Speedmaster Harsh Ride-tyre Pressure?

What kind of adjustment do you have?
Pre-load?
Compression?
Rebound?
Or which combination?

 

Pressures sound ok
Did to tell Hagon the usage and weights as they are usually pretty good.
Go back to stock and send the Hagons back

Talk to Hagon. They will adjust or modify for you. I took a set of my Harley and they resprung and adjusted them to fit the 1200 Bonnie I had. That's the problem of buying second hand. You only have the sellers word as to how they were used or weights and style of riding.

Did you get instructions? What is the default settings? What are they set at the moment?

 

Bloody hell 36 and 42psi ....no wonder its harsh....not saying its not supposed to be that pressure but it may be worth trying reducing the rear by
a few lbs, its not the same i know but i only run 15psi in my Avon SM...mind you its the only rear suspension i have with a hard tail.

 

I would set the shocks and forks to standard then work from there. You might want to try the tires first.

 

Are they too soft and bottoming out ? I found this with mine with the settings on minimum they were bottoming out causing a really poor ride I have since set the preload to 2 and compression/rebound damping to 6 and the ride is much better

 

It doesnt matter what setting you have if the the spring is built to take someone heavier The preload only raises the back end to keep the sag correct whilst riding and rebound determines how fast the shock recovers from being compressed. I bought an Ohlins but i found that the spring was too soft for fast riding around bends but great for absorbing bumps so went to a spring that gave more stability but was a bit harsh on bumpy roads. Plus a spring that may be great for two up riding may be hard when solo..

 

But fast solo and steady two up maybe similar settings.
Start off with determining what the spring is and seek their advice. An incorrect, for your use, spring rate will never be good despite what the damper settings are.
