So on my way to work this morning I am turning right at a traffic light when the car in front of me suddenly stopped to let an ambulance coming the other way by (no lights on). I didn't have time or space to get the bike upright and handlebars straight before I stopped so down she went. ...
The only other time something similar happened was when I was taking an MSF class and practicing an e-stop in a curve. The drill is to brake, and just before stopping straighten out and get the bike upright. Easier said than done...
Jim it looks like you had a couple of issues contributing to the drop.
First, you were following too close to the vehicle in front, and had no reactionary gap to allow a proper stop.
Second, you are incorrect on the MSF procedure. What we brief is to quickly get the bike upright, bars square and THEN apply both brakes fully to stop. In the new material the use of trail braking is introduced so people understand that some braking can be done as you get the bike upright. Again, practice in the skill is important, because it takes a find touch to do it properly.
The reason you dropped your bike both on the BRC Range exercise as well as your bike, is that you were applying the front brake in the turn and it levered the bike over hard as it lost speed.
This is the usual reason people drop big bikes maneuvering in parking lots: They touch the front brake with the bars turned at very low speeds with the resulting crash. Once it levers over you cannot stop it in most instances. Stay off the front brake at low speed with the bars turned. Only apply the front with the bars square front tire straight ahead.
FWIW, I was once riding my okd R1200RR around some very tight radius blind curves at about 20-25 mph and maintaining my lane. On on particularly tight 180 degree left turn, as I am looking through the turn and leaned over about 30 degrees, my eyes behold a huge combine with the harvester knives up about chest high aimed at me ! I did the MSF quick stop in curves which I demonstrate regularly and came to a controlled stop, on the asphalt, and stared hard at the idiot sitting in the road on that thing. He said "I guess I need to move off the road huh? "
Emergency skills we teach work when you need them but have to be practiced regularly because there are volatile skills:
1. Quick stops straight ahead.
2. Quick stops in turns.
3. Emergency swerves.
Might I suggest that you sign up for another BRCII where you can ride your bike and see how it reacts, and then the new Advanced course which will show you what the bike can do at some speed.
Hope you heal up quickly !
