This is always a great topic, both for reinforcement of simply wearing good gear and ideas, thoughts, and feedback for new purchases. Type of riding for me depends on what I wear which I know is probably not hardcore ATGATT, but .........
Scura - Arai Signet or Arai Ram-X / Shoei / Bell Star, leather or textile jacket (Vanson MK2 perf, Revit, AStars w/ armor and back protector), some sort of reinforced kevlar jean, but I do confess to wearing plain old denim without my Bohn armor, AStars SMX boots, Sidi Doha, or other 3/4 boot with heel and ankle protection, good gloves . I'll wear the full on Vanson MK2 + pants if it's a multi-day trip. I picked up a Joe Rocket Survivor Suit years ago to commute in and use it depending on weather conditions and lower temps. It leaks like a sieve through the crotch, so fair warning you'll have a soggy taint upon arrival at your desk.
Africa Twin - Depends on temps and ride type. If I commute it's some sort of combo above or Klim Traverse jacket / pants, Sidi Crossfire's, Shoei Hornet.
Track Day - Haven't been out since early last year, but Pilot leathers have treated me well. I'm a tall, skinny guy so getting race leathers fitted properly is important and worth the extra $$. You don't want to go down in a saggy, ill fitting sack. I think more bits get hurt when you're moving around inside the suit as the suit is sliding and flailing all over the asphalt.
I will happily report that I've never been struck by a vehicle on the highway. I have been down many times at the track over the years and recognize that wearing the best gear you can afford at all times is key. It's unsettling enough to lowside or get ass packed at the track when you don't expect it. Can't imagine compounding that by placing the scenario into a busy intersection or highway.
