not really.

The only thing thats gonne feel different is handling, but if you can sit on a bike in a riding postion for 30 min and still be comfortable then i'd say go for it. You definatly need to get your endorsment first though. As far as a test ride, you'd have to go with a euro or american brand, japanese vendors don't allow it. You could become friends with some people who ride and beg and plead to ride their's but i doubt it would do any good.
