g00ner I fitted Hyperpro springs bought from a member from here, changed the fork oil as per their spec, the bike rode better with the crashing over bumps almost gone and the front end quite a bit smoother as you would expect from progressive springs
I only bought the Ohlins front springs as they come from a guy I was buying a couple of other bits from and they had Ohlins stamped on the top of them and a sheet of Ohlins stickers with them LOL
they also used the same weight oil so I did not have to do the oil change again
To be totally honest I cant tell the difference between the Hyperpro and the Ohlins springs they seem to ride the same but either is without better than the standard
with respect to changing them which can also be dont using the original fork oil ive been told is a really easy job took about 20 mins in total all I used was a trolly jack to lift the front wheel just off the floor to release the fork pressure a bit tools needed 17mm spanner or socket and a coat hanger bent at the end to hook the springs out, once the cap is off pull the spacer then the washer then the spring out, trying not to loose any oil then simply reverse the process with the new spring
job done
worth doing Yes id say so im hoping the new rear shock will make the bigger difference tomorrowbut I will let you all know
