Cool ohlins vs. OEM

How much better could it be?Ive got a gix 600 filled with race tech and Penske and my stock 01 gix750 feels just as good if not better.I m just wondering if I am missing out on something better.

You gotta have the right set up and geometry. and it makes a huge difference! Plus you'll save the money you spend on a shock just in tires!
I just set up a 2002 750 for a buddy w/ an ohlins and thermosman forks...the bike was on a rail! I set it up similer to Robert Jensen's bike 750.
He couldn't believe the difference!

But all and all you have to have the right set up without that it really doesn't matter what parts you put on. You could put on the same dunlops that rodger hayden runs but without the correct geometry and set up it's gonna be a waste! YOu'll think your 208ZR work better....ya know??

Yes, you could have bought a Honda.

I rode a 954 at Jennings,loved it On the 750 I did the usual stuff with sag,ride height.Took comp,rebound to extremes.Due to the lack of track time I couldnt decide if it was me or the bike.

Oh, you know I was just teasing. The 750 Rocks on the track! I thought the 750 Gizzer's stock rear shock was supposed to be pretty good. You may not see a lot of difference unless you are really pushing and heating it up. If I read your original post right the 750's suspension is bone stock? If so, I'd do the rear last. Springs and valves on the front will give you the biggest bang for the buck. Oh, I have RT 100 springs and gold valves up front too. I wish I would have gone with Hyperpro progressive springs with the RT gold valves unless the 750 is 100% track and even then I'd consider the Hyperpro springs. They make a really good rear shock too. It's also less $ than Ohlins.

I'm sure the hyperpro spring will be to soft!
I think the raising rate spring (ex hyperpro) is a great concept but it's hard to dialed in...
Btw, hyperpro springs seem to work ok for street bikes....I just haven't had much luck with them on track.
But susp it's hard to do it in steps...a lot of times (depending on how hard or fast you ride) you'll go thru rear tires with the stock setup. A rear shock will help that...well it'll allow you to adjust out any issues.
Up front...you gotta have someone who knows what they are doing to do the valve and the spring...if that's messed up the bike will do all kinds of weird stuff...
But again like i said...you have to get your geometry and base line stuff in the ballpark...
I guess you can get a totally stock bike to work okay if you get the geometry right.

almost all stocks are JUNK! In fact I don't really know of one that works good for the track.

Rob, why would you adjust the rebound and the comp all the way in??...that's part of the reason it handles like shit.

Btw the only reason I like the ohlins is cuz of the preload adjuster...I had Thermosman revalve my ohlins...
But ohlins or penske whatever one you want they both work good.

Didnt take rebound and compression all the way.But sometimes when I try things I go a few clicks more in one direction or another to show what direction the changes are going.If I have time I set it back to baseline then run it again.I keep good notes,something I learned in my stock car days.One or two clicks or a mil of rideheight is too small of a change for me to feel.But if my girlfriend was a cup size bigger I would notice that .Things I noted at Gingerman,T2,T3 it was real herd to get the bike rotated in another direction at the apex.Between 7/8 same thing.Had to ride around that dip in T11.If I hit the diptook longer to find the gas (thats also where you passed me Dano )

Pick up a copy of "Suspension of Mortals" by Traxxion Dynamics. Dude, you'll learn alot. Cranking on rebound and compession will only reduce traction because the suspenion is NOT doing what its suppose to. You might as well be riding a rigid!!

I'd have to see where stuff is set on your bike. (example how much fork is showing and your shock length)
But it sounds like you may have to add low speed compression to the rear...
Next time we're both at the track Rob stop by my pits I'll help you out!!

I have the book.I dont have it set rigid. I know what thats like.Not so good.I was trying to say was.I cant notice small changes so i exagerate them to see what directoin theygo.Hard to explane .Forks have 6mm showing and the shock have 11mm shimsunder that. 200 pound with gear. I have to check notes on sag.Forks did not bottom I will probably take the Penske off the six and put it on the 750.

Has the fork oil been changed? Oil fork oil is like water and any adjustments you do go un-noticed. I changed my fork oil after Barber and now the adjustments I make I can feel to a degree.

Have you ever rode a bike setup correctly with Ohlins? Your 01 Gix 750 has good suspension, but it's not even close to an Ohlins set up. If you put Ohlins suspension on your 01 750, and had it set up right, it would transform the bike more than you can imagine. I had an 01 Mille that was set up pretty good. It had good stock Showa forks and an OK Sachs shock, but it worked for me. Now I have the Factory with all the Ohlins stuff, and it is a night and day difference, and it's at stock settings! I could easily feel the difference and I'm a novice.

Ohlins suspension is probably the best suspension you can buy. However, you can buy Ohlins internals for almost any fork that would make them close to an Ohlins fork, for a lot less money. I also have heard a lot of good things about certain Penske shocks. Some of the higher end ones are just as good as an Ohlins, and one of them even offers more adjustability than an Ohlins.

Like Dano said, it really doesn't matter what type of suspension you use, if it isn't set up properly. Suspension set up is all rider feel. That's why there is so much adjustability on the componenets. Everybody rides and likes something different.

Yes, that was Jeff's Tesi. You know him to, then you've seen his yellow Ultima?

The front oil may be broken down. It's just like car oil it needs to be changed. It's just a thought.

My GSXR 750 has an Ohlins rear shock on it, but I brought the bike that way. I just know it has more adjustments then I care to know.

Ive seen and passed allot of bikes with shredded tires with Ohlins then every once in a while someone tells me what I have could be better.I think Im off topic a little. I had an ohlins guy (Rep) play with my 600.It was a little better.
