I purchased a new 2012 WR450F in the spring of 2013 after selling my 2003 WR450, due to an injury I'm a little late posting this. I would like to thank the guys at Pro Moto for their help and for delivering a superb product. I had all these products on my 03 also with the exception of the dampener it was a Scotts. Not 1 product failed in 10 years of hard riding!
Remove the seat and rear plastic. Some trimming with an exacto knife and dremmel tool is needed. The Pro Moto directions are easy to read and understand, cutting the plastic is easy with the included templates!
It took me about 1.5hrs to install the rack and it's a durable handy little thing. It also adds a convenient lift point. Well it did on the 03, let's see how well this one holds up! lol
