I was wondering if anyone can give me some ideas for reducing the weight of my 2004 yz450f. Some have told me to get aluminum hubs to reduce 5 lbs.

A few things that come to mind are light weight wheels (hubs, spokes, and rims), light weight tubes, light weight axles, light weight exhaust, (Ti), Ti bolts, triple clamps.

This is mostly very expensive stuff. You'd probably lose more weight for less by purchasing a newer YZ.

The bike has aluminum hubs already. Dropping significant amounts of weight from the late MX bikes is neither easy nor cheap, as they just aren't packed with excess fat anymore.

Like gray said, trying to remove alot of weight on these bikes is gonna cost big bucks. But, if you're on a budget i would get a lighter muffler. Since the muffler is higher up on the bike it will be more noticeable when tossing the bike around. Not sure if i worded that last part correctly...

The newer YZ's are not any lighter than a 04. If anything the 10/11 gained weight. They do feel lighter when riding due to better mass centralization.

Been working the body and lost 12 and got stronger. Getting stronger was the bigger thing.....

Thought the hubs were cast that, at least that is what someone said. Seems like they should have been machined for balance.

The hubs are in fact cast. So what? Doesn't mean they aren't light. As far as balance goes, because of the relatively small diameter, an 8 ounce imbalance at the hub will have less effect than one ounce at the tire, and you don't balance your wheels anyway, do you?

Machined hubs are stronger, but the weight is fairly similar. I would recommend working out, like others said, and devoting a part of each ride to slow speed balance and precision. Doing this stuff gets your body in tune with your bike, so you can work together.

I recently picked up an '04 YZ450F and while it is somewhat heavier than my YZ250 smoker, the strong power more than makes up for the few extra pounds. People told me also that the 4Ts don't turn and I've been riding it in the woods, GP races and open areas and it's just a lot of fun. My only complaint is the MX suspension, which is too stiff for the stuff I ride for the most part.

I would worry more about dialing in the boingers and not worry about the weight. That is certainly the next thing on my list.

DO NOT try shave weight from your frame. There isnt really a cheap way to cut weight from a motocross bike other than carbon fiber and titanium...$$. Make sure your suspension is working properly, it has made a big difference on my 04.

Thanx MotorBoy and everyone else for the insight... may just wait for some more bux and look for a 2006 or newer 450f:p
and by the way does anyone know the benefits of upgrading the triple clamps
on a 2004 YZ450?
O:banghead: One of the ones I am researching has a pro-Pilot shock set-up and some high tech alloy triple clamps (applied triple clamp) which are allegedly 300-400 new along with a white bros exhaust

Good Replys, I have been working on my own weight and strength, the gear I wear and keeping the bike working in top shape. I think being strong makes the bike feel lighter. I dropped 25 lbs and the endurance is way up. I would love to see how light a KTM 350 is but the difference between a YZ250 and 450 still seems like a lot. Maybe the best combo is a modified 250 (285cc) lighter but with more power.
