I started jumping and need serious suspension advice

I moved to Mazatlan, Mexico this past month and have a nice super cross track 2 blocks from my house. I had done minor jumping before but nothing like the doubles I´m starting to do now. When I land them smooth then I´m fine but being a new rider, I often miscalculate and am finding that these suspensions are way too soft for serious impacts. The rear shock isn´t as bad (although it rebounds like a pogo stick) but I constantly bottom out my front suspension. I weigh about 185-190 and ride an ´04 wr450. The guys at the track said the suspension is designed for sucking up the chatter and smaller bumps of trail riding but that the tradeoff is that it can´t handle the big slams of a supercross track. Is this accurate?

What is my best option to set it up to handle the track but still handle reasonably well on the off road circuits they have all around me down here? Parts are scarce but I´ll be heading back to Arizona in March and can take the bike somewhere if necessary to have the suspension tricked out. What are my options for say $500, $1000? I don´t want to spend anymore than I have to but I´m getting addicted to the track and am sketched jumping any doubles over 25 feet as I´ve slammed the front forks really hard on a few bad jumps.

Thanks for all of your guys help! BTW the riding here is unbelievable (as well as the surf) if any of you make it down here.

i got mine done for $250 and haven't bottomed out yet jumping 40/50 ft. if you were in cali i'd give you the guys #. for the back end bounce try clicking the adjuster down alittle... maybe 2 clicks from where you have it. i'm running 8 clicks total all the way around with the back shock ajusted half way down the threads.

For $1000 you coud get a 2nd bike just like my old cr. :p
You definetely need those springs for your weight and maybe, just maybe with just that and some clicking you wont be so mistreated by the wr. :cheers:
Hope to see you soon at the track again.

It sounds to me that you need another bike, WR is by no means a Supercross bike.

If you definately wanted to keep the WR for some reason or other...I would suggest either getting YZF springs or replacing your stock springs now with after market/get a valve job but that can get costly. The cheapest way would be to start adjusting the forks either soft or hard on the top of the fork itself. Play around with the stock stuff and you might get it how you like it or close.

The idea of a second bike has crossed my mind but I actually love how my WR performs all around on trails and even on the track with an exception of bottoming out. I´m going to play around with the adjustments a little but I´m not sure how much difference it will make since I seem to be too heavy for it.

What are the chances of blowing out/damaging my suspension riding it hard with the current setup? It may be psychological but after I undershot a decent double the otherday and drove the front tire right into the face of the double it seems to bottom out even more. Maybe I´m imagining it but how do I know if something was indeed damaged? I don´t see any oil leaking.

If I end up riding the track more I´ll probably have to consider another bike but won´t get rid of my WR no matter what. Aren´t some guys racing the 4 strokes now on supercross? I thought RC won on a Suzuki.

Thanks again!

I think all the ones who qualify are on 4-strokes now.

Yes most of the guys race on 4 strokes but on MX bikes like the YZF250 or YZF450.
WR are 4 strokes trail or enduro bikes.
And finally Yz250 and YZ 125 are MX 2 stroke bikes.

You can also ride a MX bike in enduro or trails by changing some stuff or even ride them stock. It´s just a tradeoff for some things like suspension, gearing, top speed, weight, traction, etc....

I had your exact problem. I got a wr250f for trails and hare scrambles, but started to spend all my time at the motocross track with my kids. I had done all the free mods, put on YZ250 exhaust, JD jet kit, etc. What I found on the track was that the soft suspension and the wide ratio transmission was killing me. If I didn't land perfectly it was like hitting a wall and I was either racing the engine or lugging too big a gear, I needed gear 3.5, etc.
My solution: Trade it in for a 2006 YZ450f. Its the best thing I have done in a long time.

I guess I should have done a little more research before buying. I thought YZs were 2 stroke and WRs 4 strokes so my main question was the 250 or 450 as I knew I didn't want a 2 stroke. It sounds like the YZ450F would have been the better all around bike for me unless it suffers on the trails.

