Try I: stock XR650L Rock Guard (requires two 2" spacers & 9 1/2" X 3/8" bolt - and a bracket to hang from the Oil Cooler bottom bolt).
TryII is a stock plastic XR650R Skid Guard attached to a Givi Engine guard (Installed over the XR650L guard). I had to make a bracket to wrap around the 1" diameter Givi tubing. Since I do not plan on taking this on serious trail rides - Plastic is O.K. The plastic XR650R Skid Guard does require a small metal spacer to keep the hot exhaust from melting it!
Part# for XR650R Plastic Guard: 50351-MBN-670ZC (H/C 6374151)
Should be less than $50 via a Honda Dealer.
Most serious XR dirt riders upgrade stock guards to Heavy duty Skid Plates. Should be several stock XR guards for available.
Yes - both guards are attached - but the plastic XR650R guard is attached independently of the XR650L metal guard. The XRL metal guard gives better protection from rocks & the Plastic XRR Guard protects from debris & road grime. If you have an engine guard like a Givi or Motech - then you can attach a XR650R plastic guard by itself (making a couple hanger brackets). Of course, the ultimate Aluminum Skid Guard is the SW Motech.
