Yeah this has to be the best bang for your buck mod...for our harsh stock shock ..
I went to E Bay and bought a Yamaha 2008 R1 rear shock for bucks..
Took it down to the local machinist to drill out the eyelets to 12 mm... bucks..
Bingo..set the preload to max and if your like me ...solo rider and 160 lbs. the R1 spring will be a little soft..
However , I get a 50 mm rider sag and the compression and rebound is fun to play with...
This is my second R1 shock transplant and the results are brilliant..
Plush , compliant , and you can source a better spring cheap too..
Thanks to this wonderful forum and the great sharing of info..you guys rock !:wink2:
