Bought the right hand (brake) guard first. Mounted it using Woodcraft's hand guard mount bar end. Fits perfect, highly adjustable, and out of the way. The bar ends only come in two, so I have a spare. Don't forget to tighten the bolts holding the plastic to the aluminum stem. I didn't and lost the plastic guard along with the bolts the first time on the track. Luckily it fell off somewhere in the paddock and was found before the next session!! Bolted it back on with some spare bolts.
Would like to see spare bolts and the spare plastic guard piece available separately. Also would like to buy just one hand guard mount bar end.
