You have already completed our usual first suggestion, training…to help you with some bike choice suggestions, what type of riding are you planning? Commuting, hiway, off road, just cruising?
Some bikes will combine a few of those…a dual sport would be my first suggestion for someone over 6ft, since they give decent leg room and offer the broadest range of riding capabilities (DR-Z 400S or the supermoto DR-Z 400sm)…but some don’t like the look of the bike…the next would probably be a standard style bike…(Ninja 250/500, Suzuki GS500, Honda Nighthawk 250)…then a cruiser, which also offer good leg room for pretty much everyone…you just have to go down to a dealer and sit on all the bikes to see what fits you and the type of riding you are planning…
Let us know what type of riding or what style of bike you prefer and we can try to help you out…but ultimately it will depend on how the bike fits you and how you feel riding the bike…
Later.
