Seriously? Manufacturers do torture tests like this for “bragging rights,” testing and sales. In all the infinite wisdom of the google I can’t find the GPz900R test but I recall a great YouTube series on the ford eco boost engine they use in the f150 doing about four different types of torture tests to the same engine. I think they put 100,000 miles on it. Kia tests its engines for 300+hours at full load and above redline for short periods. I’m not talking about joe dirt chocking the front wheel and pinning the throttle on a production bike for a full day.
The point is, put oil in the damn bike, do some periodic maintenance and run it.
