I had an incident on the track related to that. Back end slid a bit and I instinctively stomped my foot, which then got promptly hit by the luggage guard and popped the back up a little. Luckily the boot saved me and I learned the same lesson that I learned the first time I rode a 3 wheelerAlso, the rear crash bars are commonly referred to as “ankle breakers” by LE motors guys too.
