::I have swapped it for a more specific (and less obstrusive) maintenance template. Two of the reviews remarked on the lack of compatibility with various Nikon cameras because the camera body interferes with the shifting mechanism. I don't think we currently mention that; we probably should.  
 ::Regarding your sandbox draft: That still needs some work, I believe. It seems written for a specialist, not for a general audience. For example, the very first paragraph talks about the R68's "more modern looking front fender" - more modern compared to what? (Also, the second paragraph's fender description is much better in that it describes the changes instead of just calling them "more modern", which is rather vague.)  
 ::I'm also skeptical of the rather long quotes. We should probably rewrite that in our own words, especially as the two quotes are partly redundant. 
 ::The draft also says it's "the most desirable postwar BMW motorcycle". That's a rather subjective statement and would require attribution to a secondary source ("Historian/reviewer/whatever Smith called it the most desirable postwar BMW motorcycle"); otherwise it's editorializing, which we should not engage in. (On your user page you call it the "rarest and most valuable", which should be much easier to find sources for.) 
 ::I'm no expert on motorcycles, and the people at WikiProject Motorcycling may give you more specific advice.