Well, I love trail riding as much as the track so that aspect of the WR I love. Also, I have no intention of racing motocross so as of yet, even the wide ration isn't killing me that much on the track. My main issue is the soft suspension. I guess what it comes down to is will I destroy this suspension by jumping it or is it just going to beat me up more? If I put in stiffer springs or take the bike somewhere to have the suspension dialed will that take care of my jumping issues? That is what I was referring to when I threw out $500-$1000 as I thought I read someone posting that they had their suspension totally set up by some company and it cost maybe $500-700.

I'm just trying to figure out if spending a little money will make the bike adequate for jumping on the track while keeping it sweet on the trails or if I'd just be spending a bunch of money on the wrong bike when I should have YZ450f or something else. I'd appreciate some comments on the pros and cons of the WR and YZf on track and trails.

I have an 05 WR 450 and had to replace the fork springs right away due to severe bottoming off jumps. I went with the Race Tech .48 fork springs. I weigh about the same as you. It made a tremendous difference and no more bottoming. Might have to play with the clickers to fine tune, but overall happy with just a spring rate change

Just spend the $200 for springs front and back (total). This will make a huge difference. Go to racetech.com spring calculator and pick out the right springs for your weight. If you are in between spring rates, go to the next heavier spring. Or, if you've got the money to spend, take your forks and shock to a good suspension shop for springs and a revalve. Now go ride, you're just having fun and you've got a great all around bike for it.

It sounds like you really do not want to spend the money on a different bike for the track. The ideal solution is to have a track bike for the track and a woods bike for the woods.The two are too dissimilar to have one dialed for both....but you can get you WR to perform acceptably on a MX track. You should start with springs sized for your weight....that will help with bottom resistance.A re valve can help some with bottom resistance also.If you put a set of air cells on...that will add plushness AND bottom resistance(best mod I've done to mine:thumbsup: )and do it in that order.In the rear get the spring first for your weight then a re valve if your still unhappy.You should also try to learn everything about tuning possible.Those clickers can make a world of difference to the way your bike rides as well as the oil level in the forks ,springs ,preload,type suspension fluid etc.Even if you have your bike re valved professionally ,do not be surprised if you still need to change something to get exactly what you want. I'm not trying to slam anyone but you only have about a 50% chance of getting a good re valve IMO. Who ever you choose should be reputable and well known.Do not choose on price alone.The cheapest tuner is the one that will just change your fork oil out:busted:
It takes some work to get a bike to work good but it will repay you with a plush ride with more comfort,more control and hence less crashes and more speed !!!!!!:cheers:

Ok, I´m starting to feel much better now! Yes, I have the money to buy another bike for the track but it´s one of those things where I´ve got so many hobbies and know that I´ll probably get tired of the track once I´ve ridden the same one day after day. I have no desire to race and though I guess I´m still kind of young at 33 years old, I don´t really want to get too crazy into motocross as I´m already starting to get aches and pains in areas I never did before and that´s without having blown out a knee or wrecked my back like so many racers I know. I´m just hoping to get my bike dialed in to where I can have fun at the track and still enjoy all of the great trail riding Mexico has to offer.

That being said.... how difficult is it to change out the springs myself? My sister is coming down in a few weeks and could maybe bring me the stuff if I ordered it. If not, I´ll have to wait until I go back to the States in February which would suck since my bike feels like I damaged my suspension. It might be psychological but I swear my suspension feels twice as soft as it did before I bottomed out a few times on the track so even trail riding doesn´t feel like it used to. I asked this earlier, how can I tell if I damaged something? I haven´t seen any oil leaking out of my forks but I haven´t checked my shock and it feels really soft. What do I look for?

So besided new springs, what else will I need? How would I find a good suspension shop in Phoenix, AZ when I go back if changing out the springs and revalving is too difficult for me?

Thanks again guys and it sounds like I might be able to dial this bike in after all. Man, it sure is fun on the trails!:cheers:

You definetly need to check out the suspension forum but just to throw out a couple of ideas,

1) Raise the fork oil height. This will improve bottoming resistance.

2) If you REALLY need stiffer springs but can't afford the $$ cutting your current springs will raise the spring ratio. Takes some technique, works best for rear spring (front requires spaces), but it's cheap.

3) You should be able to rebuild the stacks your-self. Parts are cheap (just washers after all) but you'll need to pick someone's brain to get a good stack to start with.

For cutting springs see this web article: http://dirtbike.off-...l.jsp?id=332656
