2008 YZ450f Steering Help

29 posts in this topic

I have a 2008 YZ450F and the cornering is not the best. It seems like I’m constantly fitting with the bike when cornering. I was wonder what others have done to improve their 08’s to steer better. Right now the bike steering is stock.

I have seen Dubach Radiator lowering kit, but you need to replace the header for clearance. I can see maybe replacing just the header, but not the entire exhaust. Can you just replace the header which provides a lower bend, like for example an FMF Header-Bomb and have it work with the stock muffler and the Dubach kit?

I have also read that you can change the top triple clamp, but not sure which one would be the best offset to choose from to improve cornering.

Thanks,

Emxdad….

Change the front tire, make sure the triple clamp is lowered to the first mark and set the sag at 95-100mm. Thats a good start.

There is no easy fix for this problem.

Yamahas are not known for their nimble turning abilities.

good front tire (12 PSI), plus dropping your fork tubes in the clamps 10 MM, bar position, race sag , proper suspension settings are needed front and back.

even then the front end will plow into turns.

what i have found is you have to allow the bike to slide into the turn a bit and gas it hard to come out of the turn. don't let the bike ride you.

speed is key. turn with your back end as much as possible. also look further down the track with your head. the bike will make the turn. faster you go the easier it is.

In addition to the rest of the advice so far given, move the bars up and forward, and move yourself as far forward as you can get.

depends on your riding style. i dropped my bars back. i found that getting up on the tank too much caused the front end to wash out more.

check out J Law's set up. Bars back. back on the seat. sliding the back end around.

Jlaw is a teenage stoner.

Check out Dr.D 's style. (just the opposite) He's crashed fewer cars, but won more championships. It is true that if you can get the rear out going into the turn and stay on the gas some, the front will push less.

There are different times through the vid that he does get way up forward for high speed turning...The times when he flips the back end around he's almost coming to a stop...Just coming in hot, shooting out hot, but it's not really a high speed turn...

hmmm.... interesting. here are a few videos of top riders turning on the YZ.

i think everyone should take a moment to watch them and discuss.

I think the vids just solidify my point...If you watch them in high speed turns (as opposed to high banked, hard braking , fast accelerating turns) you'll see their weight shift forward...

Studying James' style will get you nowhere in real life...The best riders in the world don't even bother trying to mimic some of the stuff he does...

In the real world of a middle aged 200lb rider, sliding forward and having body positioning similar to Dr.D 's in the pic above will help...

i like the feeling of the bars in my lap when i am slid forward. arms relaxed, pushing on my outside peg. leg kicked out, right at the low point in the seat.

then i get my weight back as much as i can out of the turn so i can maximize my traction.

i am also 5'10 but close to 200 with gear.

I know what to do I just don't do it!

In the current issue of dirt rider, or maybe it was dirt bike, there is a article on Ryan Hughes and his new rider technique. Un hinge the hips or something like that. Interesting, so elbows up are out.

Back in the day Dick Burleson ran his bars low and back. Won't see that these days. Moral, it's allways changing. Make it what works for you.

+1. Could not have said it better. I tried 23MM, 22MM and 17MM clamps - no improvement beyond doing everything Clutchless says above. Once you get comfortable drifting a bit into a corner then getting on the gas you will notice a huge improvement, and looking way ahead helps you do this.

hi,

I tried lowering the radiators on my (yzf450 2009 with a drd exhaust ) bike myself, but I had a problem. On the right side the radiator doesn't want to move down because of the radiator hose.

did anyone ever have this problem? what can i do?

You guys are missing the biggest part of that drd pic. his head is over the bars! it does mater where u sit but u HAVE to have ur head over bars looking forward. basic riding technique. sliding forks up does help with tight turns but like other people have already said, after awhile u will get used to it sliding. be glad u dont have a honda! LOL talk about pushing!

Not all of us are missing that:

Guys I moved the forks up 10mm and the cornering on this bike improved by %100 in my opinion. This was a cheap and easy fix for sure! Next change will be to replace the stock front tire.

Thanks again to everyone!!
