So while we are going down this road.....
The main factor in determining the reliability is the level of stress all involved parts are under, assuming assembly was correct.
The R3 is rediculously overbuilt, and as a result, undersrressed in many areas. It's the 2JZ of motorcycles, so much headroom it's hard to believe. Look around you at similar displacement car motors and their power outputs, it hints at just how vastly undertuned the R3 is when stock.
Even with the 270 kit, it still only achieves power per liter equal to a Honda S2000. While that hp/liter is admittedly pretty high for a car, it's absolutely nothing for a motorcycle engine, many of which produce over 175hp/liter instead of the 120hp/liter the big carp kit makes.
Combined with the way overbuilt transmission, way overbuilt, shaft drive, and I can honestly say I see NO reason a 270kit rocket could last as long or longer than a bone stocker.
Apply the same line of though to the bonnie, and you'll find a platform in a similar situation, without the excessive overbuilt headroom the R3 has. Sure it can run high HP for some time, but I'd bet my bike the R3 motor tolerates 120hp/liter better and for longer than the 865 parallel twin will. There are a few factors the rockets wins, hands down. Much higher capacity cooling system, semi-dry sump oiling, 2vs3 cylinder issues (natural balance of the motor and even pulses applied to drivetrain) to name a few.
The bottom line though, a 270hp R3 vs a 95hp bonnie, both will be fun, both will be similar cost after buying a bonnie. The bonnie will deliver speeds and acceleration readily available at any kawahondasuzucatiamaha dealership on the current street fighter bikes. The rocket will be something no bike on a lot can duplicate in raw performance.
