“… today’s twins (1983), even those made by the old guard companies, really aren’t that simple any more. Black box electronic ignitions, replaceable but unfixable, are the rule. Double overhead cams, shims, buckets, three and four valve heads and all manner of counter-balancers are all part of many a modern “simple” motorcycle. And if the simple – so-called – motorcycle is really complicated, yet doesn’t deliver the performance of the more complex motorcycles, why buy it?”“Simplicity is a virtue of necessity”, said one engineer. “When you don’t know how to make a complicated engine that will stay in one piece, you make a simple engine. When you can’t get materials of high enough quality to last in a complicated engine, you make a simple one.
Simplicity is the goal of good design. Doesn't mean it's easy.Piston engine not simple. Turbine simple.
What sort of turbine? Certainly not the piston engine's counterpart, Gas Turbines are complex and expensive, although I agree the concept is simple the execution is not.Compressors are very complex pieces of flow dynamics and turbines extremely complex in their material science and there is a lot lot more.Well in my world they were but that could be because of my simplicity I guess
A friend (now 90 something!) used to drive Constellations. He says it was pretty common to start out with 4 and end up with 3.. ;D Or even 2. :oI'll take the gas turbine for simplicity, even though they sound funny and smell bad. ;D
Back in 1986, I sold my BMW R90S for a new fuel injected, electronic ignition BMW K75C. A riding buddy with a 1970 BMW 750 said he would never own one of those new BMW's because they were too complex to work on if something went wrong. Interestingly enough, whenever I’d call him to go riding, his bike ALWAYS needed to be worked on. Something always needed fixed. So while he wrenched... I rode. Any thoughts....
Oh, the turbine is much simpler, even if it took a while to get the materials right-though it took a lot less time compared to piston engines. Basically one moving part. Just one reason even short-hop commercial flights are mostly turbine powered. Jets even simpler.
Not sure I follow . They were a piston engine with valves and cams . Dusty
Piston engines with valves, cams, and a TURBOCHARGER (turbo = "TURBINE"). ;DOk, back to :pop
My 1960 BMW R-60 was supremely simple. Just about everything on it could be serviced or repaired by a fairly skilled hobbyist. However, it needed a great deal of maintenance...somet hing was required all the time. I enjoyed it and it never let me down, but eventually the desire to do more riding than wrenching overwhelmed my pride of self-sufficiency. My Vintage and my Bonneville are the compromises to simplicity that I chose...
You guys complaining about old beemers obviously never owned an old British bike ... or a Knuck/Pan HD ;D Dusty
