I used to race in "ss400" class with an MC21 in the Greek Championship and I was using the Ohlins rear shock...Way better from everything else... The possibilities of the shock tremendous... I spent many, many hours to set up the bike correctly...I remember that I used to have the less power from all the competitors (it supposed that my class was a stock class but everyone were cheating) but I managed to finished 2nd in 1998... My opinion... I prefer to have the best set up in my suspensions and brakes than having power that I am not capable to manage...
I think Ohlins is the best choise but not the only one for a good set up...
