do now is wipe everything off, cut off the excess very carefully with a scalpel and reassemble. I glued the sleeve to the grip on the bar end for added security with some contact adhesive. Not sure how long it'll last but it's not the most onerous of tasks and only takes about 10 -15 mins a side
