I've been using various Motosportz products for a couple of years now and really like their radiator braces. They are light, robust, have a nice stand-off grille that does not impede air flow and replaces the factory louvers. I've clogged this grille with mud/debris and still not overheated as the brace's grille is spaced far out enough in front of the radiator to still allow air flow for the time being at speed. They swipe clean in a jiffy with a gloved hand too. I've also rock-tested these units. With the factory registers and tank covers in place the braces compliment same and if the bike lands hard enough on these units to damage them or the radiator I'll probably have other, larger issues as well. I've also tested them at altitude on tough alpine ST climbs starting at 4500' and ending at a lung scorching 8300' in mid-summer. No boil over. No drama. They fit, they work, the engineering/design is sound and the price is reasonable. It's a very simple design that simply works. Two thumbs up. Bikes used on : 2007 TC 250, 2009 WR 125
