07 yz450 suspension

I'm over due for suspension work. I weigh about 200 lbs, should I mess with revalving or stiffer springs? or stick with stock and tweak a little stiffer....

I am still a beginner rider (2years) but am pushing the bike a little harder than when I first bought it. I am not excited about the prospect of spending $500 if I'm not good enough to even notice...lol. Of course i used to think that I wouldn't notice the difference of a different tread pattern on the front....lol I was way wrong...

Even a beginner to novice rider will benefit from suspension work. At 200lbs yes you absolutely must have springs .48front/5.6rear and the correct ride height/sag is critical....to help build confidence jumping, landing and progressing.....:p

In order to custom revalve for you abd your ability, You must be able to determine what you like do not like....ie...landings, how it corners, braking bumps etc....then articulate what you do not like...too stiff, not enough plushness...bottoms too easy, can turn, too springy on lift offs etc....in order for a custom revalve. If you can not do this yet it is ok. Just tell a good to great reputable suspension tuner to revalve it for your weight and ability and they should have enough experience to set the valving spec for your needs. Keep in mind this is not a exact science and tuning the valve stack may be in order until you find the perfect nirvana. Make sure your suspension guy will work with you on this.

This will in itself help make you a better faster rider because your confidence will increase with these changes....so in my opinion the 500.00 beans is well worth it :thumbsup:

The '07 came with .48 fronts and a 5.5 rear. Like I said, Race Tech says you should have a .47 front and a 5.6 rear. Since they don't make the .47, they would have you keep the stock .48. The 5.6 rear is barely stiffer than stock (7 pounds/inch effective rate at the wheel). Worth bothering with? MX-Tech says no.

But, you can check it yourself:

That will tell you about your rear spring rate.

total Control suspension, 336-578-1906, ask for Chad Newton.

tell him Kyle Pulley sent you.

Thanks. It was early. Not enough caffeine. It's fixed now.

Is that 200lbs with or without riding gear? Get on the scales with all you gear on. And let the people who are tuning your bike know as much detail about your riding style. Be honest with them. It's really nice when you can fined a shop that actually goes to the tracks you do. It helps if they can see you ride.

You will need both springs and re-valving to dial it in. The good thing is that it is worth it! And you'll wonder why you took so long to get it done once you ride again.
