There was a thread on this topic a long while ago- no doubt
@youzguyz chimed in there too.
The 2.3s lean over a lot more than the2.5s. My theory is that Triumph wanted people to sit on the R/GT in the showroom, stand it up and think, "wow, this bike doesn't really feel all that heavy." That's why it has very little lean angle.
I'm with Mavorac and Youzguyz- it needs to lean over farther. You shouldn't have to go looking, more than you would with other bikes like the RIII, to find a place to park. In the US streets usually crown in the middle and slope down. If that slope is too steep (often) then parking on the right side of the street (US) means that with the kickstand down it has even less, or not enough, lean angle. Yeah, the solution is to back up nearly perpendicular to the curb with the rear tire pressing into the curb- that helps reduce the lean angle and the rear tire keeps the bike from going over. Not ideal.
Then, wind, I've driven to work on days when the wind comes in and spent the day worrying if the bike would get blown over. It takes less than you may think, especially since there isn't a whole lot of open space on that bike for the wind to pass through. It's one big, admittedly heavy.... sail.
I'm sure I'm not the only one who does not like this long kickstand. Any surface even slightly less than horizontal that slopes down to the right rules out a potential parking spot. What's more concerning to me is that even on a modest slope the other way a good gust of wind could potentially...
