Here are a few lessons learned from recently adding a set of Renthal aluminum handlebars (stock profile), Cycra Pro-Bend handguards (with the triple clamp side mount system) and Zeta four-finger levers on my 2005 DRZ 400SM. First lesson learned; because of the added thickness of the triple clamp side mounts and in order to get the proper thread engagement on the triple clamps you will need four 70 mm long, 8x1.25 bolts. This additional length will allow you to use a flat washer and lock washer on the bolt, which I did. Second lesson learned; the easiest way to mount the handguards is to extend the 8 mm slot in the pro-bend bar approximately 1/2” to the outboard side of the bar so you can slide the bar flush against the end of the handlebar. With the stock-length slot in the pro-bend bar and the two holes in the side mounts there was no way to get it all to line up well and sit flush against the end of the handlebar. Luckily I have a friend with a machine shop, so this was exceedingly easy for me… Third lesson learned; while I like the Zetas, the length of the four-finger levers force you to move the perches inboard on the handle bars to get adequate clearance between the end of the levers and the pro-bend bars. If I had it to do over again, I’d get the three finger Zetas.
