800 Brutlale Suspension

I was never really happy with the suspension on my Brutale, its an 800 RR 2016. I would hit some road bumps and it seemed to want to catapult me off the seat. Not a very confidence inspiring feeling. There is a suspension specialist near me, Computrack. I called, he told me to bring it in and see what he could do with the stock components.
He basically thought the suspension ratio was way off for that bike. He could do some custom work but for now I wanted him to adjust what I had.
The front is way too soft and the rear is very tight........ He actually added some preload to the rear shock, and explained it all to me, but .......... I am not very knowledgeable with this stuff. He suggested that I change out the rear spring as next step. He also stiffened up the front. I rode it on the super slab and on a local twisty and it is much improved. I may have the spring changed but for now I'm much happier.
Fairbanks and Fairbanks like this.

Thanks George, I will read this.

Fully geared I am about 160 lbs.

I basically understand why he added preload to the rear, he wanted to keep the the spring within a certain range for most situations.
The spring is progressive and so when it compresses beyond a certain point it gets really stiff and then release its energy and I go up off the seat. By keeping it loaded it will limit the progressive range of the spring with my body weight and only if I hit a substantially large bump with I be catapulted off the seat.
This is an overall improvement and while it's not perfect it was cost effective and works for the greater percentage of my riding ventures.

I have a bit of a clarification;
After I spoke to Peter, the owner or Computrack, Boston.
Where I stated " suspension ratio" that is an incorrect term it should be "Leverage Ratio Curve". Peter can correct this by fabricating a new link.

This is a quote from him "I think the problem is the Leverage Ratio Curve being too progressive. If we get enough response I can look into making a link."

I had my dragster shock revalved and they also replaced the spring with the one pictured - massive difference. Also replaced the fork cartridges. I'm about 160lbs in gear.
Bike is brilliant now.

Fork springs for Rivale needed!

This bit of info was a find after searching, and searching... for new springs for my Rivale. Am mid-way through a 2-day trackday (and having awesome fun!!) but the harder-than-normal riding has uncovered a pretty unsatisfactory setup. The front springs are way too soft, and were rectified by a suspension service guy at the track. However, the preload is now maxed and the guy firmly recommended getting a pair of new springs. This company Andreani might be the ticket, but I can only find a complete cartridge kit with springs. Did you get a choice of springs?

Im asking since I couldn't find any detailed info here: Benvenuti nel sito ufficiale di Andreani Group International

Also, any alternatives or additional info would be most welcome

I had the fork springs specced to my weight, and they came separate to the new cartridges.

Thanks Nickelmouse. Have you had any experience with those cartridges on the track?
