Currently available shock absorbers?
Mikep328:
Hi All!
Took the 400F out yesterday after a 5 month layup - started/ran perfectly! :) BUT (there always seems to be a "but...") I now find the rear shocks to be less than I'd like. I replaced the old shocks last year with a pair from DSS which fit perfectly and look original however I'd like a pair with improved capability - some adjustment other than the spring tension would be nice.
Any thoughts for something better than the DSS?

Its the "currently available" that trips up my thoughts on this. Not practical to suggest, but there appears to be some "Ikon" ex Koni design floating around that would be good if available in correct fitment. Ordinarily they were a well designed and made item when sold.
Something else to consider that makes a difference if significantly out of range is tyre pressure, that's if you've not already considered it.
There's usually a load index statement on the tyre to facilitate calculation of running pressure correct for the vehicle its used on. Modern tyre construction and resilience being someway distanced from original contemporary fitment, and can be bone hard if used on mild applications like this.
If you've got those details we can work out a more defined starting pressure to suit the bike which can make quite a shift in ride quality and grip characteristic as well.

Thanks for the response. I fitted new OEM-size Dunlop K82s last year 300/18F, 350/18R and set the pressure per the owners manual for rider only - 26PSI F, 28PSI R.
Load rating is 47F, 56R
K2-K6:
There should ordinarily be also a load rating on the tyre stating something like " xxxx kg @ xx psi" to be able to calculate more accurately and check the specification.
56 R will give 106mph maximum speed, but will be capable of constant running with a 224 KG payload ..... for just that one tyre !
To calculate competently, the load in kg / at xx psi is the detail needed to extrapolate a valid start point. This may differ from original Honda spec as current tyres are often significantly more capable in load carrying than the original fit, potentially making them too rigid if not checked like this.
It can just make a vehicle seem very harsh in suspension as they don't yeald in normal load situation as the original chassis engineers would have designed for.
Its an interesting practical exercise anyway and can be quite revealing in vehicle dynamics.

I seem to remember YSS shocks being recommended by a few members on here.
