Matris makes a set of drop in cartridges for the Standard Street triple that includes roller bearing pre-load adjusters on both legs and compression adjustment in one leg, with rebound adjustment in the other. Both on top so they drop right in the stock fork tubes. They will also customize the spring and valving rates to your needs. Comes complete, ready to install including fork oil.

They are not cheap but I have the high end Matris FO-5R cartridges for the R in my bike and find them to be better than the Ohlins, Traxxion, and modified OEM forks I have had on other bikes. PJ & Paige at PJsParts.com are US dealers for Matris and can help you with pricing. E-mail them and they will contact the factory directly for the best up to date pricing. A plus is that Paige also rides a Street Triple.
