Hi "D"..... I have 2 covers. 1 is a 1/2 cover from Nelson Rigg size medium and fits like a glove. Good to travel with or take to work if it sits outside. Does not touch the hot muffler and is waterproof. My 2nd cover is a full cover for home.... Guardian weatherproof in size medium which also fits wonderfully well and taunt. Have had this one for 2 years and still does not need replacing. I do use the 1/2 cover more often around the house because it is so easy to whip on and whip off. If weather is inclement I just put the full Guardian overtop to keep water off the bike's bottom. (the 1/2 cover pulls over top of the muffler if you want to keep rain out).... I like them both and they fit the pregen and "now gen" very well.
