Attention 06/07 YZ450 owners with cornering troubles.

I just sent my suspension to one of the guys Davej (Smart Performance Inc) who posts on Thumpertalk in the suspension section. I am glad to say my bike actually turns now. Who would have thought suspension makes such a huge difference with cornering on the YZ450.

Amazing.

I had the suspension on my '07 sprung for my weight, and set the sag up right, and holy cow this thing rails corners AWESOME.

Daves special oil, his piston mods and the IC springs are what makes this work so well. I have been testing these for a few weeks and yes it really does work. The Bike turns much better even with my 24mm Clamps and extended rear axle. I rode my 06 back to back with a stock 08 yesterday and all I can say is yes my 06 corners better, finally! And the instant power does not hurt either....I can not believe how much I like my 06 again.:eek:

Would you gentlemen please give a link to his website....if he has one.

Very interested in this. Also what are the costs?

Ga426-what clamps are you using? What axle extender?

I have had an 06 YZ450F since 3/06 and have not felt it had big problems once I got it sprung correctly for my weight. I have been off the bike due to long winters and serious injuries the past 1.5 years.

I am using Applied Racing 24mm top and bottom clamps Rubber Mounted

Axle extended to furthest point on swingarm - similar to Grant Langstons set up

I have been having problems getting my 02 426 to turn. I called Dave after reading a bunch of his posts and sent him my suspension. He got it on Sat 3 and had a message to me with a parts break down and suggestions by Sun 4. This is the best service I have received ever! Also he did not try and talk me into a WORKS set up, but instead kept it reasonable. My forks had been butchered by the guy who owned the bike previously. Dave almost laughed when he told me " You must be hard cause that had to be one of the roughest rides out there!" It was too! 600 bucks for a lot of broken parts, rebuild, cleaning valving, re sprung, and shipping! I will have them in two days, today being the 5th. Less then a week for a full suspension set up! amazing!

Gray, I also switched to 215.VM2.K5 a week ago and came away with pretty much the same conclusions as you. It was almost uncanny how similar our observations were: http://www.thumpertalk.com/forum/showthread.php?p=6342042#post6342042

Pretty amazing stuff, i'nit? :eek:

GreyRacer and Wiz - I am curious what oil height levels you experimented with and results....please tell.

As I mentioned at the end of my review, I used 11 ounces of SP5 in the outers. That comes out to 325cc. The inners are, of course, filled.

I have 12 oz (354cc) in the outer chambers at the moment which has resulted in me runnng my comp. clickers way out, i.e., 14 - 20 clicks. The interesting thing about this is that while I could feel that I needed to drop the amount of oil it was never harsh and was (is) actually rather plush. So far all my riding has been on tight singletrack woods trails.

I will remove 25 - 30 cc's before my next ride which unfortunately will not be this weekend. My GF & I are celebrating our birthdays in Las Vegas this weekend :eek:

I finished the day at 12C and 14R, but I'll probably be fooling with them some more.

Nice....that's a good one. :eek:

how much does the stuff cost? the oil alone. and the mod. I've read a bit about this oil and it sounds amazing. is it cheaper than regular re-valve work done by the big suspension companies? sounds like it performs better lol.

At this point, I don't think the fluid is available for general sale, as it's still in development.

But to get the straight scoop, contact Dave at http://www.smartperformanceinc.com/
