bradders if you looking to fit radial calipers, Monster S4R Testastretta (2007-2008) Showa forks are 50mm top 54mm bottom
as the S4RT is a heaver bike the stock spring rate might be a better fit for you then those spongey 620 marzochis
you might need to find some 15mm offset 6 hole rotors though
dont know if any of thats legal for DD mind
