This spotlight on the Version 1 YM240 is interesting. I haven't seen the facts about these drawn together into a single thread.
My YM240 Parts Manual says 'For YM240 1975 and later'. But the Nebraska testing was done in 1975 so I assume this model already had some market presence here by then - or they never would have heard of it. Does anyone know when this model started (in Japan as YM2000) or was first imported here?
I'll toss in a wild guess, unsubstantiated: it looks to me that YM1900 (years unknown) was the earliest version of this series.
284 noted the extreme ballast for the Nebraska test. I'll agree with his point about too much ballast to maintain speed going uphill. I first loaded my (oversize) rear tires to maximum with water and that required stopping to shift down a gear or two before attempting any upslope. After adding the ROPS (65 lbs behind the rear axle) I reduced the rear tire fill to 50%, which now seems about right.
