Need help sorting my forks

I'm ready to upgrade my SP1 forks. What do you guys think I should use?

I was thinking about RaceTech gold valves and springs. Looks like about $360 might get that. I want to do the work myself, especially after seeing b.miller123's thread about it. I have a manual and I've already changed my fork oil. Hoping it's not going to be too difficult.

I'm hoping for some suggestions of what internals to use.
I'm about 185-190 with all my gear.

fwiw, I've just installed an Ohlins shock out back. It feels good, I guess. It's hard to tell with my forks being so under matched.

I and many many others have raced using racetech valves and springs. They are great quality. Go for all (springs, comp, rebound). Google for used options too if you want to save money, including parts and whole forks. I found full racetech rc51 forks currently for sale in 30 seconds.

call racetech for spring rates.

Thanks Kwtoxman. I remember you saying you were racing your RC51 when they first came out. I'm probably going to go with building them myself, rather than buy someone elses. Cost is a big consideration for me, and I like the idea of putting my own custom parts in the forks.

Actually, costs are cheaper buying done forks and selling your stock ones.

Technically, I tracked the rc51; I raced an f4i.. Good memory still though.

There are several things in life where you do get what you pay for. At the top of that list in no particular order would be:

Motorcycle suspension
Women
Divorce Attorneys


There is a reason you don't see racetech parts on championship winning race teams at the top tier levels of racing. There is a reason why Honda who owns SHOWA suspension is using Ohlins suspension on their Factory Repsol team and there is a reason why World Superbike Champions are all using Ohlins instead of any other brand even though they can afford to buy any brand of suspension they damn well please...

Jon,
I don't know Ractech, but if their fork internals can be matched with your shock & spring, then it may be an improvement.

As for LDH, I never paid for my women (fancy dinners, exotic holidays, European wedding & family costs aside! ) and hope to never require the services of a Divorce attorney.

Pretty happy with suspension from other brands too on bikes & cars, but then I'm not a world class racer, nor I daresay is Jondog9.

Euro RC51 SP2: HRC WSB Ti Hi-Level, T1 Airbox & Snorkel, PCIII, Dymag CA5 Carbon Wheels, Ti64 Spindles (F, R & Swing Arm), Mori Link, Maxton GP7 Shock & Ohlins 832 Forks, Brembo GP Calipers & SBK narrow track (F), Braketech Disc (R), Brembo billet Underslung x 2 Brembo RCS, Tyga Triple, 7075 Stem, Probolt Titanium all over, Babyface rearsets, MR Complete Carbon Lineup, Custom Undertail & CBR 1000 LED, Watsen LED Indicators, Harris Brace, Giles clip-ons, Corbin seat, etc. 2013 BOTY.

You can use, Race Tech, Traxxion Dynamics, Ohlins/Kyle valving with your OEM cartridges.
Or you can replace your OEM cartridges with Race Tech or Traxxion Dynamics, Penske cartridges (with TD or Penske, you have a choice of conventional or gas pressurized units).

Forks are pretty simple in design, and aren't too difficult to disassemble, with the right tools.
Some special tools are useful or needed for complete disassembly, depending on manufacturer.
