when I was very young I had a Triumph T21, All the kit on it, Swept back pipes, megaphone cans, clip ons, rearsets. I lived near the local bus terminal & left one day noticiing loadsa girlies waiting for the bus, I had to turn left right opposite the bus stop ----- & left my side stand down, At about 25mph I executed a perfect pole vault right in front of the said girlies !
