I fitted the Matris fork kit last week on my Breva 1100 and it is a much sweeter ride. The bike just feels more planted and responsive in turns and I feel more competent as a rider. I ordered the Penske 8900e rear shock and when fitted I will report the results. I ordered the Penske on the strength of my Stelvio having one when I purchased the bike and love the way the bike handles and rides. I do not believe I would hesitate to purchase the Matris rear shock now after the results I have experienced with the fork kit.
Oh yes, the fork kit was very easy to fit, just plug and play, the hardest thing was fitting the front axle. I also used 15w fork oil.
