That’s a good description of the winter roads in the UK

My personal view of the CT suspension is that it’s fine on fast sweeping bends but can be a little harsh and skippy when pushing on down our country lanes.
Manufactures settings are a compromise and need to be adjusted not only to work with the rider’s weight and style of riding but also the type of terrain the bike is being ridden over. A bike set up for mainly off roading won’t work so well on a fast Main road.
A few years back I had a set of uprated fork springs and an Ohlin’s shock fitted to my Pan and then had it set up by a professional. It was like having a new bike. I take it back every 16000 miles to have both ends serviced, that keeps it working like it was when first fitted.   
For now the CT is fine for my style of riding but as the springs settle and the oil degrade’s I will be looking for an alternative set up.

Hi Revenue,

I have also the problem with suspension. I am not frequently using my bike on gravel but the tarmac roads in my country have a lot of faults,cracks or holes. I am always complaining about the harsh character of the front suspension. Did you recovered this with Hyperpro ?
I also know that the rider weight is also important. I am 80 kg. What about yours ? This will effect directly the SAG value.

Well i am 100kg  :034:
The SAG with me on the bike is 46mm or +6mm on the bike only SAG
Which is better than the 68mm SAG before!! or 22mm more travel at the front end :028:

Hi mates,

Take into account that Sag is not a single measure, it's the difference between two measures and it does not depend directly on the weight of the rider...

In other words, Sag must be kept between certain measures independently from the weight of the rider or passenger or luggage...and besides, there are different types of Sag, Free Sag (also called Static Sag) and Ride Height (also called Total Sag or Loaded Sag)...and besides, correct spring preload to obtain right Sag is really important...if you cannot obtain the correct Sag recommended by the manufacturer, depending on the use and type of the bike, then you must change the spring itself...

If spring preload to obtain right Sag is not possible then the bike will never work properly independently of adjusting the extension or rebound nuts...or compression in its case.

If you read specifications given by hyperpro for CT forks, you can read they recommend a Static Sag of 40 mm...that leads to a recomended Total Sag between 45 and 50 mm...

In an adventure bike like ours, or a crossover according to Honda, it is accepted that Total Sag or Ride Height should be about 1/3rd of total travel of suspension system...in our case, and according to Honda specs, 145 mm is total travel of our forks...so, 48 mm of total sag should be a good starting point to get our forks done...
