I have just ridden my newly freshened up SP4 for the first time, well ridden it back from ItalSport in Bury to home.
The bike is phenominal, power everywhere!, KAIS have sorted the suspension, they have changed the rear spring to a 100kg, from 110, rebuilt the forks with lighter oil but decided to keep the standard springs, the suspension feels superb. I am well impressed with it, just got to get it MOT'd tomorrow and Taxed then I will be all Legal.
I have fitted HH EBC pads, bled the brakes through with fresh fluid, fitted a pressure switch to oprerate the brake light, so it now stops as well as it goes.
I can not put into words how much better the bike is from when I first test drove it in the back end of last year. It has been expensive but well worth it.
Will post photos when it is cleaned up.
