Wow that's brutal! Not that much damage though and sounds like the MOT centre were overall pleased with what you'd done to the bike. Yeah a few more hours of work but in the grand scheme of things I'd say overall plenty of positives to take. Most importantly, you're ok! Hope you can get it fixed it soon. Namaste. P.S. Plenty of Facebook motorcycle forums out there would be interested in all your content. Well worth searching a few out & posting some links imho.
Real pity about the brake lock up and damage. Glad it wasn't any worse damage to yourself. I'll be interested to know what you find in the braking system.
