You could try a more economical way first before shelling the money out for a lock-up and side case mod. You could try some street bike fibers with the banshee steels and heavy duty springs. Alot people I know run either the FZR1000, R6 or 650 Maxima fibers. I run the Maxima fibers in mine with the stock steels and Barnett springs. I have been running it for a year now with 80HP and 45 ft lbs of torque. I also think Hinson makes an 8 plate clutch basket setup that will fit in the stock side case. The lock-up is probably the best way to go, just a little expensive. And yes it can be used for trail riding. Hope this helps you out.
