Thank you to all,
I looked on progressive website - interesting stuff - they have a 25mm lower rear spring which presumably drops the back end down 15mm or so. 95 euros is affordable too (for the rear shock). Actually, although I have owned 15 motorbikes or so, I am least comfortable on this one partly because how high it is (I've dropped the front 7mm) so the idea of my bike sitting a little lower is very appealing..
when you say you put a progressive spring in - I'm guessing you are talking about the front..? Racetech states the stock is 0.70kg/mm, and that I should go with 0.93 = I have to choose between 0.90, and 0.95
I'm thinking of 0.90 because 95% of the time I am riding solo without luggage...
Thank you all
