Davez I own a 99 Yamaha Bigbear350 4x4 witch is basicily a moto4 350 just the name is different was changed to bigbear in 91 I believe...mine even sayes moto4 on the real mudflaps...but anyway alot has changed since the days they were called a moto4..but I know a guy that used to own a 87 yamaha moto4350 2wd and it was a great machine its the same size as the 4x4 model but is alot nimbler and better handling I think it would be a great choice for your wife...they ride good for a older model they have good power and good handling...my 99 is a 4x4 and its been great have not had one problem yet and I like it as much now as the day I brought it home from the dealer...but anyway teh the Bigbear or as yours is called moto4 would be great for you wife its a good solid reliable machine that is big and heavy enuf not to turn over on a litle stump..actualy my 99 model is very sturdy...but good luck and keep on 4wheeling...
