I rode on a plug for a couple thousand miles, but that's just me. Obviously it's smarter to replace the tire, but I commute daily on my bikes and didn't have time to run out to the dealer for a replacement for a while.
Had a nail on my tire when my 1199 "S" had 2,800kms on it...removed my rear wheel, had them remove the rear tire from the rim...pulled out the nail, had tire dealer install a cold patch in the inner portion of the tire where nail was.
I've done 2 trackdays and have put on many kilometers on it with
no issues. My bike now had 5,400kms and my rear tire will need replacing soon...not due to the repair, but due to it being worn out...
I've done it in the past even with 2 patches on the rear tire on my previous bike...not a problem. Depends on the puncture though...mine were small diameter nails. I just usually check the tire pressures from time to time. Now having
more than 2 patches on it...I may think of replacing my tire...
Tire will never blow...its tubeless...worse can happen is, the patch will not seal the hole well and you will get air leaking out from the repair...Most experienced riders can feel and will know when the bike handles differently, squirmming, wallowing or feels a bit sluggish, then they know its a soft rear tire.
Had no issues at all with repaired rear tires in the past.
