While the full-size bike did nothing for speed, it did overcome one of the impediments to small bikes. Many people refuse to ride a small bike as it doesnt fit their image. Most people looking at the hyo 250 thought it was a "real" bike. Blowing up was a big problem. Finding engine parts is probably hard but there should be lots of everything else sitting in scrapyards with low miles.They were t*rds top to bottom.
A 250 based on a 650, way too heavy and slow as 50wt in January with a tendency to blow up without the slightest notice.
Not to mention that you'll never find parts for them in Canada any more.
