As befits its racing intent, the RR is endowed with a few extras such as lightweight forged (rather than cast) pistons, a back-torque-limiting clutch, adjustable swingarm pivot and a threaded frame boss to accept a steering damper. Also, like the base R-model, the RR’s rear ride height is adjustable via 1mm shims. None of this chassis trickery mattered to us at California Speedway, however, as the required shims and pivot plates were apparently still on a boat bound for Long Beach. Truth be told, Kawasaki wasn’t overly happy to provide us with an RR. The bikes will be imported in limited numbers, the main focus being the 636, and the one test unit available was a little tired, hence the mandate not to street ride it, dragstrip it or get it anywhere near a dyno, never mind those stipulations doomed the bike to sidebar fodder. (Towards the end of our test, a new RR was broken loose, too late for inclusion, but at least we got horsepower figures).
