I fiind myself cursed with the "beakish" Generation 2 front fender that is fabled for creating handling issues at high speeds (above 70mph) due to its design acting as a "kite" or "sail." A lot of riders consider it a drawback to the Gen2 KLR "makeover" and consider it a nuisance if not an outright danger.
It seems like a lot of riders opt to forego the stock front fender entirely, replacing it with front fenders from other motorcycles. While doing research, I found this effective solution online: the "Kawasaki KLR 650 Generation 2 Front Fender Laminar Lip." I figured "What can I lose for $25?"
I was able to get it installed over the weekend and give it a try on a windy day and the difference in handling was immediately apparent and much appreciated. Gone were the days of sudden and unexpected movement of the bars, bike and myself as gusts of wind or the wind blast from semis caught the oversized and poorly-designed stock front fender.
When I first received the thing in the mail, I thought, "What the hell is this gonna do?" It didn't seem like much and I had my doubts as to its efficiency in alleviating the problems associated with the fender's poor aerodynamics.
The lip itself is made from .040 aluminum stock and is easily attached, requiring only the drilling of two small holes in the fender to use the included screws and nuts. After I had installed it, I couldn't resist pushing on it and, just as I had thought, it seemed suspect and flimsy. It currently only comes in black, but can be painted to match fenders of any color.
The manufacturer claims that the laminar lip disrupts the "Boundary Layer" that forms just above the surface of the Gen2 front fender at higher speeds, especially generating lift in the recessed area at the flat, top part of the fender near the attachment point where the fender is beefier and forces can be transferred through the forks.
With the boundary layer disrupted, the molecules of air don't get a good "grip" on the material they're passing over (in this case the upper surfaces of the fender) therefore the forces of any air molecules (i.e. "wind") impacting and flowing over fender and creating lift are greatly negated by the laminar lip disrupting their flow.
All the technical mumbo-jumbo aside, the proof is in the pudding. I put this thing on and can confirm that it does work and, in fact, works quite well. Freeway riding and riding on windy, gusty days are much more relaxed and also much safer. Thanks to this laminar lip, my "Front Fender Of Death" is no longer a concern. I recommend the product highly. For those of you concerned about the aerodynamics of the stock Gen2 fender, the laminar lip is an economical solution and is a lot quicker and easier to put on that a complete replacement fender.
