450 recently I had been to my cousin’s place I had to park my 450 in the basement. There is a gate inside the basment I had to stop n opened the gate which in in the basement it was steep down like down hill then side stand ans stoped untill I could remove my helmet after getting gown my 450 since it was steep it rolled down a distance of 2feet with the side stand open and the side Stang ght closed after the room and it fell had minor scratches and rear brake lever got folder. This is not the first time I felt about this rolling of my 450 whenever I used to park @ steep roads I was really disappointed when I found out actually rolls with the side stand and does not stop until it falls Since there was no handbrake in the 450 and it easily rolls down My suggestion to the ather 450 please get an accessory which helps 450 not to roll and stop in one place in simple words I would request to install a handbrake which would be helpful in the downhill or like a down hill assist
