The mini-enduro (what Yamy called the original one --- 62cc I believe, but they called it 65) was really the first mini that was like a scaled down bigger dirt bike. Everything before that was more like the Honda 50 and 70cc mini-trails, with fold down bars, stamped wheels, etc.. My best friend back then's dad was a Yamaha regional manager. He got two free snowmobiles each winter to use for free, and two bikes each summer. He wouldn't use one of his two to get Andy a mini-enduro, but did bring one home for a weekend once. We'd been riding my Gemini SST 50cc 2-stroke, which was made in Taiwan from a Yamaha patent liscence. It was three gears up, had fold down bars, lights (though I'd taken them off) and stamped wheels, but would burn by Honda trail 70's even though it looked more like their 50. The original Yamaha mini enduro motor looked identical, but was noticeably quicker, at least to a twelve year old. It was also much nicer to have a real frame geometry underneath me, instead of a bulky little thing with some zip. It was more like the handling my Schwinn stingray gave me, which was the best I'd ever known. We pined over the thing after Woody took it back.
