One thing with my differents bikes: Crash bars !
and also backrest with grabons for passengers.
I have slided 3 times in 20 years and these things save the bike and myself, they where slow slide mostly with no passenger at the time. The trick when the bike goes down was simply to hold on to the bike the closest way possible use the kill switch and slide with it until you lost enough speed and then letting go of the bike, leather is a must!
The bike simply slide on those bars and you don`t damage the bike unless the bike hit a bump or and object you just pick it up after and thank the Lord.
