I am signed up for a moto bicycle race referee class next month. I moto supported Levi's Gran Fondo, 2800 riders back in Oct and I guess I passed the good ole boys test (CHP and other LEO bike retirees are the vast majority of the moto refs) cause they made sure I got hooked into the classes etc. Hard core slow riding skills and 360 degree sit awareness needed. Try essentially idling a 650lb BMW RT up an 18% grade on a road with no shoulders about 30 feet wide surrounded by out of the saddle hammering riders on the edge. Can't go faster, can't go slower, and cant ride anywhere but 6" from the left end of roadway. Trial by fire baby! One perk is no centerline or speed rules for the guys in the "band". I rode back to the south bay from Santa Rosa with a long time moto cop and then moto support guy. Never stuck his leg out, followed every rule of the road except the speed rules but even then never faster than the flow of traffic etc. Learned a ton. In the twisties on a big GS BMW moving his body was not necessary in the try for sure. Super smooth and fast.
Oh by the way, want to test your slow speed and tight quarters skills then split lanes north bound during evening rush our on 19th ave through San Francisco and onto the Golden Gate Bridge on a big bike (I left the side bags at home, did topcase and backpack). Will save you 20 minutes or more but you may need to wash your drawers! I can't even commute with the side cases on the bike anymore. I would be a menace bumping peoples vehicles.
