I'm not sure what Zip-ty has planed, but their link sounds like it only lowers the rear of the bike. I dunno bout other peoples wr450's but on mine There is NO fork ajustment available. I measured from the top of the tire to the underside of the front fender and it is right at 12". Seeing as the fork has roughly 12" travel, I see it hard to lower the front end by moving the forks up in the clamps. The tire will hit the fender. That being said, if you only lower the rear you are going to Fock up the handeling of the bike. Although it will decsend steeper hills better, I don't think that is what people are after. I wonder what they are doing about this? Also companies like Devol that lower the bike 2" !!! How are they doing it? Unless there is something I am missing, They would have to cut your fork travel by 2" to not hit the fender and bottom tripple clamp, thus only giving you 10" or go to a 2" smaller front wheel( &%$#@!!?) . If this is the case, Bad Idea in my opinion. But maybe its worth it for shorter riders. Also you loose a lot of ground clearance when you lower the bike. For Nasty riding, logs, moab, etc. type riding the high frame clearance of the WR is second to none. Yes it is a little top heavy, but there are other ways around that. I will be shedding 30 lbs or so of weight off my WR by removing stuff and fabricating a few parts. Being 6'4" I can flat foot my wr450 with my knees slightly bent, but I know that doesn't help you guys any. I feel for you guys. I guess I 'm just trying to say look at All aspects of this to see what is best for you. There are always compromises, just find the best one that doesn't screw up your enjoyment of riding.
