time and experience is the answer
I've trashed many a bike, surprisingly most not my fault. It takes some time, and i agree, the course is a great way to "get back on the horse" . Every time I have gone down, you are changed a little, not scared, but more observant. I scan intersections allot, at night, I actively look for the deer, rather than passively. I scan my rear views at lights, while the bike is in gear. Each time I learn from the previous accident, and incorporate lessons for the future. I do this almost subconsciously. Its still amazingly fun for me to ride, and i'm a better rider for it! It is taboo, but here is a timeline of all the scoots, and their outcomes. as you can see it gets better with time and experience.
1971 yam 200/2 stroke more time down than on the road- oil injectors screwed up, would seize the engine all the time, lotsa fun at 60MPH, squared off the tires on that one!
1989- 16 YO with her licence 20 mins, coming back from the DMV took out me and my suzuki savage in Syracuse ny
1990's killed a couple of dirt bikes while showing my ass
1978 Yamaha xs750 triple on some ill prompted off roading
seccaII 650 mostly up, but sometimes not- 7 tickets on one stop for this one. pissed the cop off good.
2000-intruder 1400 hit some sand and went down, no damage just embarrassment
1989 FLHT dumped a few times in parking lots
2006 FLHX dumped a few times nothing major
2011 ultra classic limited- never down
2013 F6B never down - knock on wood
Good luck getting back on the horse, don't take too long and don't let the fear overcome you!
