Still to answer the statement above when put under the dealers PC we see to many issues and faults on bikes with batteries over 3 years.
Erasing them delets the issues, stil, that doesn't mean that the bike performs as it soukd, its the case of simply not being noticed by the rider,  the bike needs diagnostics .

My supplier is using led OSRAM and PHILIPS products.
All without issues for a canbus.
For exactly 8 years of use in my K bike, no issues, ofcourse they were not bought from Amazon etc..

The battery on any K bike is always connected and in such state the time llimit is two years.
Some fortune ones had batteries that lasted more , still the change mark time is two years.
Try a Li Ion battery from a good brand and the new battery will be an issue every five years, bear in mind that for the first 7 minutes every time your shifter will be intolerable and not performing changes , this for K13 bikes, after that youre good to go. That issue with this type of batteries is causing a thousand gremlins in many brands and many bike models espacially those over 600cc.

Never liked it ,  not even worth any comments .

The deep and detailed knowledge aquired for K bikes is astonishing.
Still its a bike we love but a bike old, and comparing it only encyclopedic knowledge offers.

Am with Tom , needs to come off.

That's what the strake bars are for. M25 filtering I think.

They are actually there to secure bike from spinning in case of a fall after both low or high sliding.
