Anyone know if you can narrow up the 12 YZ 450F? Thats the bike I have and its so bulky around the front shrouds compared to the new bikes. Any aftermarket companies that make parts to do this or has anyone rigged something up?

How much more narrow? I'd like it to be relatively close to the 250f if even possible

I have the Cycra shrouds which are suppose to be a bit narrower. But the difference is small maybe an inch. I am a big guy though so I actually prefer it being a bit wider.

My goal this winter is too narrow it up as much as possible, make it lighter, and alittle more powerful. So what are my options? I'll look at those shrouds. I'm a big time sledder, and it's super easy to drop weight off a sled, but what all can you get for a bike?? Doesn't look like their is much to do so with the bike. Also, any options for cams that add more power? Not new to dirtbiking, but new to modding bikes. Any suggestions are great!

Slow down there, skippy.

 

It's as narrow as it is going to get with Acerbis unless you make your own airbox and shrouds.

 

You can take the motor to any limit you want, but why don't you upgrade the pipe and the mapping first....cams don't help much unless you do head work too.

 

SteveThe ('16 WR) has installed the GYTR head and cams, a Big Bore kit, and pushed the mapping to the limit. 

I rode it before he dialed in the mapping, and it is a grunt machine that still revs. 

Truly amazing throttle response....

Monk is right

 

So how wide are these new bikes compared to say my old 05 steel frame? I've never measured anything but am always surprised at how wide the newer bikes look. Never understood the alum. frame thing for a woods bike.

It's all relative. I rode a co-workers '15 FE350S. It's definitely wider than my FX.
