The bloke on the bike is obviously wanting his 2 mins of YouTube fame and ironically makes himself look stupid because of his poor riding
Try passing your DAS before you criticise others....
As a motorcyclist too you need to be very careful about stopping like that and being rear ended. I didn’t see any lights on red - only green. Therefore what you did was wrong. If, like the picture you posted they’re on red - then that’s correct. Oh and do us a favour - don’t rev a 125 like that, it makes you look a dick.
Hope you sent this to the company!
