I sold him the bike. I mounted the takeoffs when I got the bike, they're both fresh. No problems with grip, the bike would pull stoppies in the rain. No issues with spin up on the power, either. The tires are fine, I've put 5k on a rear diablo supercorsa takeoff, including some more track time and a 3k mile trip on them, without any significant grip dropoff or problems. They had some minor tearing that I would have finished cleaning up before sale with a weekend ride, but he wanted the bike before I had time to ride it any more. Heat cycling of track tires is an anachronism with modern tires at street pace, having worn those exact same tires nearly down to the cords in the past and still having no slides or untoward behavior out of them. I had one diablo supercorsa go nearly a thousand track miles on my SV650 + whatever the previous person I bought the takeoffs from for the rear tire to go off at track pace, and even then it still performed fine on the street.
I have seen the tires, I mounted them, have ridden them, and they are fine for a novice rider to commute on. He'll wear through the rear in 2-3k, flat spot the front in about the same, and can swap them both out for a pair of nice fresh sport touring tires then. It's no better or worse than someone spooning on pilot powers to commute on.
Here's the original for sale thread, you can kinda see the wear on the rear tire:

They had under 200 miles on them, front and rear, when I mounted them.
Ok, the bilt is cheap. Thats its only plus.
Alpinestar or any major "overpriced" name brand is more protective and way more comfortable. Any disagreement on this is comical to me. That said, the bilt is better than a hoodie. But I personally won't be buying any bilt gear.
For a new rider, go buy some well armored, padded, and comfortable gear, consider a textile 2 piece. Knees palms and hips are first to hit the ground. Protect all of them, not just upper body. Keeping your entire body warm and comfortable while commuting will keep you more relaxed and focused. Forget the exhaust unless the current is damaged.
CE approved armor is CE approved armor. I've had A* stuff shred in accidents, I've had no-name stuff hold up fine...but the important thing is being able to wear the gear. If the Bilt stuff is comfortable and fits you well, that is far more important than the brand that's slapped on it. If gear is loose and can move around, it's useless, so buy based on what you'll wear first, fit is 2nd, CE approval is 3rd (armor doesn't do shit if it doesn't stay in place), and brand name is a distant, distant 4th. All the gear and brand recognition in the world is useless if it's hanging in your closet when you crash, or the armor rotates out of the way and leaves you exposed.
