Both good suggestions. If you can find one, a 28mm dildo may work too. I'd recommend one of the plastic ones though since the rubber ones may not be stable enough to hold the bike upright.
See any dry rot?
If the answer is no, install the tires and beat the hell out of them this summer.
If if the answer is yes, return them for tires with no dry rot.
I mean I know the only reason he gets on here is to hate on Casper. Honestly though that seems to be about the only thing mods actually do on these forums.
Yeah I think a 500 wouldn't last more than a year or 2.
For reference I'm 6'6 290 and I ride a triumph street triple r which is about the same ergonomics as a standard sv650 (non-s model). I think at 6'1 the OP would be comfortable on a standard sv650. However I do tend to agree that not every rider has to start on small displacement bike.
Supersports are very uncomfortable for me on longer days and I would not commute on one.
There is vented leather but leather will always be hotter than mesh. Armored mesh gear is good for Ohio summer. Leather starts to really suck when it gets up around 90. That said I wear my track leathers every time I go out for a ride in the country. Around town is jeans and a mesh jacket. Textile I can't comment on since I've never owned any.
Invest in some quality riding boots and gloves. I've seen some bad leg injuries that could have been prevented if the rider was wearing proper boots.
I have one very similar to this, it works ok. The material is very light though so I'm not sure how well it would survive a heavy windstorm or anything to that effect.
