Hi, i just bought a 91 bike with 18000 miles on the clock, the ride quality is great feels really planted. Have notice the preload has been fully adjusted to max, but if i really bounce down hard on the saddle it feels as if i can bottom it out. My question is the rear shock softly sprung? or is it time to replace, i dont want to buy and fit a new shock to find it the same because the handling feels sorted. Thanks Paul

 

early cbrs are softly sprung. For street it works really well. You only need extra stiffness at the higher speeds you get on a race track. How much do you weigh?

 

About 13st with gear on, Im gonna strip her down over this winter, main job is the fairings need some filling and a respray guess they are the 19 year old originals. Would be good time to swap out the shock, will probably check out how much sag i have when sat on it to see if its gone too soft.

 

F3 shock with the external reservoir is a direct replacement, or Racetech sells replacement springs for either shock.

 

Would a '93 900RR Cbr mono-shock work on a F2 in rear?

 

I don't beleive the 900rr rear shock does. I also don't beleive it's enough of an improvement to be worth it.

The rear shock will make a big difference, as will doing the front forks. A properly tuned suspension will help you be a far faster rider than any jet kit or exhaust setup.

Re-springing the suspension is a common fix. Getting an F3 rear shock and re-springing is also a common method. If you want to get REALLY aggressive, you can drop in an F4/F4i rear shock which will raise the rear 2.5". The bike will become a bit hyper, but man oh man is it quick edge to edge and puts down some serious power.

I've got a re-sprung F4i shock revalved and recharged by circuit 1 racing (now GP Suspension). It's a pretty damn solid shock if you want to buy it for cheap. I'm just sitting on it. It's a bit light for me (It's set for 185lb~ rider, I am 210) but it may treat you fine.

 

I also am 210 and wish there was a better repleacemnt than stock for the track. What about replacing the rear swingarm too, to get a better shock in the rear???

 

When you say "cheap", how cheap are we talking? I'm 5'9" and about a buck sixty, and I prefer stiffer springs, anyway. I'd definitely like to talk price, let me know.

 

Yes, but for the rest of us, we need answers to the rear shock. Updating the F2 and need a better rear shock on the track?!

 

I have one in the for sale section.
