I think the point of the Rizoma one is that there is more sticking out further on the right side than on the left. So, on the left side their normal frame slider would take most of the damage, but on the right side the frame slider alone wouldn't provide the same level of protection.OUCH! I guess they will work well for a tip over, but god forbid you crash at any speed - they would just be shredded off...
OH well - at least they cover both sides... The Rizoma lower engine guard only covers the right side - nothing for the left side. I guess in Italy, people only crash on the right? WTF?
