2010 yz450 suspension?Anyone worked on it?

[aedwards07]

Does anyone have any experience with this bike yet?Im looking to get it revalved and resprung.I just wanted to know who has worked on it so far as I dont want to send it to someone who hasn't even touched one yet let alone tested any settings.Im a fairly aggressive B level mx racer at 6'2 and 210lbs so im looking for something fairly stiff.

[aedwards07]

Really not too big of fan of the whole Racetech setup on anything in paticular.Looking for more of just a standard revalve.Thanks for the info though.Any recommendations on the correct spring rate?

[rider211]

you need 0.48 fork and 5.6 shock, and if i was you id send it to enzo racing they specialize in yamaha's kyb stuff,some of the best suspension work you can get, rg3 also does realy good with them to and you can bet there already on top of it since they both do alot of pro bikes enzo especially with yamis, i had them do my 08 and 09 kawi 450 kyb's and man there do make miracle's happen

I would leave it alone,Just spring for your weight and you will love it. Not exactly the same but I have an 08 yz250f and just set up for my weight and suspension is awesome. Yamaha has the best stock suspension. i did not know the 2010 was on the east coast. How do you ike it.

[aedwards07]

So I made an attempt to order springs today and realized I cannot find anyplace that lists springs for the new yamaha.Do the older springs fit fine or does something else cross-refrence over?

Dunno too much about KYB but my bet is the -09 fork springs, at least, will fit. Call Enzo and ask them. They must know.

[rider211]

im not so sure that the 09s will fit, they have more travel this yr. 12.2in last yr was 11.8in so the springs must be longer this yr. rite?and the shock was 12.3 last yr. now its 12.4, but like i said and so did villektm enzo will know 4 sure give'm a call..[714-541-5218] nobody know more about kyb then them the owner was a kyb industry company test rider,engineer,and tech for a long time, 25 yrs. or more i think

are not the std springs around 0.48 and 5.6? have you checked the sag with the std springs?

The yzf in 2010 has plenty of damping as std, have you rode it yet?

[skynard42]

Fork springs are the same as the '09 kxf450.....shock spring is the same as used on the '09 crf450 and the '09 kxf450

there .46 57

[rider211]

there .46 57

oppps hit the wrong # .46/5.5

[mog]

i would just preload the std fork springs a little.

oppps hit the wrong # .46/5.5

Are you sure about those spring rates. KYB says there are 4.6N in fork and 56N in rear (-09 54N). I am not sure about US models...

ross maeda is THE man, he owns and runs enzo, he is the ONLY guy i have ever let touch my kyb suspenders. he goes to japan every year and helps to develop the factory settings. nobody knows kyb better or sooner than ross.!!!!!!!!!!!!

These are for Japanese market, so you might have stiffer stock springs for you Americans. Not sure why there are two different parts numbers for Rear spring in same weight though....

[aedwards07]

Probably because there is a blue spring and a red rear spring.I didnt even think to try to order OEM ones.Time to check on a price.

[mog]

just be sitting down when you do...

[aedwards07]

Well I got fork springs for $62.It was around a $1 or 2 over dealer cost.Retail was like 110 or something.The shock spring was $110 and retail was like $200ish.With the discount it wasnt bad at all.
