Honda made a great bike in so many ways but I found the suspension was its worst quality. I had spent considerable time and money on fixing the problems and it totally transformed the bike. With the suspension changes it tracked perfectly through fast bumpy corners at high speed. The front end was much more stable and there was much reduced brake dive. Before making the changes I had considered getting a steering damper to control the front end wiggles but there was no need since the wheels seemed glued to the road. The new rear end easily absorbed both large and small bumps and there was no need to ride the footrests on rough stretches of road. The front and rear ends seem well balanced and another benefit was greatly increased comfort. It would be perfect for track use and gave an increased feeling of confidence.

I am changing to a Yamaha FJ-09 and I removed the upgraded components from the CBR. I would prefer to sell the suspension package complete but if nobody is interested I would split the parts. I have listed my price in Canadian dollars for all the items .
(shipping from Ontario Canada will be extra). If you have any questions please email me at [email protected]. I am certain that the components are in good condition but I will refund the cost for returned defects.

SHOWA REAR SHOCK from a Honda CBR600F4 with remote canister (Rebuilt Aug 2015). The shock was reconditioned re-valved and a new spring added by Jamie Daugherty of DRM Motorsports (DMr Performance Suspension). This is a top level shock with separate controls for compression damping, rebound damping and preload. The remote canister design means that it will fit the CBR500R equipped with ABS. The spring rate is the same (600lbs/inch) as the stock one on the CBR and is suitable for riders in the 150 to 180 lb weight range. The spring is easily changed for higher rider weights. I had two tries to get the configuration right and I had a longer canister hose added so I could get a perfect mount for the canister on the right side of the bike next to the rear brake fluid reservoir (see photo). A special bracket for canister attachment is included. Canadian $ 290.00

FORK SPRINGS & EMULATORS
A set of single rate FORK SPRINGS with a rate of 0.80 kg/mm plus spacers (Nov 2015). The spacers are sized for the regular fork caps. I am also including preload adjuster caps to fine tune the correct sag. Stiffer fork springs might be needed to accommodate a rider weight of more than 180lbs (springs are easily changed and cost about $80).
A pair of CARTRIDGE EMULATORS to completely alter the damping characteristics similar to a cartridge fork. The emulators are adjustable but were perfect as supplied. Adding emulators requires some modification of the fork damper tubes (Instructions supplied). For a full explanation of the role of emulators see this - Emulators-How They Work
Fork package (Springs & Emulators) Canadian $ 145.00

There's a YouTube video where a guy just put in thicker fork oil 20w or 30 w fork oil & added 20-40 more mm oil to make for a stiffer front suspension. For 2015 or early you could also add a adjustable front fork cap . Total cost just a little over $100.00. If you weren't going to do track days you could forget the adjustable fork caps, that's the major cost.

That's fine if there are no bumps. Emulators change the whole damping profile so high speed impacts are absorbed.

I am curious how did you determine which is the best front/rear shock as a replacement to stock ones? I have CBR '16 model, and admittedly don't know almost anything about mechanical parts, but I am also looking to replace stock suspension, and wondering which route to go.

What do you do (or want to do) with your bike? That will be needed for folks to advise you.

You can buy new shocks configured to your weight and riding style but they are expensive. The popular option is to use a secondhand reconditioned high quality shock. The front is a little more tricky because the stock orifice damping is very crude. Cartridge emulators are a big upgrade for relatively little money but some modifications to the fork damper rods are needed.

I obtained all my parts from Jamie Daugherty at (DMr Performance Suspension). If you have little mechanical experience you would need the help of a motorcycle mechanic for installation. Your weight is important for spring selection for both front and rear but springs are easily changed. I had to work with Jamie to get a setup that suited the CBR500 best and I sent the shock back once for a longer canister hose for easy mounting (see picture in my post).

To learn more about suspension check out the internet. One good site is Racetech. Here is their excellent explanation (with pictures) of fork damping - Emulators-How They Work.

Also, check my first post for a good price on a full package that works for the CBR500. Springs would be good if you are in the 140-180 lb range.

Do a GIS search for: “Shock Swap Myth by Peter Kates GMD Computrack.”

Ohlins offers their STX-46 shock absorber for the 2013-14 model CB-500F, but nothing for my 2017. Can anyone comment on this re interchangeability or whether there is a good replacement shock for the '17? I weigh only 135# and the OEM shock is pounding me to Jell-O. I did reduce the spring preload as much as possible. Still way too stiff and I'd really prefer a top shelf shock than meddle with the OEM unit. Thanks..

I weigh 140 lbs and have a 2014 C500F (non-ABS). The stock shock was not sophisticated but didn't pound me badly unless the pavement was really abrupt. Spring was well suited to my weight.

I did replace it with one from a 2017 GSXR600, much better. Paid about $40 on eBay. This shock only fits in non-ABS bikes, don't know about 2016-2018 model years.
Shock from GSXR before 2010 model year may raise the rear of our bike more than recent ones.

The first post in this thread describes replacing shock with a rebuilt, re-sprung shock from a Honda CBR600F4. Many people have done this. Very likely the person who does the rebuilds can say if it fits the '17.

I wonder if there is a problem with the stock shock on your bike? You could buy a take-off on eBay for a few dollars if you want to try another stock one.

If the rear of the bike was lowered, that affects spring and shock rates. Don't know how much.

Also try running lower rear tire pressures. Say 37 psi rear unless you carry a passenger and luggage all the time.

I have an Ohlin's on my 2015 CB500F, I would call Ohlin's USA and ask them about your 2017, I bet it fits. There are also other companies making good shocks out there, maybe find a suspension shop near you and ask them what's available. I use GMD Computrack Atlanta.
