I've got a 2piece Dianese suit. It works well not crash tested, top is not stand alone to be used as a jacket because it is too short for that. Used to wear acustom IM lethers suit for roadracing in 84 and 85 crash tested that one. Like the amount of protection with the armour in elbows knees and shoulders. Also get a Dianese back protector and wear it...always even on the street. Dianese gloves work well also. Shoei Eddie Lawson special. Love steady Eddie. Hope this helps.
