Mark, I need to re-spring and re-valve some SBK forks I put on my 1997 900 SS/SP. I was thinking of trying Racetech (20% discount coupon from Fastrackriders school) but wondered if you could explain the Penske valving. I have a Penske shock, but was unaware they do fork valving too. Would you recommend that over Racetech Gold Valves? Who do you send the forks too?
Thanks, Joe

Re: Buckelew...Penske valving? (Joe B)

I believe tha Penske is starting to use some of the internals for the Showa's that GP suspension developed, you might find a bit more info on their site http://www.gpsuspension.com. I know they have been coloborating a bit lately.

Re: Buckelew...Penske valving? (Joe B)

Joe,

Suspension is a technology all on its' own. I understand big picture, but leave the details to people who specialize in that kind of stuff.

I think the main improvement comes from flowing more oil. To that point, I don't think there's much of a difference between the Race-tech, Penske, Ohlins, K-Tech, Traxxion Dynamics or any of the others. Tunability is where I think the differences are. Someone who knows about this stuff could address the topic far better than I.

The guy who did the work on my suspension works with Penske and Ohlins. He chose to put the Penske valves into it because of his relationship with the engineers at Penske. If he's got a question, he can talk directly with them.

All I know is that flowing more oil is good. The results are outstanding. I don't have the experience to say that one is better than the other. I can say that the valves are better than no valves.

Hey Joe, If you are interested in the Penske front fork conversion, let me know. Rick(at)cogent-dynamics (dot) com.

The Penske conversion replaces both the compression valve (foot Valve) and the rebound valve along with its slip ring seal. The compression side uses a cool 2 stage valving set up.
