Murray Mint, There are two main types of protectors for the Dukes..... One that mounts on brackets that are basically 'clamps'. These grip around your trellis frame. I wouldn't recommend them cos it's obvious what's gonna happen in an off. Mine are the stronger type by Cyclecat. You replace the engine mount bolt that goes straight through the battery box (on the 748/9** models) with a new item that has collars on either end. The 'bungs' then screw onto these collars. In an off, they aint going anywhere. If they do, the frame would be the last of my concerns. The engine block is the main stress member. They do work...I tested them at Croft 2 weeks ago. No engine, battery, clutch, or tank damage and very minimal fairing damage. I only 'plan' to do lowsides. I don't crack the throttle wide open, so highsides will be rare. Of course if you highside and launch the bike 3-4 feet in the air then again, I think the bungs will be the last of your worries. Dodging the asteroid-like debris would come first....... Guido |
