Taming the YZ450 Beast????

34 posts in this topic

I am a new rider...I bought a 04 yz450f last summer. I usually ride trails and do ok. Recently I went to an indoor Mx short track and caked it 3 times mostly because of too much throttle at inapropriate times. Can someone tell me an easy way to slow down the yz450 and make the throttle more forgiving, at least until my skill and confidence improves? Would A sprocket change or different throttle control help? Thanks!

Get yourself a Dr.D 6 or 8oz Flywheel You can go with the heavier unit until you're more familiar with the bike, then swap it back for a lighter one later if you want. DRD will charge only for shipping on such an exchange.

Most people are happier with the early 450's with a 5 or 6 ounce (welded ring) heavier flywheel.

A heavier flywheel will definitely soften the hit and make it more controllable.

I reccomend Dr. D, as you can switch out weights for free.

Dr. D flywheel, gear her down one tooth, and pull that plug in your carb. . . at least that's what we used to do our '03's to soften the hit. . .

Hey, thanks everyone for the advice. I am going to give the track another shot before I mod the flywheel. Mostly because my friends and I are going in a few days. If I survive, and need to change I will definitely go with the Dr. D flywheel. I love me some body armour!

Respectfully,

Eric

I got the '03 450 as a first bike and now i love it but it took a few years. I softened the suspension, put a trailtech flywheel and got a more forward bar position. Now i'm thinking this thing is a dream and the tractor factor on H/S is a nice feature.

I am in the same boat you are. I just bought and YZ450F and got hurt before I could tame her. I have ordered the Yamha Heavy fly wheel $98.00 and will have my old one when I get used to all the power she has. I am also adding a Large tanks and full skid plate for the trail.

What does unplugging it do?

Im trying to tame this bike for a buddy who doesnt need all the power it has...ive already had him order a 10+ flywheel...

Buy a G2ergonomics throttle cam system and install a 10oz or 12oz flywheel weight. Check out G2ergo.com, this product really works.

TPS=Throttle Position Sensor...if you disconnect it, which is on the left side of the carb it will supposedly soften the hit. Do a search plenty of info in this forum on it.

In doing the search, you will find that disconnecting theTPS is a mod done primarily to 426's, not 450's. Go with the Dr.D 8oz, and if you still want less juice, buy a WR450 exhaust cam.

Tell me more about the G2ergo throttle. Do you own one?

As a 41 year old who returned to the sport after a 18 year layoff from Dirt Bikes.....

I say keep the bike as it is, and simply ride more, preferably open meadows, wide trails, etc. before hitting the tracks (especially smaller tracks). I purchased a 2004 Yz 450f, and I thought it was an animal also; I simply learned to manage the throttle more effectively, and learned to "grow" with the bike. At first in the woods I would stall it 5 or 6 times a day within a three hour riding window. Now it's an extreme rarity, and I'm in love with the "hit" and torque....in fact I'm thinking of going with a J/D jetting kit and a Boyesen Quickshot to possibly improve it's lower RPM snap. If you really feel intimidated, than by all means add the flywheel weight, etc. but for me, I think saddle time was the best cure.
