Drove by this scene on my way home from work. I'm pretty sure the bike was a Yamaha based on the red and white color scheme. Looked like an early 2000's R6 or R1.
The front wheel and forks were still wedged under the guard rail on the outside of the turn. The rest of the bike was on it's side a number of meters farther up resting near the guardrail. There were no other vehicles stopped (other than a bunch of cop cars) So I assume it was a single vehicle accident. Actual facts may be slightly different. I only know what I saw.
