07 YZ450F USFS approved?

I am taking delivery of my new 07 YZ450F this Tuesday. :ride: I traded my 06 WR250F. I was wondering about what I need to do to make the YZ USFS approved. I do not want to cause a fire this summer. I know I see a lot of MX style bikes on the trails and am sure that at least half of them are not set up with spark arrestors and other proper equipment.:thumbsup:

I saw a spark arrestor cone on the Yamaha website as an accessory for the YZ for like $35 or close to it. My question is can I get one of these and be o.k. or do I need a new slip on exhaust? I do not worry about the power loss too much because I am just getting off of a 250F so the 450F will probably kick my backside.

Probably have to get a ProMoto tip with an approved spark aresstor. Power loss, if any will be insignificant.

The cheapest option for a spark arrestor is a Pro Moto Billet or similar exhaust tip- the one on the Yamaha web site is probably for one of their aftermarket mufflers. That will get you USFS approved. You'll probably want to do more though- like handguards, skid plate, radiator braces, etc.

I have not seen a Pro Moto Billet unit before is there a website? I do plan on doing other things like the skid plate, hand guards, etc... as soon as my wallet gains weight.

white brothers aluminum pro 2 comes with a removable sparky endcap, adds alot a performance gains, rips...

Pro Moto Billet. Definitely go through the TT store for your purchase- great service and prices from my experience with them.
